Power end: The shell is of welding structure made of steel plates, and internal stress is eliminated afterwelding. The power end drive gear is a transmission gear, witch runs smoothly with high efficiency and a long service time. Crankshaft is a hollow one piece casting. Power end is splash lubrication.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.
