LIQUIDS AND TEMPERATURE
Liquids compatible with neoprene can be pumped including fresh
and salt water solutions and mild chemicals. Do not pump severe solvents
or acids. When possible, flush pump with fresh water after each usage.
Buna N impellers can handle oil contaminated water and kerosene at
reduced impeller service life.
Extremes of cold and heat will affect impeller life. Limits of 40o to
140o 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.

PUMP INLET
2” slip-on hose section or 1 1/2” NPT standard pipe
thread. All suction connections must be air tight to achieve
lift.
PUMP OUTLET
3/4” external garden hose thread or 3/8” NPT standard
pipe thread internal.
MACERATOR
Will handle sewage, waste, toilet paper, cigarettes,
cigars and all maceratable solids of approximately 1 inch
size.
Will not handle fruit pits, hard plastic utensils, prophylactics, cloth or fabric sanitary napkins.
MOTOR
12 volt D.C. high torque, 18 amps. Intermittent duty
cycle. Do not run pump dry.
SUCTION AND DISCHARGE
Self priming up to 4 ft. Up to 20 ft. uphill discharge or
up to 50 ft. away. (Use large diameter garden hose - 3/4” for best results.) A 30 gallon holding tank can be emptied in
less than 4 minutes.

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.
IMPELLER REPLACEMENT
The impeller must be replaced if it is worn out or has been damaged
by debris or by running the pump dry. Symptoms of a defective impeller are
low pumping pressure and low flow causing overheating of the boat
engine. Poor pump performance can also be caused by slippage of Vbelts, so belts should be checked for tightness.
To replace the impeller remove screws and cover. Pull out the
impeller with nose pliers or two screwdrivers. Be careful not to dent the
pumping chamber with these tools. When inserting new impeller, line up
key slot in impeller with the key in the shaft. Use oil on shaft and avoid forcing the impeller onto the shaft.
The impeller should also be removed for storage periods to prevent
the blades from taking a permanent set.
SEAL REPLACEMENT
If water drips from the weep hole or from the area where the shaft
exits the pump, the seal is defective and must be replaced. While the
Teflon®* barrier seal provides a first line of defense, prolonged running of
the pump with a leaky seal can destroy the ball bearings resulting in catastrophic pump failure and engine shut-down.
For seal replacement, the pump must be removed from the engine
and disassembled in order to gain access to the seal area. Where
mechanical seals are used, both components (stationary and rotating
member) must be replaced at the same time. Lip seals must be pushed out
of their press-fitted position and new seals pressed into place, using a
sealant on the outside of the lip seal housing.
Refer to exploded view drawings for seal location and part numbers
for ordering purposes.
