Like the 4200 series, the P380 series three-cylinder piston pump can theoretically handle input power of up to 380 Hp(279 Kw).From a minimum pressure output of 10877 Psi at 45.8Gpm (173.4 L/Min at 750 Bar) to a maximum pressure of 40000 Psi at 12.68 Gpm (48 L/Min at 2750 Bar).

The internal deceleration method eliminates components such as belts and clutches, reducing space usage and allowing the high-pressure pump unit to have a relatively small overall size, which also indirectly lowers manufacturing costs. Continuous cooling water carries away most of the heat in the crankcase through built-in brass cooling fins, providing ample assurance for long-term stable opera-tion of the equipment.
Plunger Pump Parameters
Note:
1 Bar = 0.1 MPa
1 L/min = 0.06
1 kW = 1.36 hp
The flow value here refers to the "theoretical" flow and does not take into account the efficiency reduction caused by the compressibility of water and the expansion of pressure-bearing compo-nents. within this performance range, you can match your engine power according to your own needs. lt should be noted that factors such as plunger diameter and stroke are not considered here, so the flow will be larger than the actual flow.

The flow value here refers to the 'theoretical' flow, without considering the efficiency reduction caused by the compressibility of water and the expansion of pressure-bearing components.
Here we only illustrate the conventional plunger matching data for this high-pressure pump. Within this range, you can also customize the required plunger parameters to meet your actual usage needs.
