COMMON PUMP SPECIFICATIONS
FEATURES ●
Triplex plunger design provides a smooth liquid flow.
●
Specially formulated Hi-Pressure Seals together with concentric, polished Ceramic Plungers assure maximum seal life.
●
Compact, hollow shafted pump for direct mounting to either 1" gas or 3/4" electric shaft. Eliminates the need for pulleys, belts or gearboxes.
●
(11.4 L/M) (7 to 210 BAR) (8.0 mm) (3400 RPM)
Regulating Unloader with by-pass hose mounts directly onto pump for system pressure control and pump protection.
●
Stacked valve design for ease in servicing.
●
Fixed Chemical Injector for cleaning flexibility.

WARNING All systems require both a primary pressure regulating device (i.e., regulator, unloader) and a secondary pressure safety relief device (i.e., pop-off valve, safety valve). Failure to install such relief devices could result in personal injury or damage to the pump or to system components. CAT PUMPS does not assume any liability or responsibility for the operation of a customer’s high pressure system.

Optimum performance of chemical injector occurs with a 35 ft. high pressure hose and a minimum 3/8" I.D. The type of hose, extended lengths, reduced I.D. and fittings may create back pressures in excess of the low pressure nozzle rating and prevent the injector from drawing chemical. See Hose Friction Loss Chart in Service Manual. Deduct hose friction loss from above low PSI Nozzle. Consult CAT PUMPS for assistance with other options. CAUTION: Deduct the pressure drop shown in the performance chart from your desired system pressure to arrive at the maximum high pressure nozzle rating. This is essential to avoid over-pressurizing the pump.

INSTALLATION: A Regulating Unloader with Chemical Injector and By-Pass Hose comes with each 3SP pump to provide system pressure regulation, pump protection and metered chemical application. The Unloader is mounted directly onto the pump.
OPERATION: Set the unloader while the high pressure system is turned on. Adjust in small increments until the desired system pressure is reached. Install a pressure gauge to check pressure during start-up and periodically during operation. If unit is infrequently used or periodically stored, seals and O-Rings may become dry. Check seals and O-Rings before commencing operation. The system must be purged before operation (system liquid must flow through the pump without discharge restriction) to assure full system pressure is reached.
NOTE: For correct nozzle selection, read system pressure at the pump. DO NOT READ SYSTEM PRESSURE AT THE HIGH PRESSURE GUN. Incorrect pressure reading may result in: pump operation at excessive pressures, inconsistent chemical draw or possible damage to the pump or unloader.
SERVICE: The unloader should be serviced on the same schedule as your pump. Replacing the O-Rings is generally all that is required. Lubricate the ORings for ease in installation and replace all O-Rings included in the kit. Examine the seating surfaces of the seat, ball and valve assembly, and valve stem and replace as needed. Check the spring and replace as needed. Examine the check valve and replace as needed. Thread the adjusting cap onto the unloader and reset system pressure. Refer to 3SP Service Manual for start up, torque requirements, troubleshooting and servicing the seals and valves.
