It is composed of motor, pump sleeve, end shell, rotor and rotor elastomer. The pump sleeve and end lining are made of high quality steel. The rotor is wear-resistant non-metallic material, which makes all the friction contact surfaces of the pump highly wear-resistant. Therefore, the pump is very wear-resistant, firm and durable, and has a long service life. Both radial and directional design are equipped with automatic gap compensation mechanism, which has the function of automatic gap compensation. After wear and tear, the parts are durable and maintain a high vacuum for a long time. The design structure is unique, even if rotated in the opposite direction, the parts will not be damaged. Even if not used for a long time, the re-start can be flexibly started as usual. The pumping flow rate can be from very small as 1 liter per minute to 50 liters per minute; the suction distance can be from 2 meters to more than 9 meters; and the lift can be up to 20 meters.

1. Oil pumps are suitable for transporting various oils, such as heavy oil, diesel oil and lubricating oil. Copper gears can be used to transport low-point liquids, such as gasoline and benzene. The unit also produces stainless steel gear pumps for transporting beverages and corrosive liquids.

2. The oil pump can also be applied to those containing hard particles or fibers, and to various viscosities. Temperature can be as high as 300 C. If you need to transport high temperature liquid, please use high temperature resistant gear pump, which can transport liquid below 300 C.

3. Various pump types of oil pump are simple and compact, easy to use and maintain, and have good self-priming property. It helps not to inject liquid before starting each pump.

4. The lubrication of some oil pumps is automatically achieved by transporting liquid, so no additional lubricant is needed in daily work.

5. The use of elastic coupling to transfer power can compensate for the small deviation caused by the installation of the oil pump. When the pump is inevitably impacted by hydraulic pressure, it can play a better buffer role.
