Ultra-compact Gear Pumps

The range of HNP positive displacement, internal gear pumps from Michael Smith Engineers, has been expanded with the HNP 11500 series, providing a performance output of flows between 0.2 to 1150 ml/min and differential pressures between 0-60 Bar or 0-150 Bar, depending on the viscosity of the process fluid. There are 3 available motor versions: AC, DC and an ATEX rated explosion proof AC motor. Tungsten carbide rotors and bearings along with other hard construction materials, such as ceramics, ensure long service life and excellent wear resistance of these motors, even when transferring non-lubricating liquids. These high performance HNP pumps are ideally suited to a wide range of liquids transfer duties in chemical processing, pharmaceutical and industrial applications.

Designed to deliver smooth, precise pulse-less flows (CV < 1% at low volumes) with high differential pressures, these rotary pumps feature an externally toothed internal rotor and an annular tooth external rotor. These are slightly eccentric to each other and during rotation of the rotors around their offset axis, the pumping chambers simultaneously increase on the suction side and decrease on the delivery side of the pump. This results in a homogeneous flow rate being generated between the kidney-shaped inlet and outlet. It is this design principle, combined with careful materials selection and high manufacturing precision, which facilitates the transfer of very low volumes with precise, smooth, pulse-less flows.
