Internal Gear Pumps QXV (for low-viscosity fluids)
Description
The QVX is an internal gear pump for low viscosity. It can develop pressures of 300 bar with high efficiency at viscosities of around 1 mm²/s. The QXV is being 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 susceptability to cavitation
- - good emergency running
