| Message: | 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.
Working temperature -30 ° C ~ 80 ° C; applicable medium: oil-based mud, PH value 5-11; working pressure ≤ 37Mpa; Use life ≤ 400hours url:http://www.baohaopetroleum.com |
