AUTOVENT™ breather
seals dirt and moisture
out while allowing the
gear case to breathe
during startup and cool

QUADRILIP™ shaft seal
system – consists of 2 spring
compression lips, 1 trash
guard lip and 1 collector
grease pack – keeps
contaminants out and
lubricant inside the gear case .
Shaft material is wear resistant, high carbon
steel that provides
stable non-grooving
surface for oil seal
contact.
Standard paint has 316
stainless steel flakes with a
flexible and tough resin
binder. USDA incidental
contact H1 approval provides excellent moisture and
corrosion resistance.
Primer paint covers all
exterior surfaces of the
housing, providing
excellent base corrosion
protection.
Outside diameter of oil
seals is nitrile rubber. Direct
connection of seal to housing
eliminates bolt-on covers and
centers the seal, eliminating
the potential for leakage.
UNICASE™ one-piece housing
is torsionally stiff, machined in
one pass, has extreme accuracy,

Please consult factory for additional information.
SELECTING THE CORRECT NORD REDUCER OR GEARMOTOR
1. Determine the actual horsepower or kW requirements of
the application from the pump performance curve, which
can be electronically generated with the Viking Pump
Selector Program, located on www.vikingpump.com,
or specifications from other equipment.
2. Based on the horsepower or kW requirement,
go to the closest higher HP or kW page.
Example:
For a 7.1 HP requirement, go to the 7.5 HP catalog page.
Then find the reducer which most closely matches your
speed requirements.
a. Reducer: 510 RPM output speed, solid input shaft.
