Oberdorfer - 305M-08 Flexible Impeller Pump - 8 GPM @ 2 psi- 6 lbs weight - Mechanical Seal Type

Oberdorfer 305M-08

These Flexible Impeller pumps are made of high quality bronze of maximum corrosion resistance. All shafts consist of stainless steel grade 303. Top of the line models have ball bearings and mechanical seals while others have bronze or carbon bearings and lip type seals. Impellers are made of Neoprene Rubber. Nitrile impellers are available as an option. Flexible blades on the periphery of the impeller provide the pumping action. While the impeller rotates the liquid between the blades is continuously squeezed out into the discharge port by a machined in cam located inside the pump chamber. Pump will operate when mounted in any position.

Liquids and Temperatures 

Liquids compatible with neoprene can be pumped including fresh and salt water solutions and mild chemicals. Do not pump severe solvents or acids. When possible flush pump with fresh water after each use.

Extremes of cold and heat will affect impeller life. Limits of 40°F to 180°F should be observed. Do not allow liquid in pump to freeze. Drain pump by loosening cover screws. Use methyl alcohol based anti-freeze compounds such as Zerex, Shell Zone, Pyro Permagard, or Dowgard.

Drive 

The pump is driven directly from the electric motor shaft. An aluminum adapter connects the pump to the motor. Reversing supply leads to motor terminals reverses motor rotation. “In” and “Out” pump ports are also reversed.

Suction Lift

Suction lift of 15 feet is possible when impeller is wet. Suction lines must be air tight in order for pump to self prime. A foot valve at the beginning of suction line is recommended.
