Internal Gear Pumps QXV (for low-viscosity fluids)

Description

The QVX is an internal gear pump for low viscosity. It can develope pressures of 250 bar with high efficiency at viscosities of around 1 mm²/s. The QXV is beeing used with great success to pump aviation jet fuels, paraffin oil/kerosene, brake fluids, Pentosin and HFA fluids.

Advantages

  • 250 bar can be developed at viscosities around 1 mm2/s
  • Volumetric efficiency up to 98% by multi-stage principle
  • Temperatures up to 160°C are possible
  • Suitable for ATEX compliant explosion protection Ex II 3 G T3 and T4
  • Suitable for use with variable speed drivers
  • Low sceptibility to cavitation
  • Good emergency running
