Internal Gear Pumps QXV (for low-viscosity fluids)

Description

The QVX is an internal gear pump for low viscosity. It can develope pressures of 300 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

  • Very low noise levels
  • 300 bar can be developed
  • Outstanding efficiencies
  • Long service life
  • Low pump wear
  • Low sceptibility to cavitation
  • Good emergency running
