DRV series two stage rotary vane vacuum pump is a type of oil-sealed pump that uses two stages of compression to achieve a high level of vacuum. The pump consists of two stages, each with a rotor and vanes that move in and out of the rotor slots. The first stage compresses the gas and the second stage further compresses the gas, resulting in a high vacuum level.

This specific model of two stage rotary vane vacuum pumps has a pumping speed ranging from 3 m3/h to 16 m3/h, depending on the model. The pump is designed to be compact and efficient, with low noise and vibration levels. It is made of high-quality materials, including a cast iron body and fiberglass vanes, to ensure durability and reliability.
