Marine Engine Cooling Pump

Jabsco 43210-0001

The Jabsco 43210-0001 is a bronze Flexible Impeller engine cooling pump with a Neoprene Impeller, Lip Type seal, 1-1/4 Inch Hose Barb Ports, bare shafted pump only. The Jabsco pump Model 43210-0001 is a direct replacement for the Quicksilver pump Model 46-72774 A32 used on MerCruiser inboard and stern drive engines. It can be installed with either the cast iron (clamp type) mounting bracket or the stamped steel (bolt attachment type) mounting bracket. It will fit either left-hand or right-hand rotation engines and will accept all stock MerCruiser drive pulleys. The pump ports accept the standard 1-1/4 Inch ID hoses. This pump is self-Priming and pumps instantly, with dry suction lifts up to 10 feet (3m); up to 25 feet (8m) when wetted. Permits cleaner, safer installations. No foot valve required. Be sure suction lines are airtight or pump will not self-prime. This unit depends on liquid pumped for lubrication. Do Not Run Dry for more than 30 seconds. Lack of liquid will damage the impeller and the pump components.

This pump is an engine cooling water pump for Mercruiser engines. replaces Quicksilver model 4672774 A32. This flexible impeller pump combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugals. It will pump either thin or viscous liquids and can handle more solids in suspension than other types of rotary pumps. It operates at low or high speeds can be mounted at any angle and pumps in either direction with equal efficiency. This pump has one moving part a tough, longlived, wearresistant flexible impeller lubricated by the liquid being pumped. No metaltometal pumping action no gears to jam, clog or become noisy. Flexible impeller pumps, in general, require less SPACE because they deliver greater flow for weight, size and price than other types of pumps.

Jabsco 50410-1201

The Jabsco 50410-1201 is a bronze Flexible Impeller engine cooling pump with a Neoprene Impeller, Full Cam, Buna N Lip Seal, 1-1/4 Inch Hose Barb Ports. This pump is designed to mount directly inside the crank-shaft pulley on Chevrolet small block (305 and 350 C.I.), and 454 C.I. Chevrolet Block engines. The pump may be operated in either rotational direction. The maximum recommended pump speed (engine speed) is 5200 RPM. The maximum recommended discharge pressure should not exceed 10 PSI. When the pump is installed so it operates at or near maximum speed, the inlet plumbing must be designed to minimize the vacuum at the pump inlet. 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. Typical discharge pressure is 12 15 PSI, and discharge pressure should not exceed 20 PSI (138 kPa) as 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.

Be sure that the intake system is free from obstructions and the discharge system has less than 10 PSI pressure.

This is a Crank Pulley Mounted Drive Engine Cooling Pump specially developed for high speed operation on petrol and diesel engines, and fitted with a rotating bearing housing bolted directly to the crankshaft pulley, thus eliminating mounting brackets, belts and pulleys. As the pump body is supported by the ball bearing only, it must be prevented from rotating by means of a torque arm, designed and installed so as to avoid any side load on the bearing. This Jabsco flexible impeller pump combines the priming feature of positive displacement type pumps with the general transfer ability of centrifugals. It will pump either thin or viscous liquids and can handle more solids in suspension than other types of rotary pumps. It operates at low or high speeds can be mounted at any angle and pumps in either direction with equal efficiency.
