2. F series mud pump has a long stroke, which can be used at a low stroke number to effectively improve the water-loading performance of the mud pump and prolong the life of vulnerable parts at the hydraulic end.Advanced structure of suction air bag, reliable use, mud pump can achieve the best suction effect.
3. F series pump cylinder, crankshaft, herringbone gear and other important parts are made of high-quality alloy steel, the frame is welded with plates, high strength, good rigidity, light weight.
4. F series mud pump has high interchangeability. All vulnerable parts at the hydraulic end are interchangeable with parts of the same specification and model that meet the requirements of API specification.

Fluid end: the suction valve and the discharge valve conform to ASA and API specifications. It adopts clamp connection between the piston rod and the intermediate rod.
Damageable pieces have strong currency.
The valve seat bores have a bottom shoulders to prevent the sinking of the valve seat. The pistons and cylinder sleeves are spray lubricated and cooled, which allow an extended service life.
