External lubricating oil pump

● Purpose

External lubrication slag oil pump is suitable for conveying lubricating oil or other liquids with properties similar to lubricating oil, which does not contain solid particles and fibers, is non corrosive, has a temperature not exceeding 180 ℃, and a viscosity of 5 × 10-6~1.5 × 10-3m2/s (5-1500cSt).

● Application scope

The external lubricating oil pump can be used as a transmission and booster pump in oil transportation systems;

Can be used as a fuel pump for delivery, pressurization, and injection in the fuel system;

A hydraulic pump that can be used to provide hydraulic power in hydraulic transmission systems;

In industry, it can be used as a lubricating oil pump;

● Structural characteristics

This series of external lubricating oil pumps mainly consists of gears, shafts, pump bodies, relief valves, and shaft end seals. The gears have high hardness and strength after heat treatment, and are installed together with the shaft in a replaceable shaft sleeve for operation. The lubrication of all parts inside the pump is automatically achieved using the output medium during pump operation.

There are oil discharge and return grooves inside the pump, which cause the gear to bear less torque force during operation, resulting in less bearing load and less wear on the pump.

The pump is equipped with an overflow valve as overload protection. The total reflux pressure of the overflow valve is 1.5 times the rated discharge pressure of the pump, and can also be adjusted according to actual needs within the allowable discharge pressure range. However, please note that this relief valve cannot be used as a pressure reducing valve for long-term operation. If necessary, it can be installed separately on the pipeline.

From the extended end of the spindle towards the pump, it rotates clockwise.
