The hazardous location
submersible pump family was
designed in ac cor dance with
requirements for haz ard ous
locations. These pumps,
connected prop er ly, will provide
years of trouble-free service. If
ser vic ing is required, the repair
should be done by a Hydromatic
approved ser vice center.

Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting non-operational for 3
months or longer and prior to
electrical start-up.
Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after
setting non-operational for 3
weeks or longer and prior to
electrical start-up.

All hazardous location
submersible pumps have two
factory installed mois ture
detectors (seal failure probes).
They are in a normally open series
cir cuit, in the seal chamber. Un der
normal operating conditions, the
circuit remains open. If the lower
seal leaks and moisture enters this
cham ber, the moisture would
settle to the bottom of the
chamber and will com plete the
circuit between the mois ture
detectors.
This circuit must be connected to
a sensing unit and signaling
device. This is supplied in a
Hydromatic built control panel.

All motors in this family have
heat sensors on or embedded
in the motor winding to detect
ex ces sive heat. This prevents
damage to the motor. If
sen sor trips due to excessive
winding tem per a ture, starter in
panel breaks power to the pump.
Once sensor re sets, the starter is
to be manually re set for UL;
automatic reset for FM for
continued operation of the pump.
This circuitry is supplied in a
Hydromatic control panel.
The sensors are set to trip at
120°C (248°F).
