Product Overview

Plunger Pump KTZ900 is introduced from the supplied model notes, parameters, and duty context.

The KTZ900 pump is a reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump with a maximum input power of 900 hp. It is widely used in oil well operations such as acidizing, fracturing, and mud...

Maximum input power is 900 hp. The source configuration is reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump. It is positioned for oil well operations such as acidizing, fracturing, and mud injection. The material highlights service access, compact footprint, and installation flexibility.

The specification rows also give a second check through Maximum input power is listed as 900 hp (670 kW) and Maximum strokes is listed as 300 rpm.

Model Focus

  • Series family: Plunger Pump Series
  • Maximum input power: 900 hp

Key Structural Features

The feature text for Plunger Pump KTZ900 highlights service access, compact footprint, and installation flexibility.

The feature notes emphasize service access, compact footprint, and installation flexibility.

Plunger Pump KTZ900 keeps service access in view, which is useful when the unit is opened for routine checks. The compact footprint of Plunger Pump KTZ900 is helpful when the package has to sit close to other equipment. Plunger Pump KTZ900 is described with installation flexibility in mind, which makes layout planning easier for the buyer.

The extracted feature list keeps Plunger Pump KTZ900 grounded in 1. Composed of two parts: the power end assembly and the fluid end assembly, 2. Features a double-key eccentric wheel structure for the crankshaft, with involute helical gears mounted at, and 3. The pump is lightweight, compact, and capable of high pressure, making it suitable for small fracturing.

Those structural notes are easier to read when they are checked against Maximum input power is listed as 900 hp (670 kW) and Maximum strokes is listed as 300 rpm.

  • 1. Composed of two parts: the power end assembly and the fluid end assembly.
  • 2. Features a double-key eccentric wheel structure for the crankshaft, with involute helical gears mounted at both ends of the crankshaft to transmit power and counteract axial forces. The large and small gears are placed inside the pump casing, making full use of the effective space, reducing the overall pump width, and facilitating the pump layout.
  • 3. The pump is lightweight, compact, and capable of high pressure, making it suitable for small fracturing units (skid-mounted).
  • 4. The fluid end and the power end are connected by 8 alloy steel tie rods. When removing the fluid end, the tie rods remain attached to the power end. The connection between the plunger and the crosshead uses threaded connections, making disassembly and maintenance of the fluid end easy.
  • 5. The fluid end assembly can accommodate four different sizes of plungers (3.75", 4", 4.5" and 5"), providing various pressures and displacements for customer selection.

  • Feature note: 1. Composed of two parts: the power end assembly and the fluid end assembly.

Application Areas

The service notes for Plunger Pump KTZ900 stay centered on oil well operations such as acidizing, fracturing, and mud injection.

The source document lists oil well operations such as acidizing, fracturing, and mud injection as the core service areas for Plunger Pump KTZ900.

The narrow application list prevents Plunger Pump KTZ900 from drifting into unrelated service claims.

When the operating table is read alongside 100 rpm, 150 rpm, and 200 rpm, the buyer can connect the duty point to the service condition more quickly.

Those details, including Maximum input power = 900 hp (670 kW) and Maximum strokes = 300 rpm, help the buyer judge whether the duty point fits the model.

Selection / Configuration Notes

Plunger Pump KTZ900 should be matched to pressure/displacement balance, plunger size, and speed range.

Plunger Pump KTZ900 carries a 900 hp rating, so the drive package should be checked against pressure/displacement balance, plunger size, and speed range before release.

Plunger Pump KTZ900 is described as reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump, so layout fit and service access need to be reviewed together.

Plunger Pump KTZ900 is listed for oil well operations such as acidizing, fracturing, and mud injection, so the final package should stay matched to that duty set.

The model becomes easier to place when the selection notes are read against Maximum input power is listed as 900 hp (670 kW), Maximum strokes is listed as 300 rpm, and Maximum connecting rod load is listed as 532KN.

Before ordering

  • Confirm the duty point against the table and the pressure window for Plunger Pump KTZ900.
  • Review the plunger size, pressure class, and speed window together.
  • Match the selected package to the working medium and duty cycle.
  • Power: 900 hp
  • Configuration: reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump
  • Primary use: oil well operations such as acidizing

Practical Model Check

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

Send the model name, duty point, and speed-range constraints so the fit check stays specific.

When the pressure window or speed range drifts, change the final model instead of forcing the family name.

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.
