S SERIES PUMPS
PAGE B - 4
INSTALLATION
All liquid entering the pump must pass through a
strainer screen. Any spherical solids which pass
through the screen will pass through the pump.

Piping
No suction piping is required in a standard installa
tion.
S Series pumps are provided with a suction strain
er to prevent large solids from clogging the impel
ler. On some models the strainer can be removed
and the pump suction “staged” to the discharge of
another pump, allowing one pump to feed the oth
er on high discharge head applications.
To determine the size of the discharge connection,
see
Table B-1, Pump Specifications
. Either
hose or rigid pipe may be used. To facilitate mobil
ity and maintenance, it is recommended that the
discharge line be fitted with a quick disconnect fit
ting near the pump. The discharge line must be in
dependently supported to avoid strain and vibra
tion on the pump.
Either hose or rigid pipe may be used to make dis
charge connections. For maximum pumping ca
pacity, keep the line as short and straight as pos
sible. Elbows and fittings used in discharge lines
increase friction loss, minimize their use.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control si
phoning or back flow when the pump is shut off.
ELECTRICAL CONNECTIONS
Install and operate this pump in accor
dance with the National Electrical Code
and all local codes. Have a qualified
electrician perform all checks and con
nections in this section.
Never attempt to alter the length of the
pump motor cable or to repair it with a
splice. The power cable and pump mo
tor must be kept completely waterproof.
