Product Overview

Plunger Pump KTZ400 is introduced from the supplied model notes, parameters, and duty context.

The KTZ400 pump is a reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump with a maximum input power of 600 hp. It is widely used in intermittent oil well operations such as acidizing, cementing...

Maximum input power is 600 hp. The source configuration is reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump. It is positioned for intermittent oil well operations such as acidizing, cementing, and fracturing. The material highlights service access, installation flexibility, and corrosion handling.

Reading the model page together with Maximum input power is listed as 600 hp (447 kW) and Maximum strokes is listed as 244 rpm keeps the description grounded in the supplied data.

Model Focus

  • Series family: Plunger Pump Series
  • Maximum input power: 600 hp

Key Structural Features

Plunger Pump KTZ400 focuses on service access, installation flexibility, and corrosion handling in the structural description.

The technical description highlights service access, installation flexibility, and corrosion handling.

Plunger Pump KTZ400 keeps service access in view, which is useful when the unit is opened for routine checks. The installation-flexibility note matters because Plunger Pump KTZ400 can be arranged to suit the available equipment space. The corrosion-handling angle keeps Plunger Pump KTZ400 relevant for service conditions with more demanding media.

The extracted feature list keeps Plunger Pump KTZ400 grounded in 1. Composed of three main parts: the power end, the fluid end, and the partition plate connections, 2. The power end uses a worm and worm gear reduction system, providing high reduction ratios, smooth, and 3. The input shaft of the power end and the plunger of the fluid end are aligned in the same direction.

Reading the structure alongside Maximum input power is listed as 600 hp (447 kW) and Maximum strokes is listed as 244 rpm keeps the page closer to the source file.

  • 1. Composed of three main parts: the power end, the fluid end, and the partition plate connections.
  • 2. The power end uses a worm and worm gear reduction system, providing high reduction ratios, smooth operation, and long service life.
  • 3. The input shaft of the power end and the plunger of the fluid end are aligned in the same direction, facilitating the installation and power drive of the pump unit. The lubrication oil pump for the power end is integrated into the opposite end of the worm gear input shaft, eliminating the need for an external lubrication drive.
  • 4. The pump casing also serves as the lubrication oil tank for the power end.
  • 5. The fluid end pump head features a split design, with each plunger corresponding to a separate pump head section. Each section can be individually replaced, resulting in lower maintenance costs.
  • 6. Equipped with different plunger diameters (3.375" to 4.5") to accommodate various pressures and displacements, offering customers a range of options.

What the layout emphasizes

  • Theme focus: service access
  • Theme focus: installation flexibility
  • Theme focus: corrosion handling
  • Theme focus: stable long-run operation
  • Feature note: 1. Composed of three main parts: the power end, the fluid end, and the partition plate connections.

Application Areas

The service notes for Plunger Pump KTZ400 stay centered on intermittent oil well operations such as acidizing, cementing, and fracturing.

The source document lists intermittent oil well operations such as acidizing, cementing, fracturing, and water injection as the core service areas for Plunger Pump KTZ400.

The narrow application list prevents Plunger Pump KTZ400 from drifting into unrelated service claims.

When the operating table is read alongside 32 rpm, 70 rpm, and 128 rpm, the buyer can connect the duty point to the service condition more quickly.

The application discussion is easier to place beside Maximum input power = 600 hp (447 kW) and Maximum strokes = 244 rpm.

Selection / Configuration Notes

Check pressure/displacement balance, plunger size, and speed range before locking Plunger Pump KTZ400.

The 600 hp power rating for Plunger Pump KTZ400 only makes sense after pressure/displacement balance, plunger size, and speed range has been confirmed.

Plunger Pump KTZ400 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 KTZ400 is listed for intermittent oil well operations such as acidizing, cementing, and fracturing, 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 600 hp (447 kW), Maximum strokes is listed as 244 rpm, and Maximum connecting rod load is listed as 792KN.

Before ordering

  • Confirm the duty point against the table and the pressure window for Plunger Pump KTZ400.
  • Keep the pressure class, plunger size, and speed range aligned.
  • Keep the duty cycle and medium consistent with the package.
  • Power: 600 hp
  • Configuration: reciprocating, positive-displacement, single-acting, horizontal three-cylinder plunger pump
  • Primary use: intermittent oil well operations such as acidizing

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.

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.
