QXV Internal Gear Pumps

Description

Pumps Low-viscosity fluids

The QXV series has been developed for use with low-viscosity fluids. QXV pumps have proven particularly successful in applications for pumping kerosene, automotive fuels, paraffin, brake fluids and many other low-viscosity fluids. When required, a multi-stage pressure build-up can be employed to achieve high pressures of up to 250 bar with a viscosity close to 1 mm2/s, and with high efficiencies at the same time.

Advantages

  • For open circuits up to 250 bar max. working pressure
  • For low-viscosity fluids from 0.8 mm2/s to 10 mm2/s
  • High temperatures up to 160 °C are possible
  • Available in EX-proof versions EX II 3 G T3 and T4
  • Can be used with variable-speed drives
