ROTATION
Direction of shaft rotation determines inlet and outlet ports
(see line drawing)
MOUNTING
Pump will operate satisfactorily when mounted in any position. DO
NOT RUN DRY. Rubber impellers generate high rubbing friction unless
lubricated by liquid pumped. Lack of liquid will cause impeller to burn up.
DRIVE
Either direct drive with flexible coupling or pulley drive can be
used. Make sure both flexible coupling halves are properly aligned.
When using pulley, do not overtighten belt.
LIQUIDS AND TEMPERATURE
501-07 SAE B FLANGE MOUNT
Liquids compatible with neoprene (05) can be pumped including fresh and salt water solutions and mild chemicals. Do not pump
severe solvents or acids. Buna (06) impellers can handle oil contaminated water. When possible, flush pump with fresh water after
each usage.
Extremes of cold and heat will affect impeller life. Limits of 40o
o
to 140 F should be observed. Do not allow liquid in pump to freeze.
Drain pump by loosening cover screws. Use methyl alcohol based
anti-freeze compounds such as Zerex®, Shell Zone®, Pyro
Permanent®, Permagard®, Dowgard®.
SUCTION LIFT
Suction lift of 15 feet is possible when impeller is wet. Suction
lines must be air tight in order for pump to self prime. A foot valve at
beginning of suction line is recommended.
