Fluid Cylinder

The fluid cylinder is one of the most critical components in a mud pump, forming the core of the fluid end where drilling mud is pressurized and discharged. It houses the piston, liners, valves, and seats, and is directly responsible for containing high-pressure fluid flow during each pump stroke. Its structural integrity is essential for safe, efficient, and consistent mud circulation in drilling operations.
Manufactured from high-strength ductile iron, cast steel, or alloy materials, fluid cylinders are engineered to withstand extreme pressure, abrasion, and thermal stress. Many models include replaceable ceramic liners to enhance wear resistance and simplify maintenance. The precision-machined design ensures compatibility with other sealing and moving components such as packing, pistons, and valve assemblies.
Our fluid cylinders are fully compatible with mud pumps from FMC BEAN, ATLAS COPCO (Trido series), and TRIAQUA, and are available in various sizes to suit different flow and pressure requirements. These OEM-standard parts are ideal for pump overhauls, repairs, or upgrades.
