Identification This overview contains general information about the machine, with the objective of providing information about the definition, purpose, overall operation and area of application of the machine. 1.1 General 1.1.1 Description of the machine Van der Ende Groep HD pumps are available in a number of versions. Van der Ende Groep selects the correct components using a computer program on the basis of key requirements such as pressure and capacity, the operating time and the medium to be pumped. A pump set is composed of a suitable plunger pump assembled with an electric motor (2-pole, 4-pole or 6-pole). The high pressure plunger pumps are supplied by various manufacturers, namely Danfoss, Pratissoli and Hawk. Each of these manufacturers has a wide range with various types of pumps. A HD pump set consists of the following components: 1. Drive: 2-pole, 4-pole or 6-pole electric motor; 2. Lantern piece: part between the flange of the motor and the flange of the pump; 3. Pump: axial displacement pump or triplex plunger pump; 4. Pump bracket: metal bracket which fits the base of the electric motor; 5. Vibration damper; 6. Pulsation damper: mounted on the discharge side of the pump (optional); 7. Gauge: mounted on the discharge side of the pump; 8. Overflow valve: mounted on the discharge side of the pump; 9. Hose tail: mounted on the suction side; 10. Flex coupling: between the output shaft of the motor and the output shaft of the pump. 1.1.2.

HD pumps may only be operated if they are installed in a suitable pipeline and water system. HD pumps may not be used for any purpose other than described above, or when failure of the HD pump could cause potentially dangerous situations. 1.3 Media Because gaskets and pump parts have limited chemical resistance, an HD pump may not and cannot simply be used with any medium. The standard pump installations are only suitable for water which is clean both chemically and mechanically. Special materials must be used for an HD pump which pumps osmosis water. For more information and advice, contact the sales department at Van der Ende Groep. If media are used which are not suitable for the selected pump, the guarantee will become invalid. 1.4 Control and operation A high-pressure pump is driven by an electric motor which can be started manually or controlled remotely. Additional controls and connections, such as a control cabinet or similar, are not covered by these instructions. The operating pressure must be set manually by adjusting the overflow valve. Turning the button on the top of the overflow valve clockwise will increase pressure, turning it anticlockwise will reduce pressure. 1.5 Users In principle, an HD pump is not controlled directly but by a user/operator with a control panel or other type of external control. Intended users must be at least 18 years old, employed at the company where the HD pump is installed, and designated by the management as competent and authorised to operate the HD pump. Unintended users are any users who do not meet the above definition. Unintended users are all users who, by using the HD pump, create unsafe situations or danger to themselves or others. 1.6 Operating environment An HD pump may only be put into operation if it is installed into a suitable system. When installing the pump, the following points must be respected:  The inlet pipeline must be one size larger than the inlet size on the suction side of pump;  Place the pump on a flat surface and below the water level, unless an inlet pressure pump is used;  Avoid constrictions, bends, T-connectors and other elements which hinder the flow in the inlet pipeline;  Both the inlet and discharge pipelines must always use flexible fittings to absorb any vibrations which arise (pulsations and pressure shocks);  Teflon tape or similar must not be used for sealing connections, pipes, fittings, etc., since this tape could end up in the pump. Instead, it is recommended that a liquid sealing material, such as Loctite 542, is used to create airtight seals;  Use appropriate filters with sufficient capacity in the inlet pipeline, and regularly check these for contamination to ensure sufficient flow is maintained;  Avoid creating a closed pressurised pipeline system, especially when working with a high- temperature medium, high working pressure and high capacity;  It is advisable to install a pressure gauge in the inlet pipeline to monitor the inlet pressure;  Install an overflow relief valve on the discharge side, and set it to a maximum of 10% above the maximum operating pressure.

Make sure that filters never become clogged, and regularly check for contamination. Clean if necessary, and install an inlet pressure safety switch after the filter. Figure 2 Installation example The HD standard pump is not intended for use in potentially explosive atmospheres. Check with the manufacturer about options on building the pump set using ATEX components. 1.7 Guarantee provisions The guarantee is valid for 6 months from the date shown when the machine was put into service, or two years from date of manufacture, whichever is earlier. The date shown when the machine was put into service is the time when the pump was installed in the system. If a claim is made under guarantee, the parts concerned must be presented to the manufacturer for assessment. The guarantee shall be invalid in the event of any of the following;  improper use or installation;  repeatedly ignoring advice of the manufacturer or supplier;  repair, maintenance or use by unauthorised persons;  use of inappropriate power supply or water connections;  use of the machine in an unsuitable environment;  intentional damage or modification of the machine.

Since this concerns an unfinished machine, it is not possible to meet all the provisions and essential safety on delivery of the machine. A list may be requested from the supplier. The CE mark is located on the sticker on the lantern piece. In accordance with the Low Voltage Directive, the HD pump is classified as a Class I device. 1.9 Residual risks It is neither practically nor economically feasible to eliminate 100% of all risks. In addition, risks associated with the machine are closely linked to what the machine does. These residual risks are listed below in a table. It is important that the user is aware of the fact that there are risks associated with the use of this machine. Observe safety precautions to the full to minimise any risk.

Beschrijving In het hoofdstuk beschrijving wordt uiteengezet wat de machine precies is, het is de achtergrondinformatie die nodig is om de machine correct en veilig te kunnen gebruiken. Een A, B, C, D, E, F, G of H tussen haakjes verwijst naar een onderdeel in afbeelding 6. 2.1 Werkingsprincipe Een HD pomp bestaat uit een aandrijfdeel en een pompdeel. Het aandrijfdeel, een elektromotor, is middels een flexkoppeling en een lantaarnstuk verbonden aan het pompdeel. Een HD pomp werkt volgens het verdringerprincipe. Een krukas in het pompdeel, aangedreven door de elektromotor, zorgt ervoor dat de plunjers in beweging komen. De meeste triplex plunjerpompen hebben drie zuiger/plunjers. Axiaal plunjerspompen bevatten naarmate de grootte toeneemt vijf tot elf zuigers/plunjers. Door het heen-en-weer bewegen wordt er beurtelings vloeistof aangezogen en vloeistof in de persleiding geduwd. Als de flow per plunjer in een grafiek wordt weergegeven is deze in de vorm van een sinus. Bij drie plunjers zijn per omwenteling drie lijnen in de vorm van een sinus te zien die elkaar overlappen. Hierdoor wordt de flow al wat constanter. Door een pulsatiedemper aan de perszijde te monteren worden de pieken in de flow en druk wat uitgevlakt waardoor deze nog wat constanter en rustiger is. 2.2 Algemeen Overal, waar hoge werkdruk en relatief weinig water wordt vereist, is de plunjerpomp het juiste gereedschap. Plunjerpompen vallen onder de hoofdgroep "verdringerpompen" en brengen afhankelijk van de plunjerdiameter en het aandrijftoerental een constante hoeveelheid water. De werkdruk wordt bepaald door de constructie van de diverse pompdelen en het aandrijfvermogen. De HD pompen van Van der Ende Pompen zijn beschikbaar in verschillende samenstellingen. Van der Ende bouwt, afhankelijk van de gewenste capaciteit en werkdruk, een geschikte plunjerpomp samen met een aandrijving tot een pompset. Afhankelijk van de selectie wordt een 2-, 4- of 6-polige elektromotor gebruikt als aandrijving. De hoge druk plunjerpompen komen van verschillende fabrikanten te weten: Danfoss, Pratissoli en Hawk. Deze hebben elk een groot assortiment met verschillende typen pompen. Het doel en de functie van een HD pomp is het op de juiste werkdruk houden van een watersysteem en een voldoende capaciteit leveren aan een watersysteem. Daarbij wordt de elektromotor veelal aangestuurd door een frequentieregelaar. Door de elektromotor de juiste kant op te laten draaien worden de plunjers in de pomp in beweging gebracht. Iedere omwenteling geven de plunjers een vast slagvolume, het vloeistofvolume dat wordt verpompt is recht evenredig met het toerental. Omdat drie plunjers geen constante flow genereren, wordt op de pers (F) een pulsatiedemper (D) gemonteerd om de pieken uit te vlakken. Dit geld alleen voor een Hawk en Pratissoli. Ook worden standaard een manometer (B) en een overstortventiel (A) gemonteerd. Daarnaast adviseren wij om een drukschakelaar/sensor (H) te plaatsen in de pers (C). Hiermee kan een te hoge of lage druk gemeten worden om de pomp en de installatie te beveiligen. Het overstortventiel leidt het teveel aan vloeistof weg via een overstortleiding. Met het overstortventiel kan een bepaalde druk op het syteem worden ingesteld. Wanneer er geen water wordt afgenomen wordt al het water via de overstort afgeleid. Een HD pomp is bedoeld om schoon water vanuit een reservoir onder hoge druk in een leidingsysteem te persen. Een HD pomp mag alleen draaien wanneer er voldoende voordruk en water toevoer is op de zuigaansluiting (E) van de pomp. Daarom wordt ook ten zeerste geadviseerd om een voordrukbeveiliging (G) te installeren.

Safety instructions You must read this installation manual carefully before installing an HD pump, and respect all the safety instructions. HD pumps may only be used for the purpose for which they were designed. An HD pump is designed to pressurise clean water from a reservoir into a pipeline system. HD pumps may only be operated if they are installed in a suitable pipeline system. During maintenance or repair, the power supply must always be disconnected, and the system relieved of any residual pressure. In order to disconnect the power supply, the isolation switch of the control element (control cabinet or similar) must be switched off and locked into position. After maintenance or repair, always fully reconnect and test everything. Only qualified personnel may carry out maintenance or repairs, and connect the electrical part of the pump. Always connect the earth wire to the terminal marked with the earth symbol. Make sure the power is connected to an earthed end circuit, fitted with a circuit breaker with appropriate rating. Always respect all installation and safety regulations. Ignoring these rules may result in severe injury to persons and/or damage to material. When turning off the pump, make sure there is no residual pressure in the HD pump, and that it is isolated from the rest of the system.

Installation Since an HD pump is an unfinished machine, it is not possible for the manufacturer to include all the essential safety devices, such as logic control and emergency stop. It is important, therefore, that the installer takes care of these aspects. In principle, all required safety devices are included in the installation instructions. After installation, the installer must make sure that the whole unit fully conforms with relevant European legislation. 4.1 General The pipeline system into which the HD is installed must comply with the following requirements:  Overpressure protection (I) must be installed; o The overpressure protection must activate if the pump or pipeline reaches maximum working pressure.  Flexible hoses must be used for connections; o This prevents vibrations from being transported and breaking pipes.  A motor protection switch must be installed and set to the correct flow;  An isolation switch must be installed within view of the pump. If this is not possible, it must be possible to lock the isolation switch into position with a padlock or similar;  All pipelines and fittings must be able to withstand the maximum pressure that the pump can provide;  All pipelines must be liquid-tight and in good condition;  The inner diameters of supply, drainage and overflow pipes must be at least as big as that of the connections. Account should be taken of the total pipeline resistance, so that minimum pressure, maximum overpressure and pressure losses of pipelines and the like are not exceeded. 4.2 Assembly  Place the HD pump set in an appropriate place: o make sure the surface is stable; o make sure the pump is standing horizontally; o make sure that vibrations cannot move the pump from where it stands; o make sure there is enough free space around the pump; o make sure the pump is protected from the weather.  Connect the inlet/suction pipeline: o use flexible pipes in connections;  this prevents vibrations splitting or breaking pipelines. o use a large enough filter:  maximum degree of filtration 200 microns (for Danfoss, pre-filtration of 10 microns with a ß10 value > 5000);  this prevents small particles and foreign objects from ending up in the pump and inlet pipelines; o make sure the inlet/suction pipe cannot become empty, even partially, when the pump is not on;  this prevents air entering the inlet/suction pipe;  if the pump runs dry, in other words, contains no liquid, it risks suffering irreversible damage.  Connect the discharge pipeline: o use flexible high-pressure pipes at the connection;  this prevents vibrations breaking pipelines. o install a non-adjustable or lockable overpressure protection device.

(This is only permitted under special circumstances, and requires temperature monitoring.)  this can negatively affect the operation of the pump if the pump is run without water being consumed from the pressurised side: the water temperature can rapidly rise and exceed the permitted 40°C. This can lead to a considerable reduction in operating lifetime, or irreparable damage. o use flexible pipes at the connection;  this prevents vibrations breaking pipelines. o it is advisable to collect any water discharged by the overpressure protection;  this means the activation of the overflow valve can be monitored. 4.3 Electrical The electric connection of the drive of the HD pump must be carried out by an authorised person. Pay attention to the correct rotation direction of the rotor shaft. Follow these steps:  Connect the earth: o Follow the instructions in the Attachment;  Connect the power supply: o Follow the instructions in the Attachment;  Connect the electric inlet pressure switch (optional): o Follow the instructions in the Attachment;  Use a motor protection switch with current setting to prevent damage to the electric motor: o Unless this current setting is already integrated in a soft starter, inverter or similar; o Check whether the current setting is set correctly (see Attachment);  Use an isolation switch: o This allows the machine to be disconnected from the power supply for maintenance or repairs;  Where necessary, use short-circuit protection;  If necessary, install an emergency stop button. If the electric motor is supplied by a frequency inverter, respect the following points:  Minimum and maximum speed;  Maximum rated current.

IBAN NL71 RABO 0340341610 · KvK Den Haag 27230471 · Btw-nummer NL8000.78.378.B01 · [email protected] · www.vanderendegroep.nl Pagina 14 van 21 Commissioning 5.1 Start up Before the HD pump is put into service, the following must be checked. If all these points are found to be OK, the HD set can be started. Check:  The oil level in the pump. The oil level must be at least as high as the middle of the sight glass. If necessary, add oil of the prescribed type;  The water tank (if applicable) and any suction filters for internal contamination. If necessary, these must be cleaned;  If the water inlet is open, and/or there is sufficient inlet pressure;  If any water reservoir present is in accordance with regulations;  If the valve or valves to the suction filter or filters are open;  If the inlet/suction pipe and connections have no leaks;  If the connecting hoses from the discharge port are attached;  The minimum and maximum permitted drive speed. This must not be exceeded;  If the overflow valve is adjusted to the lowest or low pressure. Never let the pump run dry of either water or oil. Air in the pump or pipelines can result in irreparable damage to the pump. After the above points have been checked, the HD pump can be put into operation. The following steps should be followed in this respect.  Check the rotation of the drive;  Depending on use, it is recommended that the pump is allowed to run for a few minutes after starting before being put under pressure, so the oil can heat up;  Vent the pipeline system;  Pressurise the system by adjusting the overflow valve (A). Never set the pressure to more than the maximum value. This is specified on the pump sticker on the lantern piece;  Check if the pressure is correct;  Check all the connections, hoses and other fittings for any leaks;  If the high-pressure pump is being used for the first time, it is recommended that pressure is limited to 30 to 50% of the maximum working pressure for the first few hours. After several hours, the pressure can be gradually increased to the maximum pump pressure. In the first few hours, the oil temperature will rise sharply, after which normal operating temperature will be reached. During this period, regularly monitor the temperature and the level of oil in the crankcase;  If no problems arise during this period, the pump can be used for its intended purpose. Important: Accident prevention The installation must be carried out in such a way to reduce the risk of accidents to a minimum under normal operation. It should be stressed that the "razor-sharp" water jet from the spray gun is dangerous, especially at close range. Never spray in the direction of people, animals or electrical components such as switches, motors, switch cabinets, etc. 5.2 Taking out of service If the pump is taken out of service for an extended period of time, it is recommended that water is kept in the pump to prevent rust forming on the inside of the pump and the valves sticking. However, if there is a risk of frost, the pump must be drained or it could be broken by ice formation. Alternatively, anti-freeze can be used in the pump.

Maintenance Routine maintenance and inspection is always necessary. Danfoss pumps require maintenance every 8,000 hours. Clean filters and check for oil or water leaks daily. For Hawk and Pratissoli pumps, the following applies. Every 500 hours Every 1,000 hours Check the oil level Replace the oil Oil must only be replaced after the first 50 hours. Check or replace:  Valves  Valve seats  Valve springs  Valve guides Check or replace:  High Pressure gaskets  Low Pressure gaskets The set can be cleaned with a dry cloth; never use water on electrical parts. Do not use abrasive cleaners. Before working on the high-pressure system, make sure it has been depressurised and that the isolating switch is turned off. 6.1 General Frequency: weekly.  Turn the isolation switch off;  Depressurise the pump;  Check the oil level with the dipstick and/or use the oil sight glass: o the oil level should be at the mark; o for more on filling/changing oil, see 6.2;  Check that all connections are secure;  Check that all hoses are secure;  Check hoses for wear and damage: o replace if necessary;  Check connecting cables for wear and damage;  Check if all other nuts and bolts are tight;  Check the filter in the suction pipeline: o remove any foreign objects; o remove any dirt and scale deposits;  Check that the inlet pressure switch is working.

If oil is changed according to the chart below, the life of the pump can be extended considerably. Check Every 500 operating hours Change Every 1,000 operating hours or 12 months Table 6 Oil change schedule For practical reasons, it is better to change the oil when the pump is hot. The oil is then less viscous and flows more easily out of the sump.  Turn the isolation switch off;  Depressurise the pump;  Place a pan to collect oil under the drain plug;  Remove the drain plug;  Recover the old oil and dispose of it as hazardous waste: o if there is any water in the oil, directly contact the supplier; o if the pump leaks oil, directly contact the supplier;  Remove any metal particles that have collected on the magnetic drain plug;  Replace and tighten the drain plug;  Remove the oil filler plug;  Fill the pump with oil: o Only use “Shell Omala S2 GX 220” oil or which is attributed in the product specifications of the high pressure pump. Check the oil level carefully when filling; too much oil is just as harmful as too little. For pumps fitted with grease nipples on the piston seals:  Lubricate every 50 to 100 hours with HPF12 grease;  Use about 2 cm3 of grease per nipple each time.

Once the pressure exceeds the switching pressure of the pressure switch, the brown and blue cores are connected by the pressure switch. Several different pressure switches are available. Figure 7 shows an example of a pressure switch for the low-pressure side. Figure 5 Pressure switch circuit diagram, no pressure situation Figure 6 Pressure switch, high pressure Figure 7 Pressure switch, low pressure It is recommended installing this in a failsafe way so that there is a constant connection when there are no problems. If a wire breaks, an alarm is given. red blue brown Star connection Delta connection
