The established range of HNP positive displacement, internal-gear pumps has been expanded to include new, larger pumps and more drive options. The 11500 Series (photo) deliver output flows of 0.2–1,150 mL/min and differential pressures between 0–60 or 0–150 bar, depending on the viscosity of the process fluid. Three motor options are available: a.c., d.c. and an ATEX-rated, explosion-proof a.c. version for hazardous areas. — Michael Smith Engineers Ltd., Woking, U.K.
