Rotary vane vacuum pumps offer a simple design that ensures the reliability, and the durability required in the vacuum industry. The compact designs offer an efficient use of installation space and easy maintenance.

NES Company, Inc. offers the NRV series single-stage, oil-filled rotary vane vacuum pumps. These rotary vane vacuum pumps circulate oil as a lubricant and sealant around their inner chamber to allow up to 0.5 mbar for medium to high vacuum applications such as degassing, chemical processing, filtration and reactor vacuum. The NRV Series provides consistent and reliable vacuum performance and operation in various applications, operating quietly with low noise and low vibration for optimal stability. These rotary vane vacuum pumps are designed as functional replacements to Busch R5 RA rotary vane units to save space with a compact structure that is operator-friendly for installation, maintenance, and repair.

The NDRV series of dry running single-stage rotary vane vacuum pumps are a functional replacement for Becker dry -running vane units. They are perfect for small-capacity clean applications such as vacuum packaging, printing, medical instruments, resign de-gassing, molding, filtration and venting. They use carbon composite vanes for self-lubricative properties, generating up to 27” HgV in vacuum from 4 to 17 CFM flow capacity. The NDRV Series boasts a compact and simple design for low noise, low vibration, and easy internal access, all of which translate to a safe, stable, and easily maintainable pump.
