Pump Installation and Service Manual

2
Thank you for purchasing your
Hydromatic®pump. To help
ensure years of trouble-free
operation, please read the
following manual carefully.
Pump
The explosion-proof submersible
pump family was designed in
accordance with requirements for
hazardous locations. These
pumps, connected properly, will
provide years of trouble-free
service. If servicing is required,
the repair should be done by a
Hydromatic approved service
center.
Application
These pumps are designed for on-
site residential sewage discharge
applications with a pH ranging
from 6 to 9, specific gravities from
0.9 to 1.1 viscosities ranging from
28 to 35 S.S.U., and temperatures
up to 140º F.
Receiving Pump
Pump should be checked on arrival
for possible concealed shipping
damage. Any damage should be
reported immediately to delivery
carrier. Claims for damage must
originate at the receiving end.
Claims for shipping damage
cannot be processed at the factory.
Codes
All local wiring codes must be
observed. Consult the local
inspector before installation to
avoid costly delays that can occur
due to rejection after job is
finished.
Pumps Not Operating or
in Storage
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.
Seal Failure Probes
All explosion-proof submersible
pumps have two factory-installed
moisture detectors (seal failure
probes). They are in a normally
open series circuit, in the seal
chamber.
Under normal operating
conditions, the circuit remains
open. If the lower seal leaks and
moisture enters this chamber, the
moisture would settle to the
bottom of the chamber and will
complete the circuit between the
moisture detectors.
This circuit must be connected to
a sensing unit and signaling
device. This is supplied in a
Hydromatic control panel.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic pumps.
Heat Sensors
All motors in this family have
heat sensors on or embedded in
the motor winding to detect
excessive heat. This prevents
damage to the motor. If the sensor
trips due to excessive winding
temperature, the starter in the
panel breaks power to the pump.
Once the sensor resets, the starter
is to be reset (automatic for F.M.)
for continued operation of the
pump. This circuitry is supplied in
a Hydromatic control panel. The
sensors are set to trip at 120º C.
NOTE: Failure to install such
circuitry would negate F.M.
approval and all warranties by
Hydromatic pumps.
General
Information
Power Cords
The power cord and heat sensor
seal failure cord are potted into
the connection box cap. The
cords must not be spliced.
NOTE: Each cable has a green
lead. This is the ground wire
and must be grounded properly
per N.E.C., and/or local codes.
During normal maintenance
procedures power cords should
be inspected for abnormal wear
and replaced accordingly.
Overload Heaters
If the Hydromatic electrical panel
is not used, starters with 3-leg
overload relay must be supplied
on 3-phase pumps. Each leg is to
have an identical heater sized in
accordance with the nameplate
amps on the motor housing. The
amp draw on these submersible
motors is slightly higher than
a corresponding horsepower
surface motor, so heaters must be
sized by the nameplate rating.
Single-phase pumps with
capacitor start have a run and a
start winding, each drawing a
different current. To adequately
protect these windings with the
appropriate heaters, consult the
factory.
NOTE: Red lead is always start
winding of pump using single
phase.
If pumps are installed in an
existing basin or concrete sump,
the piping can either be connected
permanently or rails and brackets
can be furnished for mounting to
walls of basin. In either case, be
sure the Hydromatic non-clog
ball check valve is used and that
the pumps are submerged in a
vertical position. The complete
factory built packaged system is
recommended for the most
satisfactory installation and

Making Electrical Connections
All electrical wiring must be in
accordance with local code, and
only qualified electricians should
make the installations. Complete
wiring diagrams are included for
use in making the installation.
All wires should be checked for
shorts to ground with an
ohmmeter or Megger after the
connections are made. This is
important, as one grounded wire
can cause considerable trouble.
IMPORTANT: If equipment
is not properly wired and
protected as recommended,
Hydromatic WARRANTY IS
VOID.
Heat Sensor and Seal Failure
Connection
If a Hydromatic control panel
is used, terminal blocks are
provided for heat sensor and seal
failure connections (see Panel
Schematic). If a control panel is
supplied by others, it must allow
heat sensor and seal failure
terminations.
Installing Sump Level Control
Float Controls
In either simplex, duplex or
triplex systems the lower or turn-
off control is to be set to maintain
a minimum level in the sump.
This level shall be no more than
3-1⁄2" from the top of the motor
housing down to the surface of the
sewage.
The second, or turn-on control, is
set above the lower turn-off
control. The exact distance
between the two floats must be a
compromise between a frequent
pumping cycle (10 starts per hour
maximum) to control septicity,
solids and a slower cycle for
energy economy. This distance
should be determined by the
engineer or consulting engineer,
Starting the Pump
To start the pump, perform the
following steps in order:
WARNING! Keep hands and
clothing away from cutters and
impeller!
1. If pump is 3 phase, the rotation
of the impeller must first be
checked. Lift pump from
sump, lay it down, and quickly
turn pump on and then off.
The impeller should turn
counterclockwise when
viewed from the suction. If
rotation is wrong, turn off main
breaker and interchange any
two line leads to motor to
correct rotation.
If the pump is piped-in
permanently and inlet cannot
be observed, rotation will have
to be checked by pump
operation described later.
If pump is single phase, no
rotation check is necessary.
2. Run water into sump until
motor is covered.
3. Open gate valve in discharge
line.
4. Turn pump on. If pump runs and
sump liquid does not pump
down, stop pump and close
discharge gate valve. Then lift
pump until sealing flange is open
to vent off trapped air. Lower
pump, open discharge valve, and
start the pump again.
If the pump is piped
in permanently, it may be
Unpacking Pump
Remove pump from carton.
Remove plywood base from
bottom of pumps.
Installing Pump in Sump
Before installing pump in sump,
lay it on its side and rotate
impeller. Impeller may be slightly
stuck due to factory test water so
it must be broken loose with a
small bar or screwdriver in edge
of vanes. The impeller should turn
freely. Do not connect the power
until after this test.
Clean all trash and sticks from
sump and connect pump to piping.
A check valve must be installed
on each pump.
Location
If pumps are installed in an
existing basin or concrete sump,
the piping can either be connected
permanently or rails and brackets
can be furnished for mounting to
walls of basin. In either case, be
sure the Hydromatic non-clog
ball check valve is used and that
the pumps are submerged in a
vertical position. The complete
factory built packaged system is
recommended for the most
satisfactory installation and
generally for the lowest cost
where expensive installation labor
is involved.

As the motors are oil filled, no
lubrication or other maintenance
is required.
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
intrinsically safe Hydromatic
panels as standard equipment.
Pump should be checked every
quarter for corrosion and wear.
Servicing Instructions:
IMPORTANT: Read all the
instructions before replacing
any parts.
WARNING: Before handling
these pumps and controls,
always disconnect the power
first.
Do not smoke or use sparkable
electrical devices or flames in a
septic (gaseous) or possible
septic sump.
Field Service on Hydromatic
Explosion-Proof Pumps:
If a Hydromatic explosion-proof
pump is used in a hazardous
location, or if the pump is still in
warranty, the pump must be
returned to the factory for service
or repaired in an authorized
Hydromatic service center. This
will ensure the integrity of the
hazardous location rating of the
pump and comply with our
warranty requirements. Pumps
out of warranty and not used in a
hazardous location can be field
serviced by any reputable
serviceman. When any field
servicing is performed on a pump,
the following instructions should
be followed carefully.
Disconnecting Pump Cords:
If a Hydromatic explosion-proof
pump is to be removed from its
location, 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
control panels) and cord assembly
taken with pump.
CAUTION: If cord openings
from sump to control panel are
open, gases from sump could
enter panel and an explosive
condition could exist. Seal
openings!
Pump cords may be disconnected
at pump by removing the cord and
cap assembly, unplugging sensor
wires, and removing wire nuts.
After removal from pump, reinstall
wire nuts in cord and cap assembly
and install protective cover.
(Required accessory item when
remote mounted control panel is
used PN #11159-000-1.)
Pump
Maintenance
CAUTION: Do not reconnect
power to a cord and cap assembly
while removed from pump.
Replacing Cords:
The power cord and heat
sensor/seal failure cord are potted
into the connection 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
available from factory.
1. Remove cord and cap assembly.
2. Disconnect wires taking note
of color/number coding.
3. Connect wires of new cord and
cap assembly in same manner
as old one was removed.
4. Reinstall cord and cap assembly
taking care not to pinch wires.
5. Check pump for proper
rotation before returning to
normal service.
Axial Cutter Adjustment:
To maintain the proper face
clearance between the axial cutter
(57) and the cutter ring (58),
follow this procedure.
1. Close gate valve at pump
discharge.
2. Turn off circuit breaker.
CAUTION: Never work on
pump unless power has been
turned off.
3. Remove pump from sump.
4. Referring to drawing, loosen
jam nuts (52) on set screws
(53) located on top of bearing
housing (8).
5. Loosen set screws (53).
6. Tighten hex head cap screws
(40) until axial cutter (57) just
drags on cutter ring (58) when
radial cutter (56) is turned by
hand.
necessary to break union at
pump discharge to clear air.
5. If pump is 3 phase, piped-in
permanently, and still does not
operate properly after venting,
rotation is wrong and can be
reversed by interchanging any
two line leads.
6. Level controls should be set in
accordance with “Installing
Sump Level Control Float
Controls” above.
CAUTION: Be sure ground
wire is connected to good
ground such as a water pipe.
This is important for safety.

7. Back off on hex screws (40) 1⁄8
turn.
8. Tighten set screws (53) to lift
axial cutter (57) for proper
face clearance.
9. Tighten jam nuts (52) on set
screws (53).
10.Again turn radial cutter (56) by
hand to determine if shaft has
any drag.
11.If there is still some drag,
repeat above steps and back off
hex screws (40) further.
IMPORTANT: Be sure that
both hex screws (40) are
tightened or loosened the same
amount and that the set screws
(53) are tight against the motor
housing (34). Also, remember
that the set screws (53) increase
the clearance while the hex screws
(40) decrease the clearance.
Replacing Grinder Parts:
If necessary to replace grinder
parts because of wear or to inspect
for clogging:
1. Close gate valve at pump
discharge.
2. Turn off circuit breaker.
CAUTION: Never work on
pump with power on. Be sure
ground wire from pump is
connected to a good ground
such as a water pipe.
3. Remove pump from sump.
4. Unscrew cap screws (19) and
remove cutter ring retainer (54).
5. Unscrew hex head cap screws
(15) and remove volute case (24).
6. Radial cutter (56) and axial
cutter (57) are now exposed. If
checking for clogging, these
parts can now be cleaned
without removing them from
the shaft.
7. If necessary to replace cutters,
remove cap screws (21),
washer (20), and radial cutter
(56) and impeller (18) from
shaft while tapping with a
plastic hammer to loosen.
Disassemble radial cutter (56)
and axial cutter (57) from the
impeller (18) by removing
socket head cap screws (25).
8. Clean all parts thoroughly
before proceeding with assembly.
Replace impeller (18), axial
cutter (57), and radial cutter
(56) and secure together with
socket head cap screws (25).
Make sure impeller key (55) is
in place between shaft and
impeller (18).
9. Loosen hex head screws (40)
1/2 turn. Replace cutter ring
(58) and cutter ring retainer
(54). Now repeat steps 4
through 11 under Axial Cutter
Adjustment. It may be
necessary to loosen hex head
cap screws (15) in pump case
(24) and tap with a hammer to
get proper clearance on O.D.
of radial cutter (56).
10.Plug pump into power and
operate for a few seconds only
to ensure parts are not rubbing.
Replacing Seals:
1. Remove pipe plug (12) from
motor and seal chamber and
drain out all oil. The lower
pipe plug drains the seal
motor housing. Check for
water in the oil drained from
motor chamber. If there is
some water in this oil, the
pump must be completely
dismantled and the stator
dried out or replaced if the
resistance to ground is less

than 500,000 ohms after
drying. A hypot check of 1,500
volts for 230 volt motors and
2,000 volts for 460 volt motors
should be performed.
2. Remove cutters, impeller and
pump parts as described under
“Replacing Grinder Parts”.
3. Remove socket head cap screw
(25) in seal plate (17) and
screw two of the screws into
the tapped back-off holes to
force seal plate (17) from seal
housing (27). Pulling this plate
(17) off will also force seal
(23) from shaft. Remove lower
seal (23) from seal plate (17).
4. Remove snap ring (26) and
pull upper seal (28) from shaft.
It may be necessary to use
packing hooks to remove seal.
Use a screwdriver to break the
upper stationary ceramic seal
ring so that it can be removed
easily.
CAUTION: Do not use any old
seal parts. Replace all parts
with new pieces. Mixing old and
new parts will cause immediate
seal failure.
5. When cleaning all parts before
replacement, check to be sure
sleeve bearing or shaft is not
worn. Be sure all O-rings are in
excellent condition without
cuts or nicks, and replace them
if not in excellent condition.
Use O-ring lube to prevent
cutting at assembly.
6. After upper seal is replaced we
recommend an air test be made
by inserting 5 lb. of air pressure
into the motor housing and
allow ample time for air to
escape. If pressure remains
Pump
Maintenance
steady for five minutes
continue by replacing lower
seal plate, lower shaft seal and
impeller. Repeat the air test in
the seal chamber. If this test
is satisfactory, complete the
assembly and cutter adjustment
as described earlier. Next the
pump must be filled with oil.
Start by filling the seal
chamber. Do not fill it
completely. Allow about 1/2"
air space for expansion. Next
fill the motor housing just
above the motor winding.
7. Use only Hydromatic
submersible oil in motor
chamber and seal chamber. In
an emergency, a high grade
transformer oil can be used
in the motor chamber and #20
non-detergent automobile oil
can be used in the seal chamber.
Replacing Motor Stator:
1. If necessary to replace stator,
completely dismantle pump as
described above.
2. Drain all oil from upper housing.
Remove drain plug (12) in
bottom of bearing housing, and
remove bearing housing (8)
and rotor and shaft assembly
(33). When housing and rotor
are removed, motor leads can
be disconnected through
the bearing cap bore. The
leads are connected with
connectors and must be cut.
DO NOT TAPE LEADS
WHEN REPLACING STATOR
AS OIL WILL DETERIORATE
THE TAPE AND CAUSE
MOTOR FAILURE. USE
ONLY INSULATED BUTT
CONNECTORS.
3. If cord leads are burned, it will
be necessary to replace power
cord and cord group assembly
(1). If any wires in the
connection box (41) are
burned, it will be necessary to
replace the connection box
assembly. Connect wires per
connection diagram.

4. Remove motor housing bolts
(29) and lift off housing (34).
Use care in lifting as the seal
failure connection wire must
be disconnected before housing
is completely removed.
5. Remove stator screws (31) and
set housing (34) on hardwood
blocks. Bump housing (34)
up and down on hardwood
block to loosen stator which
should drop out. On some 3
and 5 HP units, a stator spacer
ring (36) will also drop out.
This should be reinstalled with
the new stator.
6. Thoroughly clean housing (34)
and other parts and install
new stator.
7. Connect leads through housing
bore and tuck leads back
behind the stator windings
to prevent rubbing on rotor.
USE ONLY INSULATED
BUTT CONNECTORS TO
CONNECT WIRES.
8. If the ball bearing (37) is
rusted or feels rough when
turned, it should be replaced.
Remove hex head cap screw
(38) and washer (39) and press
the bearing off the shaft. Install
the new bearing by pressing on
inner face only. PRESSING
ON THE OUTER FACE
WILL RUIN THE BEARING.
9. In reassembly, replace any
O-rings that are defective. Use
Parker O-Ring Lube on all
O-rings for easy assembly and
to prevent cutting.
10.Completely reassemble, making
sure seal failure wires are
connected.
11.Make a high voltage ground
test on each wire. The only
Pump
Maintenance
wires that should show ground
are the two green leads.
12.Air test the motor housing and
the seal housing by inserting
5 lb. of air pressure and allow
ample time for air to escape. If
pressure remains steady for
five minutes, you are ready to
fill the pump with oil.
13.Fill seal chamber with oil by
laying pump on side with oil
fill hole upright. Do not
completely fill; leave oil about
1⁄2" below plug hold. Use only
Hydromatic submersible oil.
Replace plug with Permatex on
threads.
14.Refill motor chamber with
oil through connection box
opening. Use high grade, non-
synthetic transformer oil or
Hydromatic special submersible
oil. Fill housing until oil covers
top of windings. Leave air
space for expansion.
15.Always run pump for a few
seconds after assembly work to
be sure all parts run smoothly
and are correctly adjusted
before replacing in sump.
Check again for correct
rotation. Pump should rotate
counterclockwise when viewed
from the suction.
NOTE: When applying power,
be sure the pump is restrained
from turning by holding the
pump at the motor housing or
by clamping it in a holding
fixture.
CAUTION: Always keep hands
away from the pump cutter
area after the circuit breaker
is reconnected.

LIMITED PRODUCT WARRANTY
HYDROMATIC®warrants that its products are free from defects in material and workmanship for a period of
twelve (12) months from the date of purchase or eighteen (18) months from the date of manufacture, whichever
occurs first.
During the warranty period and subject to the conditions hereinafter set forth, HYDROMATIC, will repair or
replace to the original user or consumer parts which prove defective due to defective materials or workmanship
of HYDROMATIC. Contact the nearest authorized HYDROMATIC distributor, HYDROMATIC authorized
service center or HYDROMATIC for warranty service. At all times, HYDROMATIC shall have and possess
the sole right and option to determine whether to repair or replace defective equipment, parts or components.
Start up reports and electrical system schematics may be required to support warranty claims. Warranty is
effective only if HYDROMATIC supplied or authorized control panels are used, where applicable. All dual
seal pumps must have seal failure and heat sensors attached, functional and monitored for the warranty to be
in effect. If a seal failure should occur, HYDROMATIC will only cover the lower seal and labor thereof. If the
heat sensor and seal fail sensor is not attached and functional, the warranty is void.
LABOR, ETC. COSTS: HYDROMATIC shall in NO EVENT be responsible or liable for the cost of field labor,
removal and/or reinstallation charges of any HYDROMATIC product, part or component thereof, or the
expense of freight.
THIS WARRANTY WILL NOT APPLY: (a) to defects or malfunctions resulting from failure to properly install,
operate or maintain the unit in accordance with printed instructions provided; (b) to failures resulting from
abuse, accident or negligence; (c) to normal maintenance services and the parts used in connection with such
service; (d) to units which are not installed in accordance with applicable local codes, ordinances and good
trade practices; or (e) if the unit is moved from its original installation location; (f) unit is used for purposes
other than for what it was designed and manufactured; (g) to any unit which has been repaired or altered by
anyone other than HYDROMATIC, a HYDROMATIC distributor or a HYDROMATIC authorized service
center and (h) to any unit which has been repaired using non factory specified parts/OEM parts.
RETURN OR REPLACED COMPONENTS: any item to be replaced under this Warranty must be returned
to HYDROMATIC in Ashland, Ohio, or such other place as HYDROMATIC may designate, freight prepaid.
PRODUCT IMPROVEMENTS: HYDROMATIC reserves the right to change or improve its products or any
portions thereof without being obligated to provide such a change or improvement for units sold and/or
shipped prior to such a change or improvement.
WARRANTY EXCLUSIONS: HYDROMATIC MAKES NO EXPRESS OR IMPLIED WARRANTIES WHICH
EXTEND BEYOND THE DESCRIPTION ON THE FACE HEREOF. HYDROMATIC SPECIFICALLY DISCLAIMS
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY PARTICULAR PURPOSE.
Some states do not permit some or all of the above warranty limitations and, therefore, such limitations may
not apply to you. No warranties or representations at any time made by any representatives of
HYDROMATIC shall vary or expand the provision hereof.
LIABILITY LIMITATION: IN NO EVENT SHALL HYDROMATIC BE LIABLE OR RESPONSIBLE FOR
CONSEQUENTIAL, INCIDENTAL OR SPECIAL DAMAGES RESULTING FROM OR RELATED IN ANY MANNER
TO ANY HYDROMATIC PRODUCT OR PARTS THEREOF. PERSONAL INJURY AND/OR PROPERTY DAMAGE
MAY RESULT FROM IMPROPER INSTALLATION. HYDROMATIC DISCLAIMS ALL LIABILITY, INCLUDING
LIABILITY UNDER THIS WARRANTY, FOR IMPROPER INSTALLATION — HYDROMATIC RECOMMENDS
INSTALLATION BY PROFESSIONALS.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you.
This Warranty gives you specific legal rights and you may also have other rights which vary from state to state.
In the absence of suitable proof of this purchase date, the effective date of this warranty will be based upon
the date of manufacture.
