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.
