We are offering mud pump. 1. The fluid end assembly mainly consists of fluid end, valve assembly, liners and pistons. Fluid end is made of forged alloy steel and three fluid ends of each pump are interchangeable. The suction valve and discharge valve of f mud pump are interchangeable. Liners are hy- chrome liners, the sleeve is made of wear resisting cast iron. Piston and piston rod are of slide fit and sealed with rubber seal rings and are fastened with lock nuts to prevent the piston from loosing. 2.the valve seat bores have bottom shoulders. The piston and liners are spray lubricated and cooled which allow an extended service life. 3. F-1000 mud pumps are rated at longer stroke length and relatively low stroke per minute. It can increase the service life of expendable parts of fluid end assembly the power end assembly mainly consists of frame, crankshaft, pinion shaft, crosshead and extension rod.

We are offering mud pump liner. Hna offers four different type of liners for all popular mud pumps to suit any drilling condition, including premium chromium liners, ceramic liners, chromium-plated liners and hardened liners. Premium chromium liners hna premium liners combine the strength of a forged steel outer shell with the abrasion and corrosion resistance of a high chromium iron inner sleeve. These liners feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minimum uniform bore hardness of 62 rc. Each liner is machined to close tolerances to assure ease of installation and long liner life with the inside diameter of these premium liners honed to a mirror-like finish for smooth even wear during the life of the liner. Hna premium liners are made for superior performance under tough corrosive and abrasive conditions. Ceramic liners hna ceramic liners combine the strength of a forged steel outer shell with the abrasion and corrosion resistance of a ceramic inner sleeve. We provide zirconia(zro3) sleeves as well as alumina(al2o3.) sleeves.

We are offering fluid end module assy. heat-treated and internally hardened for high durability; available in various materials to meet a wide range of applications; standard one-and/or-two-piece configuration, with designs available for pressure of 5000psi(35.1mpa), 7500psi(52.7mpa), and 10000psi(70.3mpa); discharge connections available on each side; suction connections on each side or front center. material is 35crmoa or 40crmonn alloy forged steel. To get better fiber texture, we use electric stove for second forging, or deoridation treatment. It is forged from three directions and the forging ratio is not less than 4.0:1.0. It can not have crack, impurity, looseness, overburns, etc. And weld is not allowed. It should be confirming to the stipulation of jb/tq252-81, and should be checked by grade� after quenching the rough module will be rough processed, then the hull hardness is hb285-330. mechanical property: �b �850mpa, �s�670mpa, δ�5%, ��30%. the two1:6(1:12) taper hole rolling treatments are checked by ring gage. Its contact area has continuous distribution on the circumference. The contact area is not less than 75% .the line of intersection of all cylindrical surface of the hull are facetted obtuse angle by hand or grinding wheel , forming a circumference r�8.test pressure is 49mpa, keep pressure 1 hour, pressure can not be reduced. Finished products have crack detection report.

We are offering piston assy bonded replacement. Among these are: � pistons with replacement rubbers our premium pistons are fully interchangeable with other api standard designed pistons and deliver maximum performance in almost all drilling conditions. High tensile strength, resistance to chemicals, hydrocarbons, and abrasion, long lasting service, and full interchangeability with other api designed pistons make our premium piston a sound value. � bonded rubber pistons this one piece bonded constructed piston has no joints to leak. Eliminates abrasive fluids between piston and liner. The fluid expanded lip is not damaged by high pressure and fast pump strokes. this fail-safe piston seals off to greater diameter as liner wears � premium bonded urethane pistons currently running in pumps using exotic muds and highest drilling pressures! bonded construction - no joints, no leakage. Longer piston and liner life. This piston will run in higher-pressure, fast stroking pumps, and is resistant to oil base muds and other additives currently being used. This premium piston has been in service for years, providing unmatched performance under extreme drilling conditions. This one piece bonded unit provides the same series of advantages., being imprevious to oil and other chemicals.

We are offering valve seat. 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. 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. stem-guided valve & cross-arm seat features an extra wide metal to metal seal on the valve flange.

Innovative unibody valve design eliminates snap rings, plates or keepers providing reduced maintenance by snap-on valve inserts and easy installation. hna makes two styles 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 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.
