The Biggest Discount! Oilfield API F-series Mud Pumps, New Product

A1. Power End 
 Power end features:
.Continuous tooth herringbone gear.
.The crankshaft is made by alloy steel.
.Changeable crosshead guide.
.The frame is made of welded steel plate to provide the frame with high strength, good rigidity and light weight.
.The extension rod packing is duplex seal structure to provide the good seal result.
.The power end uses the combined lubricating system of forced lubrication and splash lubrication.
A2. Fluid End 
Fluid end features:
.Each sealing part abopts rigidity compaction and has good high pressure tightness;
.Vertical fluid end features good suction performance;
.L fluid end features high pressure resistance,convenient for replacing the valve assembly ;
.Discharge damper ,shear relief valve and discharge filter are fitted at the discharge outlet.
1.Cylinders
Cylinders are made of forged alloy steel, three cylinders of each pump are interchangeable. At customers're-quest, the cylinder surface may be nickel plated to improve the abrasion resistance. 
2.Valve Assembly
The suction valve and the dischange valve for F-series mud pumps are interchangeable. F-500 mud pump uses API#5 valve. F-800 and F-1000 mud pumps use API#6 valve. F-1300 , F-1600, F-1600Land F-1600HL mud pumps use API#7 valve. F-2200Land F-2200HL mud pumps use API#8 valve .
3.Liners 
Bi-metal liners are used. The sleeve is made of wear-resistant cast iron,liners feature wear resistance, corrosion resistance.
F-1600HL and F-2200HL mud pumps can choose ceramic liners in order to improve service life.
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.
5. plunger 
Fluid end, liners, pistons, valves, valve seats, valve springs, seal rings and gasket ,valve cover and cylinder head of fluid end assembly for F-800 and F-1000 mud pumps are interchangeable.
Fluid end assemblies of  F-1300 and F-1600 mud pump are interchangeable. Fluid end assemblies of  F-1300HL and F-1600HL mud pump are interchangeable, too.
A3.Spraying System
The spraying system consists mainly of spray pump, cooling water box, and spray pipe, the function is to cool and flush liners and pistons to improve 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 spray pipe is mounted on the coupling between the extension rod and the piston rod and can reciprocate with the piston. Nozzles is near the piston end so that the lubricating-cooling fluid can rinse the contact surface between the piston and liner all the time. The durable fixed spray pipe may be used, too.
A4.Lubricating System
The power end uses the combined lubricating system of forced lubrication ad splash lubrication. The pressure oil is conveyed through lubricating pipeline, crosshead, Intermediate rod 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.
A5.Charging System
To prevent the air lock occurring for low pump inlet pressure, every mud pump is 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.
