CAUTION: Do not over-lubricate air supply — excess lubrication will reduce performance. CAUTION: Do not exceed 8.6 bar (125 psig) air supply pressure. CAUTION: When choosing dampener materials, be sure to check the temperature limits for all wetted components. Example: Viton® has a maximum limit of 177°C (350°F) but polypropylene has a maximum limit of only 79°C (175°F). CAUTION: Maximum temperature limits are based upon mechanical stress only. Certain chemicals will significantly reduce maximum safe operating temperatures. Consult Chemical Resistance Guide (E4) for chemical compatibility and temperature limits.

NOTE: Not all materials are available for all models. Refer to Section 2 for material options for your pump. WARNING: Prevent static sparking. If static sparking occurs, fire or explosion could result. Dampener, pump, valves and containers must be grounded to a proper grounding point when handling flammable fluids and whenever discharge of static electricity is a hazard. CAUTION: The process fluid and cleaning fluids must be chemically compatible with all wetted dampener components. Consult Chemical Resistance Guide (E4). CAUTION: Dampener(s) should be thoroughly flushed before installing into process lines. FDA- and USDA- approved dampeners should be cleaned and/ or sanitized before being used. CAUTION: Always wear safety glasses when operating dampener. If diaphragm rupture occurs, process fluid may be forced out air exhaust. CAUTION: Before any maintenance or repair is attempted, the compressed air line to the dampener and pump should be disconnected and all air pressure allowed to bleed from the system. Disconnect all intake, discharge and air lines. Drain the dampener by allowing any fluid to flow into a suitable container. CAUTION: Blow out air line for 10 to 20 seconds before attaching to dampener to make sure all pipeline debris is clear. Use an in-line air filter. A 5μ (micron) air filter is recommended. CAUTION: Dampeners cannot be used in submersible applications. CAUTION: Tighten all hardware prior to installation. CAUTION: ATEX products have been assessed for use in potentially explosive atmospheres in accordance with the European Directive 94/9/ EC (ATEX 95). Users of ATEX products must be familiar with ATEX requirements and follow all safety guidelines. (Refer to Wilden Safety Supplement WIL-18510-E).

fluctuation. The Equalizer® minimizes unwanted pressure fluctuation by providing a supplementary pumping action. This is accomplished by using a diaphragm as a separation membrane within the Equalizer® to trap a given volume of liquid on one side and pressurized air on the other. When the fluid pressure falls in the system, the Equalizer® supplies additional pressure to the discharge line between pump strokes by displacing fluid via diaphragm movement. This movement provides the supplementary pumping action needed to reduce pressure variation and pulsation. The Equalizer® automatically sets and maintains the correct air pressure matching the variations in liquid flow or discharge pressure generated by the pump. A shaft attached to the Equalizer® diaphragm triggers the addition or removal of the air within the non-wetted side of the Equalizer®. The Equalizer® automatically adjusts to any pressure and/or flow setting of the pump with no need for manual adjustment of the unit and/or system. The Equalizer® has proven to be the cost effective choice for protecting your liquid process system from unwanted pulsation or pressure fluctuation. Contact your local Wilden distributor for further information on the Equalizer® and other pumping solutions. A compressed air line attached to the air regulator body sets and maintains pressure on the air side of the diaphragm. As the reciprocating pump begins its stroke, liquid discharge pressure increases which flexes the Equalizer® diaphragm inward. This action accumulates fluid in the liquid chamber (see Phase 2) and the air regulator allows compressed air to enter the air side. When the pump redirects its motion upon stroke completion, the liquid discharge pressure decreases and compressed air in the air side forces the Equalizer® diaphragm to flex outward displacing the fluid into the discharge line (see Phase 3). This motion provides the supplementary pumping action needed to minimize pressure fluctuation.

By reviewing the variation in pressure, the level of dampening can be estimated for an application. For example, the head pressure generated by a 25 mm (1”) pump operating at 6.89 bar (100 psig) air inlet pressure and 6.2 bar (90 psig) head pressure varies between 1.7 bar (25 psig) and 7.2 bar (104 psig) resulting in a total pressure fluctuation of 5.5 bar (79 psig) for each stroke. When an XSD1/AAAA/ TNU/TF dampener is installed in the application, the head pressure varies between 4.8 bar (69 psig) and 6.6 bar (96 psig) resulting in a pressure fluctuation of only 1.9 bar (27 psig).

S e c t i o n 6 S U G G E S T E D I N S T A L L A T I O N The model XSD1 has a 25 mm (1") inlet/discharge. The model XSD2 has a 51 mm (2") inlet/discharge and the XSD3 has a 76 mm (3") inlet/discharge. The Equalizer® can be installed in either horizontal or vertical orientations. A variety of materials are available to satisfy temperature, chemical compatibility, abrasion and flex concerns. The Equalizer® installed on the discharge side of the pump minimizes pulsation and protects in-line equipment. It can also be connected on the suction side to prevent water hammer associated with a positive inlet condition. Install the Equalizer® as shown below. The use of flexible connections and a Filter, Regulator, Lubricator (FRL) will extend parts life. Shut-off valves on the suction side of pump and the discharge side of Equalizer® will enable maintenance personnel to safely service the equipment. To maximize effectiveness, install the Equalizer® as close as possible to the discharge of the pump. It is important to support the pipe immediately downstream from the Equalizer®. Use a tee connector on the pump air supply line and connect the line to the Equalizer® regulator body. This tee connector should be installed after the FRL. The Equalizer® consumes very little air, therefore, a 1/4” hose is more than adequate to supply enough air volume. When the air supply to the pump is shut down, the air to the Equalizer® will be shut off as well. NOTE: In the event of a power failure, the shut-off valve should be closed if the restarting of the pump is not desirable once power is regained. AIR-OPERATED PUMPS: To stop the pump from operating in an emergency situation, simply close the shut-off valve (user supplied) installed in the air supply line. A properly functioning valve will stop the air supply to the pump, therefore stopping output. This shut-off valve should be located far enough away from the pumping equipment such that it can be reached safely in an emergency situation.

10 WIL-19011-E-07 T R O U B L E S H O O T I N G 1) When there is a significant drop in the fluid discharge pressure, there will be a noticeable release of air through the small bleed hole in the air regulator body. This is how the Equalizer® automatically adjusts itself for optimal suppression. This is a good way of verifying proper operation of the unit. If there is a continuous discharge of air out of this hole during steady fluid discharge pressure, the Equalizer® is not functioning properly and should be inspected. The air regulator body houses three (3) Glyd rings. 2) Fluid leakage around the clamp band area is normally stopped by tightening the clamp band bolts. If leakage continues, unit should be disassembled and inspected. 3) Air leakage between the adapter plate and air chamber requires tightening of four air chamber bolts on the inside of the air chamber.

S e c t i o n 7 D A M P E N E R D I S A S S E M B L Y To ol s R e q uir e d : • Deep well sockets and ratchet (7/16”, 1/2” and 3/4”) • Hex (Allen®) wrenches (3/16” and 1/4”) • Large adjustable wrench or channel lock pliers To ol s R e c o m m e n d e d : • Large pipe wrench • Vise equipped w/soft jaws (such as aluminum, plastic, plywood or other suitable material) CAUTION:  Before any maintenance or repair is attempted, the compressed air line to the Equalizer® and the pump should be disconnected and all air pressure allowed to bleed from the system. Disconnect all intake, discharge, and air lines. Be aware of any hazardous effects of contact with your process fluid. PLEASE READ ALL DIRECTIONS BEFORE STARTING DISASSEMBLY. NOTE: The model photographed for these instructions is a XSD1. Other Equalizer® models should be similar in design but may contain slightly different components and fastener sizes. Step 1 Disassembly of the surge ends/ small clamp band is needed only in the event of leakage. Leakage is usually stopped by tightening the small band bolts using a 7/16” deep well socket. Step 2 If leakage persists, remove surge ends and replace O-rings. Step 3 Remove large clamp band using a 1/2” deep well socket.

12 WIL-19011-E-07 Step 4 Set liquid chamber aside. Step 5 Remove reducer bushing at top of regulator. Step 6 Loosen shaft assembly by using adjustable wrench on outer piston and 3/4” socket on shaft bolt inside air regulator body. Turn counter clockwise. One of two scenarios will occur: outer piston will loosen from shaft, or the shaft bolt will loosen from shaft. Step 7 In either case, this will allow the removal of the inner and outer pistons, diaphragm, shaft stop, shaft, shaft stop washer and bolt. Step 8 Inspect shaft for nicks or abrasion. Small nicks can usually be dressed out. If shaft is chemically attacked or nicks are hindering operation, shaft should be replaced. Step 9 Disassembly of the air chamber from the regulator adaptor plate is needed only in the event of air leakage. D A M P E N E R D I S A S S E M B L Y

Step 10 In the event of an air leak, remove the air chamber and replace the gasket. D A M P E N E R D I S A S S E M B L Y Step 11 Disassembly of the regulator body from the regulator adaptor plate is needed only in the event of air leakage. Step 12 In the event of an air leak, remove the regulator adaptor plate and replace the O-ring. Step 13 Using an O-ring pick, remove the Glyd rings from air regulator body. Step 14 The air regulator body has five (5) grooves cut into the inside diameter. There are three Glyd rings installed in the 1, 3 and 5 positions. It is important that these Glyd rings be installed in the correct grooves so that the Equalizer® functions properly. Please refer to the drawing for the correct location of the Glyd rings. 5 3 1

INSTALLATION The following tools can be used to aid in the installation of the new seals: Needle Nose Pliers Phillips Screwdriver Electrical Tape • Wrap electrical tape around each leg of the needle nose pliers (heat shrink tubing may also be used). This is done to prevent damaging the inside surface of the new seal. • With a new seal in hand, place the two legs of the needle nose pliers inside the seal ring. (See Figure A.) • Open the pliers as wide as the seal diameter will allow, then with two fingers pull down on the top portion of the seal to form kidney bean shape. (See Figure B.) • Lightly clamp the pliers together to hold the seal into the kidney shape. Be sure to pull the seal into as tight of a kidney shape as possible, this will allow the seal to travel down the bushing bore easier. • With the seal clamped in the pliers, insert the seal into the bushing bore and position the bottom of the seal into the correct groove. Once the bottom of the seal is seated in the groove, release the clamp pressure on the pliers. This will allow the seal to partially snap back to its original shape. • After the pliers are removed, you will notice a slight bump in the seal shape. Before the seal can be properly resized, the bump in the seal should be removed as much as possible. This can be done with either the Phillips screwdriver or your finger. With either the side of the screwdriver or your finger, apply light pressure to the peak of the bump. This pressure will cause the bump to be almost completely eliminated. • Lubricate the edge of the shaft with NLGI grade 2 white EP bearing grease. • Slowly insert the center shaft with a rotating motion. This will complete the resizing of the seal. • Perform these steps for the remaining seal.
