We manufacture and specialize in the fluid end parts of triplex mud pumps as per API standard for our clients all over the world. Fluid End includes cylinders, valve assembly, liners and pistons. 1.Cylinders 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. Discharge pulsation dampener, shear relief valve and discharge strainer are furnished at the outlet. F-500 pump suction inlet is fitted with 8"flange, F-500 pump suction inlet with 10"flange and F-1000 pump suction inlet with 12"flange. 2.Valve Assembly The suction valve and the discharge valve for the above three mud pumps are interchangeable. F-500 mud pump uses API#5 valve pot, F-800 and F-1000 mud pumps use API#6 valve pots. 3.Liners Bi-metal liners are used. The sleeve is made of wear-resistant cast iron, and the surface hardness is HRC60-65. Therefore, liners feature wear resistance, corrosion resistance and high surface finish. Liners are put in from the cylinder cover bore in the front of the cylinder and fixed with liner cage, cylinder cover plug and cylinder cover when installing. 4.Pistons and Piston Rods They are slide fitted, sealed with rubber seal ring and finally fastened with lock nuts to prevent the piston from looseness and to play a role in sealing. Cylinders, liners, pistons, valves, valve seats, valve springs, seal rings, valve covers and cylinder covers at the fluid end of F-800 and F-1000 mud pumps are all interchangeable.

mud pump		 We manufacture and offer power end parts of triplex mud pumps for our clients all over the world. Power End includes frame, pinion shaft, crankshaft, crosshead and extension rod. 1.Power end features 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 high 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. 2.Frame： The frame is made of welded steel plate and by stress relief treatment to obtain good rigidity and high strength. Ribbed plates are used to strengthen the place where the crankshaft bearing is fitted. The frame is furnished with the necessary oil basin and oil way system for cooling and lubricating purpose. 3.Crankshaft 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. 4.Pinion shaft Pinion shaft is made of forged alloy steel on which a herringbone gear with the medium-hard tooth surface is machined. For easy maintenance, the single row radial long cylindrical roller bearing with inner ring (without sides) is used. Both ends of the pinion shaft extend out, so that the sheave or the sprocket can be mounted on either end. 5.Crosshead and Extension Rod The crosshead and crosshead guide are made of ASTM A48-83 meehanite cast iron featured by good abrasion resistance and long service life. Upper and lower guides are used on F-800 and F-1000 mud pumps, so that the concentricity can be adjusted by adding shims beneath the lower guide. F-500 mud pump is the cylindrical structure. Bolted flange is used at the connection between the crosshead and the extension rod. The rigid connection ensures the concentricity of the crosshead and the extension rod. The coupling is used for connecting the extension rod to the piston rod. The lightweight coupling enables the extension rod and the piston rod to connect to each other easily and reliably.
