Applications
There are many applications that the Oberdorfer 172B are used in. Typical applications are Marine Air Conditioning, Engine Block Temperature Control, Radiator and Heat Exchanger Circulation Baitwell Circulation, as well as circulation applications such as hot and cold water systems, windscreen washing, livewell and bait tank systems and liquid transfer. These circulation pumps can be used in low pressure circulation applications such as marine central heating systems where they can be used to circulate heated coolant water heater from an engines recirculating fresh water system through radiators in the vessel living spaces. One of the outstanding features of this pump and motor unit is its compact size. Although small, adequate motor power is available for pumping water, water solutions, and a wide range of commercial chemicals. Viscous liquids with a maximum viscosity of 2000 Saybolt Seconds Universal can be pumped. However, when pumping viscous liquids as compared with water a reduction in flow and pressure occurs and the required horsepower increases. Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity. To connect the pump to piping use 3/4 inch pipe fittings with PTFE pipe joint tape or compound.
