Liquid ring vacuum pumps

Advantages

  • High-quality, reliable pumps which are suitable for many industrial applications.
  • Great variety of graded pump sizes which span a large range of delivery volumes
  • Broad portfolio of different designs: Robust standard designs, pumps that are free of dead space, pumps suitable for delivery of water shares, operating water-saving pumps and low-noise, two-stage pumps

Description

  • Single-stage and two-stage pumps, with and without flap valves
  • Close-coupled pumps and base plate pumps
  • Mechanical seals, depending on the medium
  • Usually with a single mechanical seal, but also available with a double-acting mechanical seal
  • VZ model series also with a magnetic coupling
  • Various material designs: Copper alloy, grey cast iron and stainless steel
  • Base plate pumps with type examination certificate and ATEX (II 1G IIB+H2 cbk TX)
  • Close-coupled pumps with ATEX II 2G cb TX
