The SS233 submersible pump is designed to pump water
and is used for the draining (de-watering) of flooded
rooms, drains and fill tanks, power fountains and waterfalls
swimming pool covers, and flat roofs.
A plastic impeller is attached to the output shaft of a 1/2 HP
electric motor which provides adequate power for general
purpose pumping. This submersible pump is supplied
complete with an electric power cable, and a discharge port
located at the top of the pump which accepts a 2-inch hose.
This pump is ideal for portability because of its light weight
and carrying handle. In addition this pump will pump dry
to 1 inch. Built in overload protection protects the electric
motor from overheating.
The pump, when in use, should be installed as free standing
(upright position) on its strainer base. A 2-inch discharge
hose (not supplied) should be connected to the discharge
port located on top of the pump. The discharge hose should
be adequately supported to avoid stress on the pump.
For maximum water flow, the discharge hose should be
kept as short as possible and with minimum elevation
above the pump. Remember, as the length and/or height
of the discharge hose is increased, the flow of water will
be reduced. Also, any reduction in the hose size and any
fittings such as valves or outlet nozzles will restrict the
water flow.
To avoid back-siphonage when the pump is switched off,
ensure that the end of the discharge hose is installed above
the water level at the final discharge point.
When the pump is switched off, the water remaining in the
hose will run back through the pump. This can be avoided
by placing a non-return valve in the hose nearest the pump.
never use this submersible pump to pump flammable
liquids or operate in a explosive or flammable environment.
Avoid using this pump in conditions where mud, grit, silt
or other debris are present. These conditions could cause
blockage and cause excessive pump wear.
do noT install the pump directly into an area where there
is a heavy build-up of mud, grit, silt or debris. If this condition
is present, install the pump on a platform before operating.
This pump must always be positioned on a platform in an
upright position. never operate the pump by a suspended
rope. To prevent large solids from entering the pump, install
a wire mesh screen or similar barrier around the pump.
If the pump was used to pump water containing mud, silt,
use clean water to flush out the pump after each use.
do noT allow the pump to run dry, as this will damage the
pump. During maintenance, dry running is permissible but
only for a few seconds.
never lift the pump by its electrical power cord. alWaYS
lift the pump by its carrying handle or attached a rope to
carrying handle.
A fully submerged pump in liquid will not freeze, unless
the liquid freezes. do noT allow a partially submerged
pump to freeze. The expansion of water freezing in the
volute may crack the pump, causing expensive repairs. If
there is any danger of the pump being subjected to freezing
temperatures, Lift the pump from water and allow it to drain
thoroughly.
If the pump jams or the pump rotor locks for any reason,
disconnect the pump from the power source immediately.
Allowing the pump motor to cycle ON and OFF under an
overload condition can burn out the motor.
When replacement of nuts and bolts is required, use only
recommended parts as referenced in the parts section of
this manual. This pump uses metric threads. do noT use
english measurement threads.
