Piston
Metric pump and imperial pump is corresponding to use of metric and imperial piston.Φ170,Φ160,Φ150 and 6〃,6-1/2〃,7〃 and the like are commonly used.Metric pump F800,F1000,F1300,F1600 pistons are common,F500 piston bore is smaller than the other piston models.
Imperial pump piston F500-F1600 are all universal.
Metric pump F500 piston bore is Φ25.4.F800-1300 piston bore is Φ42,imperial piston bore is Φ38.1.
Material: Piston core is forged by 45#/35 CrMo/42CrMo,rubber NBR or polyurethane.

Nitrile Rubber
Suitable for ordinary drilling environment with working pressure
below 20Mpa.Working temperature is not higher than 12°C.
Excellent wear resistance,chemical resistance and long service life.
Polyurethane Rubber
Outstanding oil resistance and wear resistance.Working temperature is not higher than 120°C.Suitable for oil-based mud and high sediment working environment under working pressure 35Mpa.
Hydrogenated Nitrile Rubber
Suitable for high temperature,high pressure and high corrosion working environment.
Working pressure 75Mpa.Working temperature up to 150°C.Hydrogenated nitrile rubber is widely used in aviation industry.For oil industry,it has high wear resistance,oil resistance and chemical resistance,also good amine resistance and steam resistance performance.
