oberdorfer oil change Gear pumps
HEAVY DUTY DC bronze GEAR PUMP
These Oberdorfer gear pumps come with a continuous duty
1
/
4
horsepower dc motor.
They will operate as an oil change or diesel transfer pump in single or reversible
operation (an in-line switch is required for reversible operation). They are available
in 12 and 24 vdc, will deliver up to 60 psi discharge pressure and will self-prime
to 20 feet when wet.
115 VAC REVERSIBLE bronze GEAR PUMP
Oberdorfer’s 115 vac reversible gear pump comes standard with a heavy-duty
TEFC
1
/
3
horsepower motor with integral reversing switch making oil change or
diesel transfer a snap. The new N993Q-F30 model is specifically designed for diesel
transfer (not for oil change) delivering up to seven gallons per minute in forward
or reverse operation.
COMPACT DC BRONZE GEAR PUMP
This compact oil change/diesel transfer pump by Oberdorfer utilizes the rugged
bronze gear pump design that will give years of dependable service. They are
available in 12, 24 and 32 vdc, will deliver up to 25 psi discharge pressure and
will self-prime to 20 feet when wet. Even though these pumps do not come with a
reversible switch, one can be mounted in-line to achieve reversible operation.
115 VAC “LOW RPM” bronze GEAR PUMP
These low rpm gear pumps are designed specifically for thick or cold oil operation.
The lower revolutions per minute (1140 rpm) allow more viscous oils to move
through the pump with less opportunity for cavitation (the leading cause of oil
change pump failure).
