Description:
1. 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. Generally, f170, f160, f150 and 6?, 6-1/2?, 7?, etc., is used.
2. Metric pumps can generally adopt F800, F1000, F1300 and F1600 pistons. The inner hole of F500 piston is smaller than that of other models. The inner hole of F500 piston of the metric pump isf25.4; The inner hole of F800--1300 piston isf42. The inner hole of inch piston isf38.1.
3. Inch pump can generally adopt F500--F1600 pistons.
4. Material: piston core 42CrMo; Rubber sheet: Buna-N rubber or polyurethane
