Product catalog summary
Operation Instructions: Flexible impeller pumps should not be run dry as the pumped liquid lubricates the impeller. An automatic level switch is recommended to control the pump. The pump should not operate against a closed outlet, and normal operation pressure should not exceed 20 feet of head (8.7 psi). The temperature range for the pumped liquid is 45° - 180°F (7° - 82°C).
Self-Priming Pump Features: The pump features a permanent magnet motor, stainless steel shaft, and a bronze body. It includes a Jabsco Neoprene compound impeller and a lip-type seal. The motor meets USCG Electrical Standards and ISO 8846 MARINE for ignition protection.
Applications: Suitable for bilge pumping, livewell circulation, washdown, and general pumping. For bilge water with oil, replace the standard impeller with an oil-resistant nitrile impeller (No. 6303-0003). The pump has a dry prime suction lift of about 4 feet and a lift to 20 feet when primed.
Installation Guidelines: Mount the pump in a dry, cool, and ventilated location. The pump head can be rotated 180° to change flow direction. Ensure airtight suction lines for efficient priming.
Plumbing and Electrical Connections: Use hoses that do not kink and have sufficient wall thickness. Ensure airtight connections and use a strainer on the intake hose. Connect the black wire to the negative terminal and the orange wire to a fused switch or circuit breaker connected to the positive terminal.
Maintenance: Regularly check wires and connections for corrosion. If idle for long periods, the impeller may stick; clean and lubricate before reassembly. In freezing temperatures, drain the pump by loosening end cover screws.
Disassembly and Assembly: Detailed steps are provided for disassembling and assembling the pump, including lubrication and alignment instructions.
Warranty Information: Jabsco offers a one-year limited warranty covering defects in material and workmanship. The warranty excludes misuse, neglect, and unauthorized repairs.

SELF-PRIMING PUMP FEATURES Permanent magnet type, fully enclosed, stainless steel shaft. Jabsco Neoprene compound 1/2" Internal Pipe Threads 1" External Hose Barb Adapter for 3/4" External Garden Hose Thread included Motor meets USCG Electrical Standards 183.410 and ISO 8846 MARINE for IGNITION PROTECTION on gasoline powered vessels. ! Explosion hazard. Do not operate with rivets removed from motor case. Explosion resulting in personal injury, death or property damage can occur. Case openings must be sealed to avoid explosion and maintain ignition protected rating. OPERATION Flexible impeller pumps must NOT be run dry, as the pumped liquid is the lubricant for the impeller. Observe the outlet and shut off pump as soon as liquid stops flowing. An automatic level switch is convenient to control the pump. The pump cannot run against a closed outlet such as encountered when using a garden hose type shut-off nozzle. Pressure for normal operation should not exceed 20 feet of head (8.7 psi). Temperature of pumped liquid may be in the range of 45° - 180°F (7° - 82°C). APPLICATION Use for bilge pumping, livewell circulation, washdown and general pumping requirements. If bilge water contains significant amount of oil, the standard impeller should be replaced with impeller No. 6303-0003, which is an oil-resistant nitrile material. Pump has a dry prime suction lift of about 4 feet (1.2m) and a lift to 20 feet (6m) when primed. BE SURE SUCTION LINES ARE AIRTIGHT. Light housing gets hot during Motor runs hot—about 180° is a normal operation. Do not contact during temperature. Prolongedtouch during or immediately after operation. operation may cause a burn. Burns can res

INSTALLATION The pump must be mounted in a dry location - the motor is not waterproof and must not be submerged. SELECTION OF A COOL, VENTILATED location will generally extend pump motor life. The unit can be mounted in any desired position. It is best to mount so that water dripping from a loose port connection will not wet the motor. The pump head may be rotated 180° on the motor to change direction of flow. PLUMBING CONNECTIONS Pump ports have external 1" hose barb and internal 1/2" pipe threads. Also provided are two male port adapters to allow the attachment of 3/4" female garden hose fittings....

MAINTENANCE Check wires and connections to be sure corrosion is not adding additional resistance to the motor circuit and causing a low voltage condition at the motor. Low voltage can inhibit motor from starting and cause fuse to blow. Full voltage should be available to prevent motor damage. NOTICE: If pump is idle for extended periods, the impeller may stick to the pump body, preventing motor rotation and causing blown fuses. To correct, remove end cover and impeller, clean body and impeller, then lubricate with water or small amounts of grease before assembly. If pump is to be in freezing...
