KTZ400 Plunger Pump – High-Pressure Triplex Pump for Oilfield Cementing & Fracturing

Product Overview

The KTZ400 Plunger Pump is a reciprocating, positive displacement, single-acting, horizontal three-cylinder plunger pump. With a maximum input power of 600 HP (447 kW), it is engineered for demanding intermittent well service operations. This pump is a cornerstone of our well service pump solutions, delivering the pressure and flow required for critical downhole applications.

Whether you are cementing a new well, fracturing a formation, or acidizing to improve production, the KTZ400 offers the durability and performance you need. It is a trusted component in cementing units like the GJC(Q)77-15 and GJC(Q)70-30, and its design emphasizes reliability and low maintenance costs.

Key Applications

The KTZ400 is widely used in the oil and gas industry for a variety of intermittent well operations:

Cementing: Pumping cement slurry to secure the casing in the wellbore.

Fracturing (Fracking): Injecting high-pressure fluid to create fractures in rock formations.

Acidizing: Pumping acid to dissolve formation damage and improve permeability.

Water Injection: For enhanced oil recovery and pressure maintenance.

Key Features & Benefits

Durable Power End: The power end uses a worm and worm gear reduction system, providing a high reduction ratio for smooth, stable operation and a long service life. The pump casing itself serves as the lubricating oil tank, and the lubrication pump is integrated, eliminating the need for an external lubrication drive.

Cost-Effective Maintenance: The fluid end features a split head design. Each plunger corresponds to a separate, individually replaceable pump head section. This significantly lowers maintenance costs and reduces downtime.

Versatile Performance: The pump is equipped with different plunger diameters ranging from 3.375" to 4.5". This allows you to customize the pressure and flow to meet the specific requirements of your operation.

Easy Installation: The input shaft of the power end is aligned in the same direction as the plunger, simplifying installation and power drive.
