QWS2800 Fluid Ends
QWS2800 Fluid Ends are high-pressure fluid-end assemblies designed for compatible QWS2800-class quintuplex fracturing pumps. Available in alloy steel and stainless steel configurations, they support demanding oilfield operations such as hydraulic fracturing, acidizing, and well servicing. Plunger sizes, material grade, pressure rating, and dimensional compatibility must be confirmed against the required pump configuration.

Description
QWS2800 Fluid Ends for Fracturing Pumps
Product Overview
The QWS2800 Fluid End is the high-pressure fluid-handling assembly of a quintuplex reciprocating plunger pump. It contains the working chambers and associated valve and sealing interfaces that control fluid intake and discharge during each pumping cycle.
Designed for compatible 2,800 HP-class fracturing pump systems, the fluid end is used in demanding oilfield applications requiring high-pressure fluid delivery. Available configurations may include forged alloy steel or stainless steel, depending on the operating conditions and approved design.
Key Features
Quintuplex pump configuration: Designed for compatible five-plunger pump systems.
High-pressure operation: Pressure capability depends on plunger diameter, pump speed, material, and the rated assembly configuration.
Material options: Alloy steel and stainless steel variants may be available.
Multiple plunger sizes: Published configurations include 3.75-inch, 4-inch, and 4.5-inch options; other configurations require confirmation.
Precision-machined interfaces: Valve bores, sealing surfaces, and mounting dimensions must match the approved drawing.
Replacement supply: Available for evaluation against the original pump model, part number, and technical documentation.
Typical Applications
QWS2800 Fluid Ends are used in oilfield pressure-pumping operations, including hydraulic fracturing, acidizing, well killing, and related well-service work. The correct assembly must be selected according to required pressure, flow rate, fluid characteristics, and pump configuration.
Replacement and Ordering Information
Please provide the pump manufacturer and model, original fluid-end part number, required material, plunger size, working pressure, and available drawings or photographs.
Before installation, verify dimensional interchangeability, material traceability, pressure rating, and the approved inspection and testing requirements. A QWS2800 designation alone does not establish that every supplier's fluid end is interchangeable.
