Pump Placement - Storm Surge SS20T Manual Del Operador

5. Pull the switch wires through the panel and reconnect to
the switch terminals.
6. Remove the rubber grommet from the hole in the
engine shroud. Store the grommet in a safe location for
installation later.
7. Align the switch base with the hole in the engine fan
housing and press in place.
8. Follow normal engine starting procedures.

PUMP PLACEMENT

Proper Placement of Pump in Field (SEE FIGURE 4.)
NOTE: This pump is designed to be self-priming when
installed and operated as specified below.
• Make sure the pump is positioned on a flat, level, and
sturdy surface. The surface must support the weight
of the pump.
• Place the pump as close to the level of the water to be
pumped.
• Use the shortest hoses possible. Hoses that are too
long will decrease the pump flow output and increase
the time to prime the pump.
• When total head increases, the pump output
decreases.
• Discharge head capacity is greater than intake
(suction) head capacity. To achieve the correct
capacities, the pumping height of the intake hose
must be shorter than the pumping height of the
discharge hose.
• The intake hose and strainer must be immersed in
water when the pump is operating.
NOTE: Operation of your Storm Surge Water Pump
without an intake strainer basket will void your
warranty. The intake strainer has been designed
to prevent large debris from entering the pump
intake which can cause damage.
• The intake strainer basket should rest on stones or in
a bucket and be secured to prevent movement when
operating.
• Route the discharge hose to a suitable location.
Additional discharge hoses can be used but should be
kept to a minimum to ensure efficient operation.
Water Pump Terminology
Cavitation
• A condition that causes vacuum pockets to form
in the pump. When the air pockets explode under
pressure, pitting to the impeller and volute surfaces
can occur.

HEAD
WATER PUMP
• The total head, including static head and friction
head, on the discharge side of the pump.
• A damaging condition that occurs when a column
of liquid changes direction quickly and increases in
velocity. Weakest point in system will break. Causes
can be sudden loss of power to the driver, valve
closing too quickly, valve closing too slowly allowing
backflow.
• The total head on the suction side of the pump,
including suction lift and friction head.
• The total pressure or head the pump must develop
on the discharge side. It is the sum of THE ELEVATION,
THE SERVICE PRESSURE, and THE FRICTION LOSS. Of
course, all of these measurements must be expressed
in the same units, usually feet of head, before adding
them together.
• The shock wave or series of waves caused by the
resistance of inertia to an abrupt change of water
flow through a water piping system. Water hammer
may produce an instantaneous pressure many times
greater than the normal pressure. For this reason,
many building codes now require the installation of
a "water hammer arrestor" or accumulation device
to absorb shock waves and prevent damage to
appliances such as washing machines as well as
water treatment components such as reverse osmosis
membranes.
