Figure B−1 Typical Pump Installations
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.
Serious damage to the pump and injury
or death to personnel can result from
any alteration to the cable.
