Performance & Sizing
The 1CX013RD4 is a positive-displacement triplex compact 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 1CX is a direct-drive frame, so the motor sets the pump speed directly. To work out flow at another speed, or to size the drive, use the relations Cat Pumps prints on its data sheets:
| Flow at another speed | Desired GPM = Rated GPM × (Desired RPM ÷ Rated RPM) |
| Required horsepower | HP (electric brake) = GPM × PSI ÷ 1460 |
Rated speed for this model is 1750 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.
