Product Description

The single lobe roots vacuum pumps have been designed for use in pump sets in combination with a rotary vane backing vacuum pump. The working principle of roots vacuum pumps or vacuum boosters is similar to the rotary vane pumps. Through the inlet (A) air enters a conveying cell formed by the two rolling pistons (C, D) in the housing. The cell is then separated from the inlet by the following piston head (F). The air in the cell (E) is conveyed without reduction until it reaches the outlet (B), where air with a higher absolute pressure flows from the pressure chamber into the following cell, and must then be discharged. Some models are equipped with an automatic bypass valve (G) that limits the pressure differential between inlet and outlet.
The Roots blower pump is a staple of high capacity vacuum systems where they are used as a "booster pump" for quickly evacuating large chambers.
Features & Highlights
There is zero friction between rotors, also between rotor and pump chamber, so there is no need of lubricating oil.
Consequently, our pump can avoid the oil pollution on vacuum system.
Compact structure,
Easy to install horizontally or vertically
Good dynamic balance,
Stable running,
Lower vibration and lower noise
Can pump off the non-condensable gas
Quick started and can achieve the utmost pressure in a short time
Small power and low operation maintain costs
The bypass value on roots pump can enjoy the automatic overload protection effect, so that the operation will be safe and reliable
