We can produce the piston cup, it strengthened the spot to use the nylon to strengthen, clamps the cloth to strengthen, these two kinds strengthened the way to be able to satisfy in the pump pressure ≤ 18MPa, in the temperature ≤ 60'c situation used, otherwise the service life will reduce greatly.

The piston cup which in view of high-pressured mud pump liners and the ceramic cylinder jacket and so on F-1600HL, F-2200HL produces, it strengthens the spot to use the import high polymer material compound suppression to become, can the good absorption impact, and guaranteed in ≥ 30MPa the situation, is not easy to tear, causes the piston unit the service life compared to domestic similar products long 3-5 times, achieves the domestic and foreign advanced standards.
