The single stage series of the single-stroke oil-rotating-vane vacuum pumps and the two stage series of the double stroke oil-rotating vane vacuum pumps are the equipment for obtaining vacuum by pumping the gases from sealed containers, especially suitable for the pumping work for cold producing maintenance (for the vacuum pumping with R12, R22, or R134a as cold-producing medium), medical appliances printing machinery, vacuum packing, gas-analysis and hot-forming plastics. And they can also be used as the fore-stroke pumps of all kinds of high-vacuum equipment.
