FEATURES
• Bronze Corrosion Resistant Castings
• Stainless Steel Shafts & Fasteners
• Self-Lubricating Carbon Bearings
• Packing (Braided Acrylic yarn with special lubricant and Graphite)
• Optional Viton Lip Seal
• For Mechanical Seals, see Models N13HDM
DRIVE
Either direct drive with flexible coupling or pulley drive can be
used. For pulley driven pumps a pillow block bearing must be used
at the drive shaft end to absorb the belt forces. The drive shaft is sufficiently long enough to accommodate a pillow block in addition to
the pulley.
Correct alignment is absolutely essential for satisfactory pump
life. Recheck alignment after the piping has been connected to the
pump.
LIQUIDS AND TEMPERATURE
Service life will be increased substantially if the liquid pumped is
clean and has a lubricity value. These pumps have extremely close
tolerances. Fine abrasives like sand, silt, or powders in suspension
will destroy pumping ability.
Liquids compatible with bronze, stainless steel and the acrylic
graphite packing can be pumped. Optional S5 Viton lip seal has
teflon backup and stainless case. Solvent resistant packings and
Teflon® packings are also available. See a chemical compatibility
table or check factory. When possible, flush the pump with water
after using.
Temperature extremes are detrimental to service life and should
be avoided. Basic metals of construction allow temperature range of
-40°F to 400° F. the acrylic graphite packing is rated to 500°F, the
Viton lip seal is rated to 300°F. Freezing liquid in the pump can
deform or damage the pump.

Note: Dotted lines(---) recommended for intermittent duty only
due to accelerated wear at higher speeds and pressures.
Viscous liquids such as molasses or oils require a lower pumping speed,
in extreme cases as low as 200 R.P.M. Consult factory for recommended
speeds and increased horsepower requirements. Large suction lines are
required to prevent cavitation which can cause pump destruction.
Liquids with specific gravities heavier than water such as dry cleaning
fluids require an increase in motor horsepower directly proportional to the
increase in specific gravity over water.
SUCTION LIFT
A rotary gear pump is capable of lifting water on the suction side as high
as 20 feet. Though gear pumps are self-priming, a foot valve is recommended. For pumping water directly from streams or ponds, a wire mesh
strainer must be used at the beginning of the suction line to prevent stones
from entering the pump. Strainer and foot valve are commercially available
as combination units.
