Welcome to buy roots vacuum pump from fengyuan,which is one of the best roots vacuum pump ,roots blower manufacturers and suppliers in China.

Brief introduction of roots vacuum pump :

Roots vacuum pump (roots-type pump) is a non-compression of the vacuum pump, usually very low compression ratio, so high, medium-vacuum pump need to pump.

Pumping chamber by a pair of leaf-shaped rotor synchronous, reverse rotation of the push to move the gas to achieve the vacuum pump exhaust

**Characteristics of Roots vacuum pump:

1.The roots vacuum pump has a larger pumping speed within a wide range of pressure.

2.with a bypass relief valve can be activated at atmospheric pressure, reducing the pumping time.

3.there are gaps between the rotor, the rotor and the pump cavity wall ,between the pump moving parts without friction, no lubrication, the pump cavity without oil.

4. rotor shape symmetry, good dynamic balance performance, smooth operation, select the high-precision gear drive, low noise operation

5.compact structure, small footprint, usually selected horizontal structure, the vertical flow of gas within the pump chamber, which will be pumped dust or condensate removal

6.operation and maintenance costs low.

**Parameter of roots vacuum pump:

**Characteristics of Roots vacuum pump :

1.start fast, 

2.less power consumption, 

3.low operation and maintenance costs, 

4.pumping speed, high efficiency,
