Features of rotary vane vacuum pumps

A coarse filter with wire mesh is installed at the suction port of the vacuum pump. It can prevent solid foreign dust particles from being sucked into the pump chamber. An exhaust transition device with high-efficiency oil-gas separation effect is installed in the oil separator. When the pump is stopped, the suction valve built into the suction port isolates the pump from the pumped system and prevents oil from returning to the pumped system. The pump is cooled by air. All XD rotary vane vacuum pumps are driven by direct motors through elastic couplings.
