Internal Gear Pump QXP
Metering pump for polyurethane production

The QXP is an internal gear pump for metering isocyanates, polyols, additives and other fluids. Combined with a variable-speed drive, the QXP is being applied very successfully as a metering pump in the production of polyurethane.

Advantages

• precision metering with very low pulsations, even at high pressures.

• can be used with high and low viscosities, and with variable-speed drives.
