1 Structure Features
1.1 Power End Features
a) The Frame The frame is made of welded steel plate and stress relief treated to obtain the good rigidity and high strength. The place where the crankshaft bearing is fitted is strengthened by using ribbed plates. The frame is furnished with the necessary oil basin and oil way system for 

cooling and lubricating purpose.
b) The Pinion Shaft The 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. The both ends of the pinion shaft extend out, so that the sheave or the sprocket can be mounted on either end.
c) The Crankshaft The crankshaft is made of cast alloy steel and furnished with herringbone gear, connecting rod and bearing. The tooth form of the big-geared ring is herringbone gear. The gear bore and the crankshaft surfaces are 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.
d) The Crosshead And Crosshead Guide The crosshead and crosshead guide are made of homebred meehanite cast iron featured by good abrasion resistance and long service life. Upper and lower guides are used for mud pump, so that the concentricity can be adjusted by adding shims beneath the lower guide. The connection between the crosshead and the extension rod is made by using bolted flange. 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 light-weight coupling enables the extension rod and the piston rod to connect to each other easily and reliably.
e) The Extension Rod Packing The extension rod packing is duplex seal structure to provide the good seal result.
f) The Power End The power end uses the combined lubricating system of forced lubrication and splash lubrication.

1.2 Fluid End Features
a) 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.
b) Discharge pulsation dampener, shear relief valve and discharge strainer are furnished at the outlet. F-1300 and F-1600 pump suction inlet is furnished with Φ305 flange.
c) Valve Assembly The suction valve and the discharge valve for F-1300 and F-1600 mud pumps are interchangeable. 
F-1300 and F-1600 mud pump uses API 7#valve pots.
d) Liners Bi-metal liners are used. The sleeve is made of wear-resistant cast iron, the surface hardness is HRC60~65. Therefore, liners feature wear resistance, corrosion resistance and high surface finish. Liners are put in from the liner chamber in the front of the frame and fixed with liner thread ring , liner lock ,bolt and wear plate when installing.
e) 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 pot covers, thread rings and cylinder heads at the fluid end of F-1300 and F-1600 mud pumps are all interchangeable.
f) Spraying System The spraying system consists mainly of spray pump, cooling water box, and spray pipe, the function is to cool and rinse liners and pistons to promote their service life. The centrifugal spray pump can be driven by a sheave mounted on the input shaft extension end or a separate motor and cooled and lubricated by water. The durable fixed spray pipe is used. The spray pipe is mounted on the liner end cover and the frame. Nozzle is face to the piston end so that the lubricatingcooling fluid can rinse the contact surface between the piston and liner all the time.
g) Lubricating System The power end uses the combined lubricating system of Charles Rig Supplies, Inc. forced lubrication and splash lubrication. The pressure oil is conveyed through lubricating pipeline, crosshead, extension rod, crosshead guide and all bearings by a gear oil pump within the oil box to realize the forced lubrication. The working condition of the gear oil pump may be understood from the pressure gauge behind the frame.
h) Charging System To prevent the air lock occurring for low pump inlet pressure, every mud pump should be furnished with a complete charging system. It consists of charging pump,pump base, butterfly valve and corresponding manifold. Mounted on the suction manifold of the mud pump, the charging pump is driven by the special purpose motor or the input shaft of the mud pump through V-belts to reduce the power consumption.
