Suction hoses must be rigid enough not to collapse. Make sure the
suction hose is in good condition. A hole or tear in the suction hose
above the water line will prevent the pump from priming.
NOTICE: Always use a strainer on the end of the suction hose to
prevent pulling in large debris which could clog the pump or jam the
impeller.
Discharge hoses are usually thin-walled collapsible hoses; however,
rigid hoses like those used on the suction side can also be used.
Lay the discharge hose as straight as possible. Avoid sharp bends and
turns.
Note: Both suction and discharge hoses are available through Wacker
Corporation.
A variety of couplings are available to attach the hoses to the suction
and discharge ports as well as to connect two hose lengths together.
Suction Hose to Inlet Port Coupling
At least two T-bolt clamps are recommended for connection of the
suction hose to the pump inlet. Index clamps at 90° intervals for best
seal. Add additional clamps if the pump has trouble priming.
Note: The smallest air leak on the suction side of the pump will prevent
the pump from priming.
Other hose connections
Normally only one T-bolt or worm gear clamp is required to hold the
hoses in place. In some cases, variances in hose diameters may make
it necessary to add extra clamps to maintain a reliable connection.
