THE ACCESSORIES OF PUMP
Modules:All the drilling mud pump modules aremanufactured by high quality alloy steel AIS18620 or AISI 4135.Heat treatment and internal hardened for highdurability.With strictly mechanical machine,and NDT,itcould serve a long wear performance.All our products aredesigned under 5000psi,7500 psi,and 10000 psi pressure.
Liners:Bi-metal liners with high abrasion and corrosionresistance are used.The liner sleeve is made of wearresisting cast iron.The surface hardness of the liner sleeve isHRC 60 to 65.ceramic liners are made of a forged steel outershell and a ceramic inner sleeve.
Valve Assembly:stem-guided valve &cross/three-arms seat ,wings-guided valve/full open seat
Piston:the piston is sealed by the rubber O-ring along withthe cylindrical surface fit and then is tightened by lock nuts,preventing the piston from looseness and acting as thesealing.
