Applications

Features • Rugged corrosion resistant bronze construction • Compact closecoupled design • Stainless steel shafts • Durable bronze helical gears provide quiet operation • Process lubricated carbon graphite bearings • Oring cover seal for maximum leak protection • Easy field assembly to a variety of motor frames • For bronze pedestal pumps and mechanical seal styles see model N2000 • For closecoupled ductile iron pumps see model C992 Applications These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild chemicals in the pH range 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 from 32 F to 140 F for best pump life. If more extreme temperature conditions exist, 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. SUCTION LIFT As a general rule, the suction lift should be kept at an absolute minimum by placing the pump as close to the liquid source as possible. A gear pump in new condition can lift 20 feet of water in the suction line. A foot valve preferably with builtin strainer is recommended at the beginning of the suction line. For a first startup, the pump should be primed to avoid dry running. MInimum size of the suction pipe is the size of the pump inlet port. For longer suction lines over 3 feet or for viscous liquids, the pipe should be at least one size or two sizes larger than the pump inlet port.
