The P70 Series is a three-cylinder plunger pump specially customized for waterjet cutting applications. It features enhanced pressure-bearing capacity of all fluid end components.
The P70 Series is a three-cylinder plunger pump specially customized for waterjet cutting applications. It features enhanced pressure-bearing capacity of all fluid end components.
With a power input of 70 Hp (51 kW), it delivers a maximum pressure of 50,763 psi at 1.32 gpm (equivalent to 5 L/min at 3,500 bar).
When used with dedicated tools and mixed with abrasives, it can perform cutting operations on metal materials with a thickness ranging from 1 mm to 50mm

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 components. Within this performance range, you can match your engine power according to your own needs. It 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 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.
