EMSCO F- series Mud Pump Main Gear

Product Introduction

We can also supply below spare parts:


The crank shafts are alloy steel castings. Gears, connection rods and bearings are separately  mounted on the crank shaft. The teeth on the gears are herringbone teeth. The tight fitting is used for the assemble between inner hole of gears and crank shaft together with inserting bolt and locknut for solidification. The big end of rod is installed respectively on three eccentric elbow of the crank shaft by means of the single column roller bearing, while the small end is installed on the cross pin through the double column roller bearing. Both ends of the crank shaft are double column centripetal sphere roller bearing. 

Pinion shaft

The pinion shaft are alloy steel forgings assembling with manufactured herringbone teeth gear featured with medium-hardnessed teeth surface. For the convenience of maintenance, the single column centripetal long roller bearing is selected for the internal circle without cover edge. Either end of the shaft can be mounted with belt wheel or sprocket wheel.

Crosshead and extension rod

The materials of the crosshead and the crosshead guiding plate are of outstanding wearing resistance with long service life. By the adoption of upper and lower guiding plates, the concentricity is in a position to be adjusted by employing shims at the lower guiding plate. The crosshead and the intermediate rod are connected by flange bolt, with which rigid connection the concentricity between the rod and the crosshead can be guaranteed. Clamps in light weight are employed  for connection between extension rod and piston rod , which are convenient and reliable .


Hydraulic cylinder

Hydraulic cylinder is forged of alloy steel. Three cylinders of one pump are interchangeable with each other. According to customers special requirements, to enhance the anti-corrosion performance, the surface of the hydraulic cylinder is supposed to be processed with chemical plating nickel. Pulsation dampener , shear relief valve and discharge strainer are separately mounted on the outlet.

Valve assembly

The suction valves and discharge valves of RLF mud pump are interchangeable with each other.



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 cylinder cover bore in the front of the cylinder and fixed with liner cage, cylinder cover plug andcylinder cover when installing.

Spray pump

This system is consisted of spray pump, cooling water tank and spray pipelines with the function of the necessary cooling and splashing to liners and pistons to prolong their lifetime.


The splashing pump is the centrifugal pump which can be driven by the belt mounted on the end of input shaft, or can be individually driven by a motor with water as the cooling and lubrication media.


To wash the interface between the pistons and liners back and forth , the fixed spray pipelines are employed which are secured inside the shell.


Lubrication system

he combination of forced lubrication and splashing lubrication is used for the power end. For the purpose of forced lubrication, the gear oil pump located at  the oil tank feeds compressed oil to crossheads, extension rods and bearings respectively via the lubrication pipe lines. More ever, the operation situation of the gear oil pump can be observed by the manometer embedded in the after body of mud pumps.


Charging system

Each mud pump can be equipped with one charging pump to avoid air blocking caused by low pressure at the suction inlet. The spray  system is driven by a special motor which is installed on the suction pipe assembly. To reduce the total power supply of drilling rigs, driving shaft is employed to drive the  spray  pump  as well.
