HQX Series – Self-Priming Gas/Liquid Pump

The HQX is a versatile range of self-priming pumps that can mix ultra-fine air bubbles (20-30 µm) by simultaneously intaking low-viscosity liquid and gas, pressurising and mixing the two.

The HQX’s 304 stainless steel construction and maximum operating temperature of 120°C make them suitable for a variety of applications, with ATEX-approved explosion proof models for fuel handling.
