Large pumping speed durable Low noise DRV rotary vane air pump vacuum pump
The DRV series vacuum pump is a double stage rotary vane oil-sealed vacuum pumpsuitable for low and medium vacuum applications, mainly used to remove air and other dry gases. It is one of the main equipment for low and medium vacuum, it can be used alone or as a fore
pump of other vacuum pumps.
The vacuum pump has the characteris-tics of reliable running performance, less wearing parts, low vibration, low noise and high efficiency.
The SV series vacuum pump is imported from foreign advanced technology, and the key com- ponents are imported components or imported
materials. The DRV series vacuum pump can completely replace similar foreign products.
