General
Information
Pump
Warning
7. For proper automatic operation,
make sure the pump power
cord is plugged into the
piggyback receptacle on the
diaphragm switch cord.
Do not cut, crimp, or bend
switch power cord. The vent
tube needs to “breathe” for
proper operation of switch.
This may cause pump failure
and void warranty.
8. Connect to separate electrical
circuit taken directly from
main switch.
9. Use steel or plastic pipe for all
connecting lines between
pump and sewer outlet.
Note: Some city regulations
do not allow installing a
pump with plastic pipe. Check
local regulations.
10.In applications where the
pump may sit idle for months
at a time, it is recommended
that the pump(s) be cycled
every month to ensure the
pumping system is working
properly when needed.
11.Hydromatic check valve
should be installed in
discharge pipe.
12.The Hydromatic Q Alert is an
audible alarm system
for high water conditions. It
should be installed in every
pump pit for greater protection.
Note: Q Alert is for indoor
use only. Other Q Alarm and
control panels are available
for outdoor use. Contact your
Hydromatic distributor for
applications.
These important instructions
must be followed for satisfactory
performance of your pump:
1. Provide proper sump (minimum
sump diameter of 18").
2. Do not set pump directly on
the bottom of sump pit if it is
not solid. Raise the pump by
using bricks or concrete blocks
underneath it.
3. Make sure sump is free of
string, cloth, nails, gravel, etc.,
before installing pump.
4. Risk of electrical shock–connect
only to a properly grounded,
grounding-type receptacle.
5. Do not remove ground pin
from electrical plug.
6. Do not use an extension cord.

Servicing
Read the following instructions
carefully before replacing any
parts. Reasonable care and safe
methods should be practiced.
Check local codes and
requirements before installation.
Only a competent electrician
should make the installations.
The following steps should be
performed by an authorized
service center.
Important: Read all directions
before replacing any parts.
Remove pump and switch from
power source before servicing.
1. Replacing diaphragm switch.
From switch housing (9)
remove screw (8) from housing.
Replace with new switch.
Insert screw (8) into housing
(9) and tighten. Plug pump
into switch and switch into
correct power source.
2. Replacing wide angle switch.
From motor housing (21)
remove switch tethering screw
(29). Replace with new switch
(27) with new switch tethering
screw (29). Plug pump into
switch and switch into correct
power source.
Note: To be sure wires are
not burned or broken in cord,
use ohmmeter for check. Set
ohmmeter scale pointer to R 2 1
scale and attach one meter lead
to white cord wire and one
meter lead to black cord lead.
Place screwdriver blade across
blade terminals of plug (1). If
cord is functional, the meter will
go to zero (0). If open (∞), cord
must be replaced.

4
Remove bolts (6) to separate
volute case (14) from motor
housing. Remove O-ring (18)
and seal plate (13) from motor
housing. Remove bolts to
separate motor-stator (20)
from rotor. If stator is visibly
burned, it must be replaced. If
stator is not burned but the oil
shows signs of water stator can
be checked with the ohmmeter
to see if it can be used.
6. Ground check. Set ohmmeter
scale pointer to R 2 100K scale
and check meter by putting
both meter leads together
and adjusting the needle knob
until meter reads zero. If meter
cannot be adjusted to zero it
will indicate that batteries in
meter must be replaced.
Note: Always reset meter to zero
(0) when going to a new scale
before making any checks on
motor. Connect one meter lead
to one blade terminal of stator
and touch other meter lead to
motor stator shell. If needle
reads below 500,000 ohms
stator must be dried out before
retesting. To dry out, place in
220 degree oven four hours.
Recheck after motor cools.
If motor is thoroughly dry,
needle of ohmmeter will not
move on the ground check.
This indicates a reading of
50 megohm or higher. One
megohm is one million ohms.
When making the ground
check, if the needle goes to zero
the motor in all probability has
a wire touching the stator shell
at some point and the stator will
have to be replaced.
Note: If motor shows a
satisfactory ground check then
the winding resistance must
be checked.
7. Winding resistance test. Use
ohmmeter with scale pointer
set on R 2 1 scale. On this
scale, meter reads directly on
ohms. Recheck to zero (0)
before making a reading on
the winding.
Note: If water is found in motor,
seal should be replaced.
8. Replacing seal. Remove (3
phase pumps only) the
impeller screw (31) and
impeller washer (30). Hold
rotor and unscrew impeller
(12). Bump on end of shaft
with plastic or rubber hammer.
This will push the rotating seal
(11) from shaft and also push
lower bearing from seal plate.
Clean seal plate (13) and motor
housing (21) thoroughly. All
sand and dirt must be removed.
Remove stationary ceramic seat
of seal (10) from seal plate.
Push new ceramic seat into
seal plate. Use Parker O-ring
Lube on rubber ring. Replace
rotor in seal plate (13). Use
care in putting shaft through
ceramic seat to be sure it is not
chipped. Inspect seal after shaft
is in place. If seal has been
chipped it must be replaced. Do
not replace rotating part of seal
until the balance of the pump
is assembled.
9. Bearings. When the pump
rotor has been removed, check
bearings before replacing. If
bearings are rusted or rough
when turned, they should be
replaced. Pull bearings with a
bearing puller. If puller cannot
be replaced over lower bearing,
remove the outer face by
cracking in a vice. After outer
face is cracked, it can be
removed and the balls can be
removed. This will allow inner
face to be pulled. When
Pump
Servicing
3. Checking motor operation.
Plug power cord in power
receptacle to check motor
operation. Motor should start
and run smoothly. If motor
does not start, pump must be
dismantled and motor checked.
Be certain to unplug cord before
disconnecting any wires.
4. Checking switch housing for
leaks. After switch is replaced
and ready for operation, switch
housing must be checked for
air leaks. Use air hose and
blow air into switch housing
through nylon vent tube. Do
not put air nozzle directly
against tube but blow air with
nozzle about 1⁄8inch from tube
end. Blow into tube then
remove nozzle and hold finger
over end of nylon tube. Place
plug near your cheek, then
release finger to be sure air is
in housing. Hold tube and
place complete pump unit
under water. Recharge housing
with air if necessary. An initial
surge of air bubbles will
appear, then none.
Note: If motor does not run
when tested as described above,
the stator must be removed
from the housing and checked.
5. Checking motor stator.
Remove plug (3) from top
of housing, and pour oil in
container, preferably glass, so
that oil can be observed. If oil
is clear it will indicate motor is
not burned and there has been
no water leaking into the
motor. If oil is cloudy or black,
it will indicate water in the
motor or a burned stator.

5
replacing bearings push only
on inner face. If a press is
not available, bearings can be
tapped on, using a sleeve that
bears only on the inner face.
Note: Never pound on the outer
face of the bearing. This will
cause bearing damage.
10.Push the new rotor shaft and
ball bearing assembly into the
seal plate. (Note that the
replacement rotor must be of
the same manufacture as the
existing stator, or vice versa.)
Reassemble the motor (20)
to the seal plate (13) with the
four long cap screws. Be sure
to tighten down the bolts
evenly and firmly to prevent
cocking of the stator. An
uneven assembly can cause the
rotor to rub the motor causing
the motor to short.
11.Press the new ceramic seal
(11) in place with the rubber
ring facing the impeller. This
should have a thin oil
(dielectric, same as in motor
housing) coating.
Note: Ceramic must be kept
clean. Any dirt will cause
seal failure.
12.Start the impeller (12) on the
shaft one to two turns; then,
add a drop of Loctite #277 to
the impeller threads and screw
the impeller hand tight. The
impeller will force the ceramic
seal into position. The shaft
should be free of dirt, grease,
etc., or the Loctite will not
hold as designed. On three
phase models only, replace
impeller washer (30) and
impeller screw (31) to the
shaft.
Note: Loctite overrun onto the
seal or bearing will result in
shaft seizure.
13.Remove the old seal ring (18)
and stretch on new ring with
O-ring lube.
Do not roll the ring onto seal
plate or water leakage into the
motor housing will result.
14.Fasten the ground wire (22)
inside the motor housing and
tuck wires up into the housing
to prevent rubbing on the rotor;
then assemble housing (21) to
volute (14) with bolts (6).
15.Check for seal leaks by
pressurizing the pump to 7 to 9
pounds of air pressure. Air
bubbles should appear at first
then stop. If air bubbles
continue, recheck seals.
Hydromatic pumps have a
small air vent hole in the
impeller cavity to let out
trapped air. If this hole
becomes plugged, pump may
air lock. To break the air
lock, use a small screwdriver
to clear hole in the impeller
cavity.
As a secondary precaution in
installations of this type, 1 ⁄ 16"
hole should be drilled in the
discharge pipe below the check
valve. The check valve should
be 12 to 18 inches above pump
discharge. Do not put check
valve directly into pump
discharge opening.
NOTE: In sumps where the
pump is operating daily, air
locking rarely occurs.
16.Oil fill. After air test is
satisfactory, remove unit from
water and wipe or blow off any
excess water.
Do not put oil in motor
with any water present in
motor cavity.
Fill oil to 1 ⁄ 8" over windings
in motor housing through
opening (11). Use oil fill tube
that will go into holes so that
air can escape. Replace plug
(3) and pump is ready for
operation. Use only high grade
transformer oil.
17.Manual pumps. All general
instructions for automatic
pumps apply to manual pumps
except the level switch is not
used and the power cord does
not have a vent tube.
Manual models have the
plug (3) in switch cap for
installing a fitting to air test
the pump for leaks. Replace
all plugs with Permatex on
threads. The switch housing
seat is tapped and plugged
with pipe plug.
