Overview Product Description

The mud pump piston assembly is one of the main parts of the hydraulic end system of the mud pump.The discharge pressure of the mud pump is generated by reciprocating linear motion of the piston assembly in the piston.Piston assembly by the piston core, rubber, spring, pressure plate, etc.

Our mud pump pistons are strictly manufactured according to API Standard, which with a high performance in various well drilling environment. The hub is forged from high quality steel, and the piston rubber is made from specially formulated compounds which are of heat, oil and water resistance. It is interchangeable with all other API standard designed pistons. And the valve rubber is easy to install.Mud Pump Piston Model_{BOMCOF-500F-800F-1000F-1300F-1600F-1600HLF-1600LF-2200HLHong HuaHHF-500HHF-800HHF-1300HHF-16003NB-1600F5NB-16005NB-2400 EMSCOF-500F-800F-1000F-1300F-1600FD-1000FC-2200FB-1300Gardner Denver}PAHP7P8/9P10/11PXLPX-11PZLPY-FXD_{National7-P-508-P-809-P-10010-P-13012-P-16014-P-20014-P-220N-1000/1300OilwellA-850-PTA-1100-PTA-1400-PTA-1700-PT    TSCWF-500WF-800WF-1000WF-1300WF-1600WF-2000WF-2200 IDECOT-500T-800T-1000T-1300T-1600}  

Mud Pump Valves and Seats:
We manufacture and offer 5 different styles of valves & seats as per API standard to fit your 

drilling needs, suiting to almost all popular mud pumps in the world. The stem guided valve and

seat and the wing guided valve and full open seat offers many advantages for today's higher

pressures and faster drilling operations: The Stem Guided valve and seat and the Wing Guided

valve and full open seat offers many advantages for today's higher pressures and faster drilling 

operations. 

Stem-guided valve & Tri-arm seat 
Features- greater fluid flow than four-arm seats, as well as it features an extra wide metal to

metal seal on the valve flange, . The serrated upper surface on the valve gives a longer non-

breathing seal between valve body and insert while the rigid seat cross-arms give greater

strength and positive sealing. The strong, thick, valve knock off nut holds the insert tightly 

reducing flex and breathing which lessens the chance of foreign matter getting between valve 

and insert.

Three-wing guided valve & Full open seat 
Three-wing guided valves and full open seats features greater fluid flow than four-wing valves, 

the unibody forged valve features greater strength than traditional welded-wing valve. 

Innovative unibody valve design eliminates snap rings, plates or keepers providing. 

Four-wing guided valve & Full open seat 
We offer two style of Four-wing guided valves and full open seats which feature greater fluid

flow through the full open seat. The full open seat provides easier valve maintenance and seat

pulling, in valve-over- valve fluid ends. 

Innovative unibody Four-wing guided valve & Full open 
Seat valve design eliminates snap rings, plates or keepers providing reduced maintenance by

snap-on valve inserts and easy installation. This combination will handle lost circulation material

better than most conventional style valves and seats while the seating angle greatly improves

flow characteristics and the heavy-duty load bearing capacity greatly improves service life. 

The unibody forged Four-wing guided valve & Full open 
Seat features greater strength than traditional welded-wing valve. Innovative unibody valve

design eliminates snap rings, plates or keepers providing reduced maintenance by snap-on

valve inserts and easy installation.
