 Product Details

Air-cooled Roots vacuum pump uses external cooler to automatically circulate the gas to cool the rotor and pump body. The pump can work continuously under high pressure difference without thermal overload, and the pump can directly discharge the atmosphere. The pump has many advantages of ordinary Roots vacuum pump. It can be used in series with the front pump or separately.
When the pump is used alone, the low-temperature air from the exhaust outlet can be directly used to return to the pump for cooling without using the cooler. The maximum pressure of about 130 hPa can be obtained for the large pump.
When the pump is combined with the Roots vacuum pump itself or ordinary labor, it can give full play to the advantages of Roots vacuum pump oil-free steam pollution to the pumped system. The pump can also be connected in series with the liquid ring pump, slide valve pump and other front-stage pumps to form a unit, which can obtain a large pumping speed close to the main pump pumping speed in the high pressure range. These two combinations can obtain different vacuum degrees in the range of 105Pa to 5*10-2Pa.
Because of the above characteristics, this type of pump is widely used in situations where the permission pressure is not high and the need for rapid pumping is relatively large, or where the need for clean and oil-free vacuum pumping is needed.
