Field Service on Hydromatic
Hazardous Location Pumps:
If a Hydromatic hazardous
location pump is used in a
hazardous location the pump must
be returned to the factory for
service. This will ensure the
integrity of the hazardous location
rating of the pump and com
ply
with our warranty re
quire
ments.
Pumps out of warranty and not
used in a hazardous location can
be field serviced by any reputable
serviceman. When any field
servicing is per formed on a pump,
the fol low ing in struc tions should
be followed care ful ly.
Disconnecting Pump Cords:
If a Hydromatic hazardous
location pump is to be removed
from its lo ca tion, one of two ways
may be used to disconnect the
pump cords from the rest of the
system.
Pump cords may be disconnected
at control panel (on sump mounted
con trol panels) and cord as sem bly
taken with pump.
CAUTION: If cord openings
from sump to con trol panel are
open, gas
es from sump could
enter panel and an explosive
condition could ex ist.
Pump cords may be disconnected
at pump by removing the cord and
cap assembly, unplugging sensor
wires, and re mov ing wire nuts.
After removal from pump,
reinstall wire nuts in cord and cap
assembly and install protective
cover.
CAUTION: Do not reconnect
pow
er to a cord and cap
assembly while removing from
pump.
Replacing Cords:
The power cord and heat
sensor - seal failure cord is potted
into the con
nec
tion box cap,
forming
the cord and cap
assembly.
If cords require replacement due
to damage or cords being too
short, cord and cap assembly
must be replaced as a complete
assembly avail able from factory.
1.
Remove cord and cap
assembly
from
con nec tion
box.
2. Disconnect wires taking note
of color/num ber coding.
3. Connect wires of new cord
and cap as sem bly in the same
manner as the old one was
removed.
4.
Check for moisture and
dryout.
5. Reinstall cord and cap assembly
on con nec tion box taking care
not to pinch wires.
6.
Check pump for proper
rotation before re
turn
ing to
normal service.
Replacing Stator:
If motor winding is burned or
shorted, it can be rewound or
replaced with new factory wound
sta tor. Refer to sectional drawing
of pump and motor, and use the
following steps to remove and
replace stator.
As the motors are oil filled, no
lubrication or other main
te
nance
is re quired.
If the heat sensor and seal failure
are hooked up properly, no
attention is necessary as long as
the seal failure indicator light
doesn’t come on. To ensure
continuity of the seal sensor leads,
a test light is provided on
in trin si cal ly
safe
Hydromatic
panels as standard equipment.
Pump should be checked every
quar ter for cor ro sion and wear.
Servicing Instructions:
IMPORTANT: Read all
directions before replacing
any parts.
