A compact footprint gives Plunger Pump KQZ2500 more room to fit into tighter service layouts. The configuration range around Plunger Pump KQZ2500 helps the same model family address different operating targets.

The source wording for Plunger Pump KQZ2500 still centers on Composed of two main parts: the power end assembly and the fluid end assembly, Features an integral crankshaft structure supported by heavy-duty cylindrical roller bearings. The crankshaft, and The pump is lightweight, compact, and high-pressure, making it a standard product for large fracturing trucks.

Those structural notes are easier to read when they are checked against Maximum input power is listed as 2500 hp (1865 kW) and Maximum strokes is listed as 330 rpm.

  • Composed of two main parts: the power end assembly and the fluid end assembly.
  • Features an integral crankshaft structure supported by heavy-duty cylindrical roller bearings. The crankshaft ends are equipped with two pairs of involute helical gears to transmit power, reducing transmission noise and extending gear life.
  • The pump is lightweight, compact, and high-pressure, making it a standard product for large fracturing trucks and widely used in the market.
  • The fluid end and power end are connected by 20 alloy steel tie rods. When removing the fluid end, the tie rods remain on the power end. The plunger and small connecting rod are connected with clamps, making it easy to disassemble and maintain the fluid end.
  • 5. The fluid end assembly is equipped with four different sizes of plungers (3.75", 4", 4.5", 5") to offer various pressure and flow rate options for customer needs.

Application Areas

Plunger Pump KQZ2500 is positioned for fracturing operations in intermittent oil well service.

Plunger Pump KQZ2500 stays centered on fracturing operations in intermittent oil well service in the extracted application notes.

That scope matters because it keeps the page focused on the real duty point instead of turning Plunger Pump KQZ2500 into a generic pump description.

The speed and operating table can be compared against 111 rpm, 150 rpm, and 200 rpm to keep the duty point visible.

Those details, including Maximum input power = 2500 hp (1865 kW) and Maximum strokes = 330 rpm, help the buyer judge whether the duty point fits the model.

Selection / Configuration Notes

The final selection for Plunger Pump KQZ2500 depends on pressure/displacement balance, plunger size, and speed range.

For Plunger Pump KQZ2500, the 2,500 hp rating needs to sit alongside pressure/displacement balance, plunger size, and speed range before the order is fixed.

Plunger Pump KQZ2500 is described as reciprocating, positive-displacement, single-acting, horizontal five-cylinder plunger pump, so layout fit and service access need to be reviewed together.

For Plunger Pump KQZ2500, the recorded applications are fracturing operations in intermittent oil well service; keep the actual medium, pressure, and cycle aligned with the target job.

The specification block gives an additional checkpoint through Maximum input power is listed as 2500 hp (1865 kW), Maximum strokes is listed as 330 rpm, and Maximum connecting rod load is listed as 192325 lbf (854900N).

Before ordering

  • Confirm the duty point against the table and the pressure window for Plunger Pump KQZ2500.
  • Check plunger size, pressure class, and speed range before release.
  • Match the selected package to the working medium and duty cycle.
  • Power: 2,500 hp
  • Configuration: reciprocating, positive-displacement, single-acting, horizontal five-cylinder plunger pump
  • Primary use: fracturing operations in intermittent oil well service

Practical Model Check

Plunger Pump Series should be read together with the table and the duty point.

If you need the best-fit model, send the model name, required duty point, and any plunger-size or speed constraints.

The family may stay close, but the final model should change if the plunger fit is off.

Quick check

  • Series family: Plunger Pump Series
  • Selection focus: pressure/displacement balance, plunger size, and speed range
  • Use the parameter table before quotation and keep the pressure window visible.
  • Confirm the working medium, duty cycle, and pressure path.
