Thank you for purchasing your
Hydromatic®pump. To help
ensure years of trouble-free
operation, please read the
following manual carefully.
Before Operation:
Read the following instructions
carefully. Reasonable care and
safe methods should be practiced.
Check local codes and
requirements before installation.
Attention:
This manual contains important
information for the safe use of
this product. Read this manual
completely before using this
product and refer to it often for
continued safe product use.
DO NOT THROW AWAY OR
LOSE THIS MANUAL. Keep it
in a safe place so that you may
refer to it often.
Unpacking Pump:
Remove pump from carton. When
unpacking unit, check for
concealed damage. Claims for
damage must be made at the
receiving end through the delivery
carrier. Damage cannot be
processed from the factory.
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.
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 140
degrees Fahrenheit.
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 nonoperational 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
General
Information
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 120
degrees Celsius.
NOTE: Failure to install such
circuitry would negate F.M.
approval and all warranties by
Hydromatic pumps.
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.
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 HYROMATIC nonclog
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.
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 Meggar 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 31⁄2" 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,
depending on the conditions of the
application.
For installation of Hydromatic
supplied level controls refer to
your system’s installation and
service manual.
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.
Starting the Pump:
To start the pump, perform the
following steps in order:
WARNING! Keep hands and
clothing away from cutters
and impeller!
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.

1. If 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 pump is piped in permanently,
it may be 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.
Pump
Operations
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
3 months for corrosion and wear.
Servicing Instructions:
IMPORTANT: Read all
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 shop. 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.)
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.

Pump
Maintenance
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 the same
manner as the 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.
Cutter Adjustment:
There is no cutter adjustment
necessary as all adjustments have
been factory set.
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 (18) and
remove cutter ring retainer (41).
5. Unscrew hex head cap screws
(14) and remove volute case (23).
6. Radial cutter (43) and axial
cutter (44) 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 serrated head cap screw
(20), washer (19), radial cutter
(43) and impeller (17) from
shaft while tapping with a
plastic hammer to loosen.
Disassemble radial cutter (43)
and axial cutter (44) from the
impeller (17) by removing
socket head cap screw (21).
8. Clean all parts thoroughly
before proceeding with assembly.
Replace impeller (17), axial
cutter (44), and radial cutter
(43) and secure together
with socket head cap screws
(21). Make sure impeller key
(42) is in place between
shaft and impeller (17).
Replace volute case (23),
replace grinder ring (41).
9. Plug pump into power and
operate for a few seconds only
to ensure parts are not rubbing.
Replacing Seals:
1. Remove pipe plug (11) from
motor and seal chamber and
drain out all oil. The lower
pipe plug drains the seal
housing and the upper pipe
plug drains the 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
(29) in seal plate (16) and
screw two of the screws into
the tapped back off holes to
force seal plate (16) from seal

7
housing (26). Pulling the seal
plate (16) off will also force
the lower seal (22) from shaft.
Remove lower seal (22) from
seal plate (16).
4. Remove snap ring (25) and
pull upper seal (27) 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
bearings 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 (27) 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 steady for five minutes
continue by replacing the seal
plate (16), lower shaft seal (22)
and impeller (17). Repeat the
air test in the seal chamber.
Next the pump must be filled
with oil. Start by filling the seal
chamber. Do not fill completely.
Allow about 1⁄2inch 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
(30), completely dismantle
pump as described above.
2. Drain all oil from upper
housing. Remove drain plug
(11) in bottom of bearing
housing, and remove connection
box assembly (34) by removing
capscrews (37). Motor leads
can be disconnected. 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 (34) are
burned, it will be necessary to
replace the connection box
assembly. Connect wires per
connection diagram.
4. Remove motor housing bolts
(28) and lift off motor housing
(32). Use care in lifting as the
seal failure connection wire
must be disconnected before
housing is completely removed.
5. Remove stator screws (29) and
set motor housing (32) on
hardwood blocks. Bump motor
housing (32) up and down on
hardwood block to loosen
stator which should drop out.
This should be reinstalled with
the new stator.
6. Thoroughly clean motor housing
(32) 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 upper ball bearing (33)
is rusted or feels rough
when turned, it should be
replaced. 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 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,
nonsynthetic transformer oil
or Hydromatic special
submersible oil. Fill housing
until oil covers top of windings.
Leave air space for expansion.

Pump
Maintenance
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.

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.
