Jabsco # 2570-3100 Marine Engine Cooling Pump

The Jabsco 2570-3100 is a bronze Flexible Impeller engine cooling pump with a Neoprene Impeller. This is a Marine Engine Cooling Pump for Detroit Diesel Marine Engines and is the Detroit Diesel part # 23507971. This pump is self-priming, and will self-prime at low or high speeds. It will pump instantly, with dry suction lifts of up to 3m (10 feet), and up to 8m (25 feet) when wetted. This permits cleaner, safer installations. Be sure suction lines are airtight or the pump will not self-prime. The intake vacuum suction pressure should not exceed 7 inches or mercury (178mm Hg), and discharge pressure should not exceed 20 PSI (138 kPa). Typical pressure 12 15 PSI, and excess discharge pressure may cause impeller damage. The Neoprene impeller in this pump depends on liquid pumped for lubrication. Do not run dry for more than thirty (30) seconds as lack of liquid will burn the impeller. This is a Gear Drive Engine Cooling Pump and the drive gear fitted to this heavy duty flange mount pump is supported by the pump ball bearings and driven by one of the engine gears.
