Figure B−2. 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.
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.
Field Wiring Connections (Incoming Power)
The pump is designed to operate with a 115 volt,
1 phase, 60 hertz power supply. The voltage avail-
able at the motor must be within the indicated
range in Table B−3.
