NDRV Series – Dry Running Rotary Vane Vacuum Pumps – Small Capacity
NES Company proudly introduces our NDRV dry-running single-stage compact rotary vane vacuum pump series. The series comes in capacities from 4-17 CFM and vacuum levels up to 27” Hg. The carbon vanes are designed for a smooth replacement process and are built sturdy. The dry running feature of the pump minimizes environmental impact by voiding the risk of oil contamination of process gasses and waste gas discharge. All of this leads us at NES Company Inc. to confidently state that this pump series is built with the future in mind.
NRV Series – Rotary Vane Vacuum Pumps
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.
