recommended. Recommended pipe submergences for various flows as well as recommended bell diameters
are shown in the table below. The table data is referenced from ANSI/HI 9.8-1998.
7.
Attach a flexible hose to the outlet (discharge) side of the pump. Make sure the O-ring seal is present in the
fitting on the pump before attaching the fitting.
Note:
Lubricate the O-ring seal with grease to ensure an airtight seal.
8.
Use a concentric taper on the discharge side to increase discharge pipe/hose diameters. All valving and additional
fittings should be the same size as the discharge main-line. The discharge size should be adequate to maintain
reasonable velocities and reduce friction losses. It is strongly recommended that a pressure relief valve is installed
on the discharge piping.
9.
Check the intake and outlet hoses for any sharp bends or kinks that may restrict pump flow before proceeding.
The intake hose should slope upwards toward the pump to avoid development of air pockets in the hose, which
may lead to pump cavitation. Keep the hoses as straight as possible.
WARNING
Do not attempt to operate the pump unless all connecting piping, fill plug, and other
fittings are securely installed. Failure to do so could cause liquid pumped to be forced
out under pressure, causing injury to personnel.
10. The pump is self-priming but should never be operated unless there is liquid in the pump casing. The pump
casing needs to be half filled with liquid in order to prime. Remove the cover from the top of the pump volute and
fill the pump casing with water. The pump will not prime when dry. Extended operation of a dry pump will destroy
the seal assembly. Make sure pump casing is half filled with liquid when priming.
Note:
The casing will only fill to the bottom of the intake
fitting, not to the top of the volute. Replace the cover and
tighten the clamp screws hand tight.
WARNING
Never open the priming cover on a
pump that is hot or that has been
operated recently. Extreme pressure
may have built up inside the pump
volute. Opening the priming cover
could cause serious injury.
The pump is now ready for use.
