Product Description
Hydraulic cylinder is also called the valve box, it is a major part to the fluid end parts. Blank forged by highstrength alloy steel. After heat treated, with multi-channel processes. The three cylinders of each pump is interchangeable. The following key parts: cone sawtooth thread of cylinder head, connect of the curve of all the screw hole and inner cavity.
We can supply various mud pump expendable parts, including power end assembly, fluid end assembly and its spare parts, which can be easily matched & exchanged with some international famous mud pump brand, such as parts for 3NB series Pump, F series Pump, PZ series Pump, HBRS Pump, BOMCO Pump, EMSCO Pump, NOV P Series Pump, IDECO Pump, etc.
