    NRV Series Rotary Vane Vacuum Pump

    NRV Series – Rotary Vane Vacuum Pumps

    $844.68$22,693.15

    NRV pumps are a line of oil circulated rotary vane vacuum pumps, perfect for smaller applications. The pumps function by utilizing the sealing features of oil around the pump chamber to seal incoming gases between a series of vanes on its rotor. A key characteristic here are the vanes that are pushed against the pump chamber by springs or hydraulic pressure. The vanes move in and out of the rotor during operation of the pump. The oil is spread around the pump chamber by the vanes, and this completes the seal of the pump chamber.
