PLUMBING CONNECTIONS
Pump ports have external 1" hose barb and internal 1/2"
pipe threads. Also provided are two male port adapters
to allow the attachment of 3/4" female garden hose
fittings. Use hose that does not kink when bent and with
sufficient wall thickness to prevent collapse when used
on suction side of pump. Hoses should be routed so that
some water will be retained in pump body to wet the
impeller. Wetting the impeller aids in priming and
extends impeller life. Useastrainer on the intake hose to
stop trash and solids from going through the pump. All
hoses must have airtight connections to enable faster
priming.

APPLICATION
Use for bilge pumping, livewell circulation, washdown
and general pumping requirements. For intermittent duty,
motor may be reversed to empty bait tank.
Pump has a dry prime suction lift of about 6 feet (2m) and
a lift to 20 feet (6m) when primed. BE SURE SUCTION
LINES ARE AIRTIGHT.
INSTALLATION
The pump must be mounted inadry location—the motor
is not waterproof and must not be submerged.
SELECTION OF A COOL VENTILATED location will gen-
erally extend pump motor life. The unit can be mounted in
any desired position. It is best to mount so that water
dripping from loose port connection will not wet the
motor. The pump head may be rotated 180° on the motor
to change the direction of flow.
Model 18670-Series
Explosion Hazard. Do not pump gasoline, solvents, thinners
or other flammable liquids. To do so can cause an explosion
resulting in injury or death.
WARNING
!
Explosion Hazard. Do not operate with rivets removed from
motor case. Explosion resulting in personal injury, death or
property damage can occur. Case openings must be sealed
to avoid explosion and maintain ignition protected rating.
