Xylem Flojet CW474 Series Manuals

On receiving your Flojet diaphragm pump check that the pump and model number and motor volts/phase/Hz correspond to your purchase order. Notify your supplier immediately in the event of any error, or of damage to the pump on receipt. Delay may cause difficulty with warranty claims. Installation. Locate the pump in a dry place above or below the liquid supply. The pump will self-prime when wetted to a height not exceeding 2 metres. The pump may be mounted in any attitude. If mounted vertically, the motor should be uppermost. The drain holes in the pump body should face downwards: if necessary, undo the 4 body screws and rotate the pump head through 90º or 180º. Attach the pump to a firm surface with fixing screws through the mounting feet. Connections. Port adapters available are 13mm (½”) hose barb and ½” NPT threaded. Use hose clips for hose connections and PTFE tape for threaded connections. Flexible hose is recommended. Inlet hose should be at least 13mm (½”) bore, of the reinforced type that will not deform or collapse under suction conditions. A ‘Pumpguard’ strainer is recommended to prevent solid debris from entering the pump. The strainer should be checked at intervals and cleaned when necessary. See Cleghorn Waring’s data sheet for details of ‘Pumpguard’ strainers and port fittings. Make sure that the inlet and discharge pipes and connections are airtight, to ensure prompt self-priming and no leaks. Electrical connection. The unit is complete with a standard European single phase 3 wire lead. Check the motor plate for the correct electrical supply and full load current. Make sure that the motor (and adjustable pressure switch, if fitted) are earthed. A starter with thermal overload protection should be used to protect the motor. A COMPETENT ELECTRICIAN SHOULD DO THE WIRING. Controlling the discharge pressure. The maximum recommended discharge pressure is 3.0 bar (45 p.s.i.). The pump is a positive displacement type that can be damaged by excessive back pressure.
