Series 550
Extraordinary
The P550 series three-cylinder piston pump is theoretically capable of handling input power up to 550 horsepower (400 kW). It ranges from a minimum pressure output of 10,877 pounds per square inch (psi) at 72.03 gallons per minute (750 bar equates to 272.7 liters per minute) to a maximum pressure of 40,000 psi at 18.8 gallons per minute (2750 bar equates to 71.2 liters per minute).

The flow values provided here refer to “theoretical” flow and do not account for efficiency reduction due to water compressibility and expansion of pressurized components.
Within this performance range, you can match your engine power according to your specific needs. Please note that piston diameter, stroke, and other factors have not been considered here, so the flow rate may be higher than the actual flow rate.
