Applications
There are many applications that the Oberdorfer 750BP are used in. This pump is designed for continuous lowpressure circulation and transfer of nonflammable liquids, utility, boiler feed, general transfer, filtration, cooling towers, condensate return, marine applications, fountains, boosters, water circulation, irrigation, spraying systems, jockey pump service, chemical processing, aggressive liquid applications and other generalpurpose pumping compatible with Bronze and BUNAN pump component materials where suction lift or selfpriming is required. The special pump alloys used in this pump provide corrosion resistance to many liquids including 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 rate increases. Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity. Liquids contaminated with small solids or abrasives can be handled, but a reduction in mechanical seal life must be expected. This pump will pump continuously, producing high flow rates under lowhead conditions.
