a?? 1. Power end
a?? continuous tooth herringbone gear. One-piece alloy steel crank. Renewable crosshead guide. The frame is made of welded steel plate to provide the frame with strength, good rigidity and lightweight. The extension rod packing is of duplex seal structure to provide the good seal result. The power end uses the combined lubrication system of forced lubrication and splash lubrication.
a?? 2. Crankshaft
a?? the crankshaft is made of cast alloy steel and is furnished with big-geared ring, connecting rod and bearing. The tooth form of the big-geared ring is herringbone gear. The gear bore and the crankshaft surface is interference fitted and they are both fastened with bolts and lock nuts. The big end of the connecting rod is mounted on three eccentric straps of the crankshaft through single row short cylindrical roller bearings and the small end on the crosshead pin through double row long cylindrical roller bearing. Double row radial spherical roller bearings are mounted at both ends of the crankshaft.
a?? 3. Cylinders
a?? cylinders are made of forged alloy steel. Three cylinders of each pump are interchangeable. Valve-over-valve (through type cylinder) design reduces the cylinder volume and promotes the volumetric efficiency. At customers' request. The cylinder surface may be nickel plated to improve the abrasion resistance.

F-1000 single acting triplex mud pumps are authorized by Continental Emsco Company to manufacture in China and fully conform to Continental Emsco Company"s technical requirement.
F-1000 mud pumps are rated at longer stroke length and relatively low stroke per minute. It can increase the service life of expendable parts of fluid end assembly.
The fluid end assembly mainly consists of fluid end, valve assembly, liners and pistons. Fluid end is made of forged alloy steel and three fluid ends of each pump are interchangeable. The suction valve and discharge valve of F mud pump are interchangeable. Liners use Bi metal, the sleeve is made of wear resisting cast iron. Piston and piton rod are of slide fit and sealed with rubber seal rings and are fastened with lock nuts to prevent the piston from loosing.
The valve seat bores have bottom shoulders. The piston and liners are spray lubricated and cooled which allow an extended service life.
