Internal Gear Pumps QXV
(for low-viscosity fluids)

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
