Liquid Ring Vacuum Pump
Medium Capacity, Vectra GL

The NASH Vectra liquid ring vacuum pump and compressor series delivers optimum performance with unprecedented production efficiencies. The Vectra GL models, with capacity ranging from 115 to 830 ACFM (195 to 1,400 m3/h), are engineered to deliver outstanding reliability and performance for general industrial applications.

Reliable and Efficient with Proven Performance

Based on proven reliable NASH conical liquid ring pump designs, the Vectra series delivers superior performance and reliability through several engineering upgrades.

  • Built-in mechanical seals eliminate shaft leakage
  • Improved cone angles, which decrease the size of the pump,
  • Patented Gas Scavenging Technology dramatically improves pump performance at high vacuum levels

Easy to Maintain – Low Total Cost of Ownership

The Vectra GL pump was engineered to be easy to maintain, with improvements that optimize performance and reliability.

  • Bearings placed outboard where they can be accessed without disassembly of the pump.
  • Pump body is engineered to reduce forces on the pump shaft
  • Lobe purges reduce erosion wear

Operates as a vacuum pump and compressor with a discharge pressure range of 15 psig (2 bar abs.)

Some applications require vacuum and compression in one process. Instead of handling the gas with two separate machines, our liquid ring vacuum pump and compressor models can do the job with only one pump – reducing cost and simplifying installation.

Reliable and Efficient with Conical Porting and Rotor Configuration

Patented in 1932, Nash’s variable conical porting design allows the force of compression to counter the weight of the rotor and shaft to help minimize load on bearings during operation. The variable porting optimizes pump performance across the entire operating range. With constant innovation, Nash’s patented design features:

  • Option for lobe purge to minimize damage from erosion in duties with solids present
  • Large differential pressure capability
  • Gas scavenging feature minimizes slip of gas from discharge to inlet improving capacity, especially at deep vacuum
  • High liquid carryover tolerance
  • Side discharge to minimize the chance of flooded start
  • Self-priming design may allow the elimination of booster pump in recirculated systems
