Fluid End Spare Parts produced by our company is mainly used in oil drilling and geological exploration, especially in deep oil reservoirs, poor surface structure and soil production environment, as well as offshore oil and gas development。

Valve assembly is the critical component of mud pump fluid end , with high operation frequency and great impact subjected. The quality of valve assembly will have a direct effect on the life of hydraulic cylinder.

Piston assembly is the major part of the mud pump fluid end. The discharge pressure of mud pump is generated by the up-and-down motion of the piston in the cylinder. Small piston—high pressure and low flow rate; Big piston—low pressure and high flow rate. Metric pump and inch pump adopts metric piston and inch piston respectively.

The structural features and properties of F series mud pumps are more advanced. Wearing parts of fluid end can be universally used with those of API standards.

F series mud pumps are firm and compact in structure and small in size, with good functional performances, which can adapt to drilling technological requirements such as oilfield high pump pressure and large displacement etc. The F series mud pumps can be maintained at lower stroke rate for their long stroke, which effectively improves the feeding water performance of mud pumps and prolongs the service life of the fluid end. The suction stabilizer, with advanced structure and reliable service, can achieve the best buffering effect. Power ends of the F series mud pumps adopt the reliable combination of forced lubrication and splash lubrication to increase the service life of power ends.

This series of pumps is manufactured strictly in accordance with API Spec 7K Drilling and Workover Equipment Specifications and carried out delivery test in accordance with the standard.

A mud pump (sometimes referred to as a mud drilling pump or drilling mud pump), is a reciprocating piston/plunger pump designed to circulate drilling fluid under high pressure (up to 7,500 psi or 52,000 kPa) down the drill string and back up the annulus. A mud pump is an important part of the equipment used for oil well drilling and manufactured according to API specification 7K.

The advantages of the drilling mud pump include the ability to move high-solids-content fluids laden with abrasives, the ability to pump large particles, ease of operation and maintenance, reliability, and the ability to operate over a wide range of pressures and flow rates by changing the diameter of pump liners and pistons.

The fluid end includes cylinders (module), valve assembly, cylinder liners, piston assembly, suction manifold, discharge manifold, piston rod, pulsation dampener assembly, etc.

As an important equipment for oilfield drilling operation, a drilling mud pump delivers circulating high-pressure drilling fluid or drilling mud to the bottom of the oil well, flushes the bottom of the well, breaks the rock, cools, lubricates and clean the drill bit, and carries the cuttings back to the ground.

The drilling mud is also used to suspend and carry out drill cuttings from the drill bits as it is brought in and out of the hole. This ensures that the drill bit does not clog and overheat, and makes the entire drilling operation smooth and safe.

Rotational power is supplied to the mud pump through an external power source like a diesel engine or electric motor. The power end of the mud pump converts the rotational energy through a crankshaft to a reciprocating motion of pistons.

The pistons move back and forth in mud pump liners, exerting a force on the cylinder chamber. During the retraction of the piston, valves open to allow the fluid to be drawn into the cylinder. Once the piston has fully retracted, it is pushed back into the cylinder.

At this time the intake valves are closed and the exhaust valves open, allowing the piston to force the fluid out of the cylinder under pressure. Once the piston reaches its maximum depth into the cylinder, the exhaust valves close and the process repeats.

For Fluid End: piston rod clamp, piston rod, piston assembly, cylinder cover, liner, liner flange, wear plate, cylinder, valve assembly, valve cover, valve guide, flashboard assy., cylinder cover flange, cylinder head, gaskets, studs, nuts, seal rings, pulsation dampener, bladder, discharge manifold, suction manifold, etc.
