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 32 F to 140 F 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.
