Applications

Features • Bronze Construction with Stainless Steel Shafts • Helical geras for quiet operation • Easy Field Assembly to Motors • SelfLubricating Carbon Bearings • Oring seal for maximum leak protection • For clutch driven version, see N97038 Applications These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild chemicals in the pHrange of 4 to 11. Viscous liquids require reduced shaft speeds of 1150 RPM or lower. Consult factory. Liquids containing solids, abrasives, powders or paint pigments are definitely not recommended for gear pumps. If abrasives are unavoidable, use a very low shaft speed. The recommended liquid temperature range is 32oF to 140oF for longest pump life. If more extreme temperature conditions exist, our factory should be consulted. Freezing of waterfilled pumps can cause damage and must be avoided. Oils at low temperatures are very viscous requiring a lower speed or extra power.
