rotary vane vacuum pump for sale

Rotary vane vacuum pump is a kind of varactor mechanical vacuum pump, which utilizes the rotating motion of the rotor and the vane sliding in the rotor slot to obtain vacuum. When the working fluid is used to lubricate and fill the dead gap of the pump chamber, separating the exhaust valve from the atmosphere, it is commonly known as the oil-sealed rotary vane vacuum pump.

When there is no working fluid, it is a dry rotary vane vacuum pump. In oil-sealed rotary vane vacuum pump, it is customarily called a rotary vane vacuum pump with belt drive in China, and a direct rotary vane vacuum pump with direct connection to motor or coupling is called a direct rotary vane vacuum pump.

In each pump, there are single and double stages. In single-stage pumps, the limit pressure and usage of pumps are different due to the different structure and parameters. Their common characteristics are simple structure, easy use, starting from atmospheric pressure, direct discharge of the atmosphere, small eccentric mass, simple maintenance, the limit pressure of two-stage pump is 6 *10-2~l *10-2 Pa, one single-stage pump can reach about 4 Pa, the other single-stage pump is about 50-200 Pa.
