SELF-PRIMING PUMPS FEATURES Body: Impeller: Shaft: Wear Plate: Shaft Seal: Bearings: Ports: Weight: Bronze Neoprene, Nitrile Stainless Steel Replaceable Lip Type Sealed Ball Bearing 1/4" NPT Internal 1-1/2 lb (0.7 kg) approx. Neoprene Impeller Nitrile Impeller APPLICATIONS 3. SPEEDS - 100 RPM to the maximum shown in the performance table. Consult the factory for operation at speeds above those shown. For longer pump life, operate at lowest possible speeds. 4. SELF-PRIMING - Primes at low or high speeds. For vertical dry suction lift of 10 feet, a minimum of 800 RPM is required. Pump will produce suction lift up to 22 feet when wetted. BE SURE SUCTION LINES ARE AIRTIGHT OR PUMP WILL NOT SELF-PRIME. 5. RUNNING DRY - Unit depends on liquid pumped for lubrication. CAU TION Do not run dry for more than 30 seconds. Lack of liquid will damage the impeller. 6. NOTICE - If pumping light fraction petroleum derivatives, solvents, thinners, highly concentrated or organic acids, consult Jabsco Chemical Resistance Table (which is available upon request from ITT Jabsco) for proper body materials and impeller compounds. If corrosives fluids are handled, pump life will be prolonged if pump is flushed with water after each use or after each work day. 7. PRESSURES - Consult Head Capacity Table for recommended maximum for continuous operation. It pressures exceed those shown, consult the factory. 8. TEMPERATURES - Neoprene 45°–180°F (7°–82°C), Nitrile 50°–118°F (10°–82°C). 9. FREEZING WEATHER - Drain unit by loosening end cover. 10. GASKET - Use a standard pump part. Thicker gasket will reduce priming ability. A thinner gasket will cause the impeller to bind. Standard gasket is 0.010" thick. 11. SPARE PARTS - To avoid costly shut downs, keep a JABSCO Service Kit on hand. MARINE: Engine cooling, Pumping bilges, Washdowns, Circulating water in bait tanks. INDUSTRIAL: Circulating and transferring, Velocity-mixing, Pumping machine tool coolants, Return spill, Sump drainage, Chemicals, Pharmaceuticals, Soap, Liquors, Ink, Dyes, Alcohol, Various acids, Tanning liquors, Glycerine, Brine. OPERATING INSTRUCTIONS 1. INSTALLATION - Pump may be mounted in any position. Intake and discharge ports are determined by the direction of shaft rotation (refer to Dimensional Drawing). Before installing, turn the pump shaft in the direction of the operating rotation, 2. DRIVE - Belt or Direct with flexible coupling. BELT DRIVE - Overtight belt load will reduce bearing life. DIRECT DRIVE - Clearance should be left between drive shaft and pump shaft when installing coupling. Always mount and align pump and drive shaft before tightening the coupling set screw. NOTICE: If drive pulley or coupling must be pressed on shaft, remove end cover and impeller and support shaft from impeller end during press operation. Do not hammer a pulley or coupling on shaft. Failure to follow above instructions can damage the pump. TOTAL HEAD 500 RPM P.S.I. Ft.of Water GPM (kg/sq cm) (metre) (LPM) HP NOTE: Progressively longer life may be expected as operating pressures and speeds are reduced. Factory Application Engineering assistance suggested for operation in light shaded area and recommended for heavy shaded area. Capacitor type motor recommended. Table shows approximate Head-Row for new pump in U.S. gallon

SERVICE INSTRUCTIONS EXPLODED VIEW Impeller Replacement: Remove end cover screws, end cover and gasket.Grasp impeller hub with water pump pliers and pull straight out of body. Lubricate impeller bore.Once started, line up impeller screw with slot in shaft and push impeller straight into body. Lubricate face of impeller, install gasket, end cover, and secure with end cover screws. Major Repair: Follow steps outlined above to remove impeller. Remove outer bearing seal, remove bearing to body retaining ring. Pressing on impeller end of shaft, remove shaft and bearing assembly. Remove inner...
