Mud pump
Power end
1. The frame is a welded structure with steel plate, high strength, rigidity and light weight.
2. Adopting herringbone gear drive, running smoothly.
Fluid end
1. The hydraulic cylinder is straight pass-through structure, it can make the fluid flow smoothly, volumetric efficiency higher and structure compact.
2. The three hydraulic cylinders are interchangeable.
3. The cylinder head and valve pot cover can be rapidly tightened, convenient for assembly and teardown.
4. The suction valve and discharge valve can be interchanged
5. The piston and liner bore are open wide structure, convenient for observing.....
