Roots vacuum pump is mainly composed of rotor, pump body, cooler, etc. The rotor rotates 120 degrees in the pump chamber and completes the process of suction and exhaust.The cooling gas enters the suction chamber of the pump from both sides of the pump body, so that the pump will not overheat due to the compressed gas, but there is no impact on the pumping performance of the pump.Extraction efficiency, noise, vibration and other performance than the traditional two - lobe roots pump significantly improved.
The rotor of air-cooled pump adopts the linear structure of involute, which has no contact and keeps constant clearance when rotating.Due to the special patented structure, the air-cooled pump can operate reliably under high pressure difference and high compression ratio for a long time, which can be used alone or in series with multiple units, or with other vacuum pumps to achieve higher vacuum to meet all kinds of process requirements.
Main Feature:
● when used alone, the working vacuum degree of in-line air can reach 150mbar.
● multi-stage series or with other front pump pump series can reach the vacuum range.
● special patent structure to ensure that the pump in high pressure difference and high compression ratio operation will not overheat overload.
● three-leaf involute line structure and high precision machining to ensure smooth and quiet product operation.
● the advanced balanced mechanical seal makes the sealing performance of the pump more reliable than the traditional skeleton seal.
● roots vacuum pump cavity for no oil groove, suitable for the extraction of general air and a variety of special gases.
