Product Details

Polyurethane piston

The piston assembly is the main component of the hydraulic end of the mud pump, and the discharge pressure of the mud pump is generated by the reciprocating linear motion of the piston assembly in the cylinder liner. Small piston - high pressure, low flow rate; Large piston - low pressure, high flow rate. Metric pumps and English pumps correspond to the use of metric and English pistons. Generally, commonly used parameters include diameter 170, diameter 160, diameter 150, as well as 6 ", 6-1/2", and 7 ". The pistons of metric pumps F800, F1000, F1300, and F1600 are universal, and the inner hole of F500 piston is smaller than that of other types of pistons. The pistons of the British pump F500-F1600 are fully universal. The inner hole of the F500 piston in the metric pump is diameter 25.4; The inner hole of F800-1300 piston is diameter 42, while the inner hole of British piston is diameter 38.1. Material: piston core 42CrMo; Rubber, nitrile rubber or polyurethane.
