Service life will be increased substantially if liquid
pumped is clean and has lubricity value. These pumps have
extremely close tolerance. Fine abrasives like sand, silt, or
powders in suspension will destroy pumping ability.
Liquids compatible with bronze, stainless steel, and a
Viton(R)* lip seal can be pumped. Check a chemical compatibility chart or Oberdorfer factory. Buna Lip Seal (S3) available.
Temperature extremes are detrimental to service life
and should be avoided. Temperature range for this pump is
from -40oF to 300o F. Freezing liquid in the pump can deform
or damage the pump.
SUCTION LIFT
A rotary gear pump is capable of lifting water on the suction side as high as 20 feet. Though gear pumps are selfpriming, a foot valve is recommended. If possible, wet gears
with the liquid to be pumped for the first dry start. Liquid
retained in the system and gear chambers serves to wet the
pump on subsequent starts.
ROTATION
The pump or pump/motor unit is supplied by the factory
for shaft rotation in either direction. Reversing the motor rotation will reverse the “in” and “out” ports.
To reverse single phase motors, find instructions on the
inside of junction box cover or on name plate of motor.
Three phase motors are not wired for any particular
rotation. They can be reversed by interchanging any 2 wires
of the 3 wire leads.
*Viton(R) or equivalent FKM will be used. Viton(R) is a registered
trademark of DuPont Dow Elastomers.

Basic pump model number N1100 must be matched to appropriate motor adapter kit listed as W, X, Y, Z kits as required by motor frame size.
The final model number is formed by adding codes together in a building block fashion.
Example: 1) Find pressure/flow, required HP, suggested motor frame size (see front) single or (3) phase.
ex: 35 [email protected] 50 PSI requires 2HP, 184TC frame motor
