Liners combine the strength of a forged steel outer shell with the abrasion and corrosion reisistance of a high chromium iron inner sleeve.Feature a centrifugally cast high chrome iron sleeve which is machined and heat treated to a minmum uniform bore hardness of HRC65
The surface of the liners with a mirror-like smooth finish and the inner holes’ dimension tolerance is strictly controlled to ensure a long using life of more than 800 hours.Our liner made for superior performance under tough corrosive and abrasive conditions.We supply all common models of drilling rig mud pump liner in material zirconia ceramic and high chrome bimetal for Emsco, Gardner Denver, National, Oil well, Continental, Ideco, 3NB series mud pump and so on, ceramic liner inner sleeve material is 99.99% zirconia, high chrome bimetal liner is forgings , with chrome content 28%, HRC 65, next taking high-chrome liner for example

The piston rod is made of structural alloy steel, which goes through tempering heat treatment to achieve superior mechanical performance. The surface of the piston rod can be treated through phosphatization or galvanization.We can provide piston rods with various kinds of specifications of F series, 3NB series, PZ series, and others.There material of piston rod is 45# steel or 35GrMo. It’s used with piston together. And the size of core is included 1 5/8″ and 1 1/2”.
Piston rods are forged using alloy steel.the intension of products is improved after heat treatment. The surface of product is zincification,nickel-plate,and plating with decorating chrome.After numerical control processing,the products can meet various demands of clients.

Our 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 instal. PZ8 PZ9 PZ10 drilling mud pump parts bonded rubber piston sale 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.
Bonded Urethane Pistons Our bonded urethane pistons dramatically extend service life in triplex pumps with ample water cooling. Harder, more dense polyurethane construction provides superior resistance to abrasive fluids providing optimum service life in harsh drilling conditions. It is interchangeable with piston with replacement rubbers.
