Internal gear pump


The internal gear pumps of the V and VS SAXMAG® series have been designed for use under difficult working conditions and are used for pumping viscous liquids up to 100,000 mPa*s, which may also contain abrasive particles but no solids.

These are industrial applications where careful handling of the fluid is required to avoid changing its chemical and physical properties. VARISCO internal gear pumps ensure a pulsation-free flow rate that is proportional to the rotational speed and is reliably available regardless of back pressure.
