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.
