Fmc Bean P501870 Hsn Piston Cup for L1122 Fmc Pumps

Product Description

 

Product Description

 Cylinder Piston Cup is a crucial component in reciprocating pump systems, particularly in the cylinder or piston chamber. It is a set of rings or seals that are installed around the piston or plunger to create a dynamic seal with the cylinder wall. The primary function of cylinder packing is to prevent leakage of the pumped fluid from the high-pressure side to the low-pressure side of the pump. There are many sizes like 2.25″, 2.75″, 3" are available, and we can make many more size as per requirement.
 

FMC BEAN 420/435 Mud Pump Rubber Piston Cups

For preventing metal-to-metal contact between piston and cylinder during sliding (particularly in case of lateral forces), it is simple assembly and wear-resistant. The Piston cup can be used in several media ranging from water, mud and dry-running applications, it has good media resistance. Piston cup offer very good gliding behavior, good emergency running properties. Additionally, they help to attenuate mechanical vibrations.

FMC 420/435 Zirconia Ceramic Cylinder Liner

Ceramic cylinders are high-performance components installed in the fluid end of mud pumps, serving as the lining or sleeve for the main pump cylinder. Their primary function is to withstand extreme wear and pressure caused by abrasive drilling fluids, while ensuring smooth piston movement and maintaining internal sealing. Ceramic-lined cylinders dramatically increase service life compared to standard steel liners and reduce the frequency of part replacement. Manufactured from high-strength ceramics and often bonded to a stainless steel shell, these cylinders offer exceptional resistance to erosion, chemical exposure, and thermal stress. They provide a low-friction surface that enhances piston performance, reduces heat buildup, and ensures consistent fluid delivery under high-pressure conditions.

Our ceramic cylinders are fully compatible with mud pumps from FMC BEAN, ATLAS COPCO (Trido series), and TRIAQUA, and are available in multiple sizes (e.g., 2.75", 2.25") to suit different flow and pressure requirements.
