Water Connection; Wiring And Grounding - Xylem Goulds e-SV Serie Manual De Instrucciones

For 1-22SV pumps using motor frame sizes 213TC
– 256TC, place adapter ring on top flange of motor
adapter. For 33-125SV pumps using motor frame
sizes 284TC – 286TC, motor frame sizes 213TC and
larger, attach the motor adapter flange to the motor
using 4 hex cap screws. Torque to values shown in
the "ENGINEERING DATA" section of this manual.
Loosen the 4 coupling socket head screws enough
to provide an adequate opening in the coupling to
receive the motor shaft.
With an adequately sized crane, carefully lower
the motor assembly onto the pump motor adapter
and into the coupling. Secure the 4 motor hex cap
screws, torquing to the value provided in the
"ENGINEERING DATA" section of this manual.
Torque the 4 coupling socket head screws to the
value provided in "ENGINEERING DATA" section
of this manual. After assembly, the gap between the
coupling halves should be equal.
For the 33 through 125SV sizes using a cartridge
seal, after coupling bolts have been properly torqued,
there are four set screws on the collar of the car-
tridge seal that require tightening before removing
the shim. The four hex head set screws require a 1/8"
allen wrench and are to be tightened hand-tight ap-
proximately 5 lbs.-ft. (7 N
Remove the motor assembly shim and retain for
future use.
Install the 2 coupling guard halves.

1. WATER CONNECTION

The water connections must be made by qualified
installation technicians in compliance with the regu-
lations in force.
In case of connection to the water system, the regula-
tions issued by the competent authorities (municipal,
public utility company) must be observed. Authori-
ties often require the installation of a backflow pre-
vention device, such as a disconnector, check valve
or disconnection tank.

servicing pump.
Electrical supply MUST match pump's name-
plate specifications. Incorrect voltage can cause
fire, damage motor and voids warranty.
Motors equipped with automatic thermal pro-
tectors open the motor's electrical circuit when
an overload exists. This can cause the pump to
start unexpectedly and without warning.
Use only stranded copper wire to motor and ground.
Wire size MUST limit the maximum voltage drop to
10% of the motor nameplate voltage, at the motor
terminals. Excessive voltage drop will affect perfor-
mance and void motor warranty. The ground wire
must be at least as large as the wires to the motor.
Wires should be color coded for ease of
maintenance.
Three phase motors require all leg protection with
properly sized magnetic starters and thermal over-
loads.
