Mud Pump Piston Seals

During oil drilling, mud pumps are the core of the drilling liquid circulation system and the drilling facilities, as they transport the drilling wash fluids downhole to wash the drills and discharge the drilling liquids.

The most important part of a mud pump with the function of ensuring mud circulation is the piston.

The sealing of the piston will fail very easily under complex and harsh working conditions, and consequently, the abrasive mud easily enters the kinematic pair of the cylinder liner, abrading the piston surfaces and reducing its service life and drilling efficiency.

The pump, through a series of pipes, inputs the high pressure fluid from the top of the drilling pipe through a device called “swivel” or “adduction head“; the fluid comes out from a series of nozzles at the bottom of the well, under the drill bit.
