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 with 1 1/2” NPT standard pipe
male thread. All suction connections must be air tight to
achieve lift.
PUMP OUTLET
3/4” external garden hose thread with 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.

MOTOR
12 volt D.C. high torque, 18 amps. Intermittent duty
cycle. Do not run pump dry. 24V and 32V also available.
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.
To replace the impeller, remove screws and cover. Remove
macerator wheel, plate and gaskets. 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 flat on impeller with flat on 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 slinger 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.
