SEAL
The lip seal is Buna N with a stainless steel spring reinforcement on a stainless steel motor shaft. The seal is friction
press fit in machined housing counterbore. Excessive system
pressures above 15 p.s.i. are not recommended as the seal
could be forced out of pump housing.
LIQUIDS
One of the outstanding features of this pump and motor
unit is its compact D.C. motor size. Although small in size,
adequate motor power is available for pumping water, water
solutions, and a wide range of commercial chemicals.
Questions as to the chemical compatibility of special liquids
should be referred to the factory.
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.

CHARACTERISTICS
Oberdorfer centrifugal pumps have a single rotating impeller.
Liquid enters at the center and is thrown outward radially by centrifugal force. The impeller is not in contact with other pump parts
resulting in quiet, efficient pumping action. The flow produced is not
positive which permits the discharge line to be shut off completely
without danger of overloading motors or bursting lines.
Consequently, a relief valve is not required.
The pump uses a mechanical type shaft seal with a Buna
rubber element. It is suitable for water, oils, and some mild solvents
and is limited to 212o F.
These centrifugal pumps are not self-priming. They must be
installed below the liquid level so that the liquid flows to the pump
by gravity (flooded suction). However, if a foot valve is used at the
beginning of the suction line, and all air is bled from the pump by
manual priming, the pump will lift on the suction side up to 15 feet.
Such a system relies entirely on the non-leaking foot valve for starting capability.
The flow of a centrifugal pump can be conveniently controlled
by a throttling valve in the discharge line without the need for a
relief valve. In centrifugal pumps, the horsepower demand will
decrease as the pressure increases. Maximum horsepower occurs
with a wide open discharge.
