Mud pump spare parts Piston assembly for oil field
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 piston assembly is constituted by the piston core, rubber, spring, clamp, etc. Pistoncore is made of 42CrMo and the piston rubber is made of nitrile rubber or polyurethane rubber.
