The 4200 series three-plunger pump can theoretically handle an input power of up to 360 horsepower (264 kW).From a minimum pressure output of 45.96 Gpm 10877 Psi (174 liters/min at 750 Bar) to a maxi-mum pressure output of 12.1 Gpm at 40000 Psi (45.9 liters/min at 2750 Bar).
The 4200 series three-plunger pump can theoretically handle an input power of up to 360 horsepower (264 kW).From a minimum pressure output of 45.96 Gpm 10877 Psi (174 liters/min at 750 Bar) to a maxi-mum pressure output of 12.1 Gpm at 40000 Psi (45.9 liters/min at 2750 Bar).
Unlike other series of plunger pumps, the 4200 series three-plunger pump uses belt reductior,and diesel engine equipment is usually used with a clutch,enabling the pump unit to have better heat dissi-pation performance and a longer service life.
With a relatively high performance output, it is destined that it cannot be operated solo without toolassistance, as the significant recoil and destructive power pose a great safety risk to personnel. ts useis usually combined with different industry-specific application mechanisms, or the output perfor-mance is distributed across 2-3 dedicated tools (such as overflow guns, gun heads, foot-operatedvalves, etc.).
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" flowand does not take into account the efficiencyreduction caused by the compressibility of waterand the expansion of pressure-bearing compo/nents. Within this performance range，you canmatch your engine power according to your ownneeds. lt should be noted that factors such asplunger diameter and stroke are not consideredhere, 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 ilustrate the conventional plunger matching data for this high-pressure pump. Within thisrange, you can also customize the required plunger parameters to meet your actual usage needs.
