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.
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.
Pumps in Storage or Not
Operating:
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.
50 Cycle or WYE Delta:
For information and parts list for
50 cycle or wye delta start pumps
refer to Addendum S4HRC-701.
Seal Failure:
An electrode is installed in the
seal chamber so if any water
enters the chamber through the
first seal the electrode will be
energized and a signal will be
transmitted to the sensing unit at
ground surface causing an alarm
function to energize.
In operation the seal failure unit
indicates only that there is some
water in the seal chamber. The
pump will continue to operate
without damage, but the seal
should be checked immediately
after failure is indicated.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic.
Pump:
The S4HRC submersible pumps
are supplied for 1 and 3 phase and
for 200, 230, 460 or 575 volts.
Pump is supplied with 30 feet
of power cord and/or 30 feet of
auxiliary control cord. Longer
cable lengths can be furnished but
must be specified at time of order.
Power cable is 4 wire with the
green wire for ground. Be sure
General
Information
green wire is connected to a good
ground such as water pipe or
ground stake. The auxiliary cable
for seal failure and heat sensors is
also 4 wire color coded.
Heat Sensors:
All motors have heat sensor units
embedded in the motor winding to
detect excessive heat. The heat
sensors are set to trip at 105°C so
will not operate if dangerous heat
occurs. The sensors automatically
reset when motor cools to safe
temperature.
The sensors are connected in
series with the motor starter coil
so that the starter is tripped if heat
sensor opens. The motor starter is
equipped with overload heaters so
all normal overloads are protected
by the starter.
NOTE: Failure to install such a
device negates all warranties by
Hydromatic pumps.
IMPORTANT: If Hydromatic
electrical starting equipment is
not supplied, the heat sensor
circuit must be connected in
series with the starter coil or
warranty on motor is void.
Connection diagram is included
in this manual.
Sump Level Control:
Sump level is controlled by
Hydromatic 3900 mercury switch
controls. The 3900 control is a
mercury tube switch sealed
in a solid polyurethane float.
The float is held in position in the
sump by a weight attached to
the power cord above the float.
The cord supports the float and
is adjusted for height from
the surface.
Typical duplex systems use three
controls: one set at turn-off, one

3
Alarm Controls:
The alarm level is usually set
above the override level so
the alarm will signal only if the
override level is exceeded.
However, some engineers prefer
to have the alarm level set below
the override level as it is possible
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reaching the alarm level. This is
particularly true in cases of low
inflow capacity.
Electrical Control Panel:
It is recommended that the
Hydromatic control panel be used
with all pumps as proper starter
heaters and connections for heat
sensor wires are furnished.
IMPORTANT: If Hydromatic
electrical controls are not used
and the motor fails because of
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate operation on each
successive cycle.
Two pumps operate together only
if sump level rises to the third or
override control. The override
control also brings on the second
pump in case of failure of the first
pump. Extra floats with
appropriate controls can be
supplied for alarm functions.
Triplex systems use four controls:
one set at turn-off, one set at
turn-on for one pump, one set at
turn-on for two pumps, and
one set at turn-on for three
pumps. Pumps alternate each
successive cycle.
Three pumps operate together
only if sump level rises to the
fourth control (second override).
This control also brings on the
third pump in case of failure
of either or both of the first
two pumps.
improper components or if the
heat sensors are not properly
connected the motor guarantee
is void.
Hydromatic electrical equipment
is installed in a weather-proof
NEMA 3R enclosure. The
electrical equipment includes a
maincircuit breaker for each
pump, a magnetic starter with
overload protection for each
pump, an H-O-A switch and run
light for each pump, an electric
alternator and a transformer to
provide appropriate control
for control circuit and alarms.
Overload Heaters:
If the Hydromatic electrical panel
is not used, starters with 3 leg
overload protection must be
supplied. On 3 phase pumps the
heaters must be sized in
accordance with the nameplate

always be submerged during the
pumping cycle. The second
or turn-on control is set about
24 inches above the lower
turn-off control.
More distance between turn-on
and turn-off controls can be used,
but sewage may become septic
and excessive solids may collect
for the pump to handle. A
frequent pumping cycle is
recommended for best operation.
If an alarm system is used, this
control is usually set about 6
inches above the override control.
Some engineers as described
previously prefer to have the
alarm control set below the
override control.
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.
IMPORTANT: If other than
Hydromatic starters are used,
be sure the heat sensor wires are
connected in series with the
starter coil circuit. Typical
wiring diagrams are included.
Hydr-O-Rail:
If the pump or pumps are to be
used with Hydr-O-Rail system,
the pumps will be equipped with
guide brackets and hydraulic
sealing flange.
check valve the line pressure can
be cut off. Single pump systems
are sometimes installed without a
check valve where it is desirable
to self-drain the discharge line to
prevent freezing. This can be
done only with short discharge
lines, otherwise water will return
to the sump and cause short
cycling of the pump.
NEMA 4 Junction Box
(Optional):
If electrical control panel is to be
set remote from the pump sump, a
NEMA 4 junction box should be
used to make power and control
connections. The Hydromatic
NEMA 4 junction box is provid-
ed with compression connectors
for sealing all wires. No sealing
compound is needed to make
connections waterproof.
Wiring diagrams are provided
with the panel for making
connections. An extra set of
diagrams is included so that one
set can be used in the sump when
making connections. The size
wire to use from panel to sump
depends on motor size and
distance in feet.
Be sure each wire is checked out
so that a wrong connection will
not be made.
Installing 3900 Mercury
Switch Controls:
The controls are supported by a
mounting bracket that is attached
to sump wall or cover or to the
NEMA 4 junction box.
Cord snubbers are used to hold
the cord in place. Control level
can be changed at any time
by loosening the snubber and
readjusting cord length.
In either simplex or duplex
system the lower or turn-off
control is set just above the top of
volute so that the volute will

Instructions
Installing Pump in Sump:
Before installing pump in sump
lay it on side and turn impeller
manually. Impeller may be
slightly stuck due to factory test
water so it must be broken loose
with small bar or screwdriver in
edge of vanes. The impeller
should turn freely.
Clean all trash and sticks from
sump and connect pump to piping.
A check valve must be installed
on each pump. A gate or plug
valve in each pump discharge line
is also recommended. This valve
should be installed on the
discharge side of the check valve
so if necessary to service the

Making Electrical Conections:
All electrical wiring must be in
accordance with local code, and
only competent electricians
should make the installations. A
set of prints is included for use in
making the installation. All wires
should be checked for grounds
with an ohmmeter or Megger
after the connections are made.
This is important, as one
grounded wire can cause
considerable trouble. See Fig. 1.

Heat Sensors and Seal Failure
Connections:
Be sure that heat sensor wires are
connected in series with
the starter coil. Connections are
provided on the terminal strip; see
wiring diagram.
If seal failure unit is used,
connect as shown with seal
failure system. If seal failure unit
is not used, the two seal failure
wires are left open. Do not
connect power to these lines at
any time. See Figs. 2 and 3.

Pump
Operation
As the motors are oil filled no
lubrication or other maintenance
is required.
If a seal failure unit is used, no
attention is necessary as long
as the seal shows satisfactory
operation.
If seal failure is not used, the
pump should be lifted once every
two years and the oil be drained
from the seal chamber to check
for water.
If the pump is used on a
Hydr-O-Rail system, it should be
lifted once every six months and
checked for corrosion and wear.
Generally these pumps give
very reliable service and can be
expected to operate for years
on normal sewage pumping
without failure.
Lightning:
In some areas where considerable
lightning occurs, it is
recommended that a lightning
arrestor be installed at the
control panel.
Complete data on lightning
arrestors and cost is available
from the factory. Lightning
arrestors are good insurance
against damage to an expensive
motor.
Servicing Instructions:
IMPORTANT: Read all the
instructions before replacing
any parts.
Starting System:
1. Turn H-O-A switch to Off
position, then turn on main
circuit breakers.
2. Open all discharge valves and
allow water to rise in sump.
3. Turn H-O-A switch to Hand
position on one pump and
notice operation. If pump is
noisy and vibrates, rotation is
wrong. To change rotation on
3ø motors, interchange any
two line leads to motor. DO
NOT INTERCHANGE MAIN
INCOMING LINES. If duplex
system, check second pump in
the same manner.
4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until one
pump starts. Allow pump to
operate until level drops to
turn-off point.
5. Allow sump level to rise to
start other pump. Notice run
lights on panel; pumps should
alternate on each successive
cycle of operation.
6. Turn both H-O-A switches
to OFF position and allow
sump to fill to the override
control level.
7. Turn both switches to Auto
position and both pumps should
start and operate together until
level drops to turn-off point.
8. Repeat this operation cycle
several times before leaving
the job.
9. Check voltage when pumps
are operating and check the
amp draw of each pump.
Check amps on each wire
as sometimes a high leg
will exist. One leg can be
somewhat higher, 5 to 10%,
without causing trouble. For
excessive amp draw on one
leg, the power company should
be consulted.
Pump
Maintenance
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 Motor:
All submersible motors can
be serviced (out of warranty) in
the field by any reliable motor
service shop. Any pump (in
warranty) must be returned to the
factory for service or repaired in
an authorized Hydromatic service
center. Charges will not be
allowed if (in warranty) pump is
taken to a motor repair shop that is
not an authorized Hydromatic
service center.
When field service is performed
on a pump, these instructions
should be carefully followed.
Replacing Stator:
If motor winding is burned or
shortened, it can be rewound or
replaced with new factory wound
stator. Refer to sectional drawing
of pump and motor and use the
following steps to remove and
replace stator.
1. If stator only is damaged it
may not be necessary to
completely dismantle pump as
stator and housing can be lifted
from pump without disturbing
seals or bearings.
2. Drain all oil from upper
housing, remove from upper
housing, remove drain plug in
bottom of stator housing and
remove plug in top of housing
to allow air to enter.
3. After chamber is drained,
remove hold-down bolts
and lift off. Use care in
lifting as the seal failure

7
connecting wire must be
disconnected before housing
is completely removed. See
sectional drawing.
4. Set assembly on bench and
remove connection box. When
box is lifted off, connection
wires to motor will be exposed.
These wires will probably be
burned, but each wire is tagged
with a metal marker giving
wire number. Cut the wires.
If the leads to the connection
box are burned, a complete
new connection box with new
wire must be used. The wires
are potted in with sealing
compound and a new unit must
be obtained from the factory.
5. The stator is held in the
housing with a bolted-in clamp
ring.
6. After ring is removed, turn
housing upright and bump on
hardwood blocks. This should
jar the stator loose and allow it
to drop out.
7. Thoroughly clean housing
before replacing new stator.
Replace stator and make all
wire connections to connection
box before replacing housing
on pump. This is important as
leads must be tucked behind
the windings by using hands
up through rotor core.
IMPORTANT: Use only
compression type insulated
connectors on the wires. Do not
tape leads as oil will deteriorate
the tape and cause damage to
stator and bearings.
8. Drain oil from chamber.
If oil is clean and no water is
present, seals can be considered
satisfactory to reuse.
9. Check top bearing. If clean and
does not turn rough, bearings
can be reused and it is not
necessary to completely
dismantle pump to change
bearings. If bearings are
damaged with dirt or heat,
they must be replaced. See
additional instructions on
replacing seals and bearings.
Remember to reinstall the
upper bearing load spring.
10.Replace stator housing onto
seal chamber and bolt in place.
Be sure seal failure wire is
connected before housing is
assembled.
Be sure O-ring seal has been
replaced. If O-ring is nicked
or cut, replace with new rings.
This applies to all O-rings used
in assembly.
11.After all leads are reconnected
in the connection box, make a
high voltage ground test on
each wire. The only wire that
should show ground is the
green power lead and the
ground lead in the auxiliary
control cable.
12.For safety, complete pump
should be air checked under
water for leaks. If seals were
OK, refill seal chamber with
oil. Lay pump on side for this
oil filling with oil fill hole
upright. Do not completely fill;
leave oil about 1 inch below
plug hole. Use only high grade
transformer oil or regular
Hydromatic submersible oil in
this chamber. Replace plug;
use Permatex on threads.
Install air valve in top plug
opening of motor housing and
charge housing with about
10 psi of air. Be sure air is dry.
Do not use air line where water

Pump
Maintenance
may be trapped in the line.
Submerge complete unit under
water and check for leaks.
13.Refill motor chamber with oil.
Use high grade transformer
oil or Hydromatic special
submersible oil. Fill chamber
until oil covers top of the
windings. Leave air space in
the top for expansion. Use
Permatex on plug threads.
Replacing Seals and Bearings:
1. Drain all oil from motor
chamber and seal chamber
as described.
2. Remove motor housing as
described.
3. Remove bolts that hold seal
chamber to pump housing. Use
back-off screws to break loose.
With hardwood block, tape end
of impeller to loosen from
shaft. When free, remove
impeller from shaft.
4. Lift rotating assembly (rotor,
shaft and impeller) from pump
case and place horizontally on
bench.
5. Impeller removal – Hold motor
and remove bolt and washer
from impeller end of shaft.
Impeller is threaded to the
shaft, so tap face of impeller
with hardwood block to free
threads. Holding rotor, turn
impeller with hardwood block
to free threads. Holding rotor,
turn impeller counterclockwise
as thread is right-hand.
6. Shaft sleeves are not used.
7. Remove lower seal spring and
pry out seal with screwdriver.
8. To remove seal housing, take
out socket head bolts and using
bolts in back of holes, pry
plates loose. This will force
out the lower seal if not
already removed.
9. Remove snap ring that holds
upper seal. Pull seal if it is free.
If not free, it can be forced off
when shaft is removed.
10.Remove 4 bolts that hold
bearing housing in place. Set
assembly in upright position
and bump end of shaft on
hardwood block. This will
push the bearing from the
housing and will force upper
seal from shaft.
11.Use bearing puller to remove
bearings. Replace with new
bearings. Press only on inner
face of bearing when
replacing. Pressing on outer
face can damage the bearing.
Bearings are standard size that
can be obtained from any
bearing supply house or
can be obtained from the
Hydromatic factory.
12.IMPORTANT: Do not use
any of the old seal parts.
Replace with all new seals.
13.Thoroughly clean all castings
before replacing seals. One
grain of dirt between the seal
faces can cause failure.
14.Examine all O-rings for nicks
before using.
15.Use Locktite on socket head
locking screw in end of shaft.
16.Before refilling chamber with
oil, air test as described above.
17.Refill both chambers with oil
as described above.
18.Always check all leads with
high voltage or with Megger
for grounds before operating
the pump.

Pump
Maintenance
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.
Below is a list of common
problems and the probable
causes:
Pump will not start.
1. No power to the motor.
Check for blown fuse or open
circuit breaker.
2. Selector switch may be in the
Off position.
3. Control circuit transformer
fuse may be blown.
4. Overload heater on starter may
be tripped. Push to reset.
Pump will not start
and overload heaters trip.
1. Turn off power and check
motor leads with Megger or
ohmmeter for possible ground.
2. Check resistance of motor
windings. All 3 phases should
show the same reading.
3. If no grounds exist and the
motor windings check OK,
remove pump from sump
and check for clogged or
blocked impeller.
Pump operates with selector
switch in Hand position but will
not operate in Auto position.
1. This indicates trouble in the
float level control or the
alternator relay.
2. To check for defective float
control, put selector switch in
Auto position and turn off
main power. Put a jump wire
on terminal strip. Turn on
power and if pump starts,
trouble is in float control.
Replace control.
Pump runs but will not shut off.
1. Pump may be air locked.
Turn pump off and let set for
several minutes, then restart.
2. Lower float control may be
hung-up in the closed position.
Check in sump to be sure
control is free.
3. Selector switch may be in the
Hand position.
Pump does not deliver proper
capacity.
1. Discharge gate valve may be
partially closed or partially
clogged.
2. Check valve may be partially
clogged. Raise level up and
down to clear.
3. Pump may be running in
wrong direction. Low speed
pumps can operate in reverse
direction without much noise
or vibration.
4. Discharge head may be too
high. Check total head with
gauge when pump is operating.
Total head is discharge gauge
pressure converted to feet plus
vertical height from water level
in sump to center line of pres-
sure gauge in discharge line.
Gauge should be installed on
pump side of all valves.
Multiply gauge pressure in
pounds by 2.31 to get head
in feet.
5. If pump has been in service for
some time and capacity falls
off, remove pump and check
for wear or clogged impeller.
Motor stops and then restarts
after short period, but overload
heaters in starter do not trip.
1. This indicates heat sensors in
the motor are tripping due to
excessive heat. Impeller may
be partially clogged giving
a sustained overload but not
high enough to trip overload
heater switch.
2. Motor may be operating out of
liquid due to a failed level
control. All Hydromatic
S4HRC submersible motors
can operate for extended
periods out of water without
burning up the winding, but the
heat sensors give motor
prolonged life by controlling
winding temperature.
3. Pump may be operating on a
short cycle due to sump
being too small or from water
returning to sump due to a
leaking check valve.
