New gear pump motor options

The established range of HNP positive displacement, internal gear pumps has been expanded to include new, larger pumps and more drive options to suit a wider range of applications. Available from pump specialists Michael Smith Engineers, the HNP 11500 Series provides a performance output of flows between 0.2 and 1150mL/min and differential pressures between 0-60 bar or 0-150 bar, depending on the viscosity of the process fluid.

Three motor options are available, AC, DC and an ATEX rated explosion proof AC motor version, suitable for use in a hazardous areas.

Tungsten carbide rotors and bearings along with other hard construction materials, such as ceramics, ensure long service life and high levels of wear resistance, even when transferring non-lubricating liquids.
