Documentation & Service
🔧 Cat Pumps CP Stainless Steel Plunger Service Manual (PDF)
The data sheet carries the specifications, the exploded view, the numbered parts list and the seal and valve kit tables. The service manual covers installation and start-up, valve and seal servicing, the torque chart and troubleshooting.
Cat Pumps does not publish a separate data sheet for this valve configuration, so no specification table is shown here rather than borrow one from a neighbouring model. Tell us your duty and we will confirm the specification with Cat Pumps before you order.
Performance & Sizing
The 5CP6281CSS.0220 is a positive-displacement triplex plunger pump, so it has no flow-versus-pressure curve in the sense a centrifugal pump does, and Cat Pumps does not publish one. Flow is set by the plunger displacement and the shaft speed and stays essentially constant as discharge pressure rises. Pressure is set by the restriction downstream — the nozzle, orifice or membrane array — and capped by the regulating device, not by the pump.
The 5CP is a belt-drive frame, so the drive ratio sets the pump speed. To run at a speed other than the rated speed, or to size a motor and pulleys, use the relations printed on the Cat Pumps data sheet:
| Flow at another speed | Desired GPM = Rated GPM × (Desired RPM ÷ Rated RPM) |
| Required horsepower | HP (electric brake) = GPM × PSI ÷ 1460 |
| Motor pulley size | Motor pulley OD = (Pump pulley OD × Pump RPM) ÷ Motor RPM |
Maximum ratings apply individually — do not assume maximum flow and maximum pressure can be taken together. A primary pressure-regulating device and a secondary safety relief device are both required in the system. Talk to us before ordering if your duty sits near a limit.
