General
Information
Pump
Warning
4. 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.
5. 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.
6. A check valve should be
installed in discharge pipe, at
least 12” above the discharge
outlet of the pump.
7. An audible alarm system, such
as the Q Alert, for high
water conditions should be
installed in every pump for
greater protection.
NOTE: Q Alert alarm is
for indoor use only. Contact
your Hydromatic distributor
for other panel applications.
WARNING: When using
the automatic diaphragm
switch the vent tube in
the plug must be clear of
obstructions.
Do not bend cord. This will
cause a crimp in the vent tube
and switch failure will occur.
Pump should be plugged into
a single outlet, where vent
tube can “breathe.” Blocking
tube or bending cord will void
the warranty.
8. Connect to power source
using 3-prong grounded
AC receptacle. Do not
remove ground pin from
electrical plug. Do not use an
extension cord.
Pump
Installation
These important instructions
must be followed for satisfactory
performance of your pump.
Before installation, check
your local electrical and
plumbing codes.
1. Provide proper sump size
to allow the pump to
operate without restrictions. A
two- to five-minute run time is
recommended. Also, minimum
24” diameter recommended.
2. Make sure sump is free of
string, cloth, nails, gravel, etc.
before installing pump.
3. Do not set pump directly on
the bottom of sump pit if it
is not solid. Raise the pump
by placing bricks or concrete
blocks underneath it.

9. For proper automatic operation
(Model SP40A1 or SP40A2)
make sure the pump power
cord is plugged into the back
of the piggyback receptacle on
the diaphragm switch cord.

SP40
Typical Installation
10.Use pump partially or
completely submerged for
pumping (temperature to
140° F). The SP40 will
pump solid materials up to
1-1⁄4” (spherical) in diameter.
CAUTION: Do not pump
flammable liquids, strong
chemicals or salt water.

Pump
Servicing
Servicing should be performed
only by knowledgeable pump
service contractors or authorized
service stations.
1. Remove pump from sump.
Before removing pump from
sump pit for repair, check if
the trouble could simply be
a blown fuse, tripped circuit
breaker, or a power cord
not completely inserted into
the receptacle.
2. Check diaphragm switch. If
the unit is being operated
by the automatic diaphragm
switch, unplug the pump from
the piggyback receptacle
and plug the pump directly into
the power source. If the pump
starts each time it is plugged
directly into the receptacle
and does not start each
time when plugged into the
piggyback switch with
the diaphragm switch pressed
into a start position, replace
the complete piggyback
switch assembly and retest
with new assembly.
3. Check for impeller blockage.
Disconnect pump and switch
from power source. Check for
an obstruction in the impeller
cavity by laying the pump on its
side and inserting a screwdriver
into impeller. Impeller should
turn freely. If impeller is
stuck, then turn the pump on
its side, DRAIN THE OIL
through the oil fill plug on top
of the pump. Drain oil into a
clean, dry container. A milky
appearance to the oil indicates
that water has entered through
either worn out or damaged
seals (7) or seal ring. Remove
the 4 screws (6) to remove the
volute (9). If the impeller (10)
does not rotate freely, clear the
impeller and cavity walls before
reassembling the base. Repeat
Step 2.
4. Check power cord. If the
above tests have not resolved
the problem, it may be in the
electrical components of the
pump. Starting with the power
cord (2), inspect for cuts or
nicks in the insulation. If the
cord is damaged – replace it!
5. Remove the motor cover. Use
a screwdriver to pry the motor
cover (3) from the seal plate
(8) at the fastening ears, being
careful not to cut the seal ring
with the screwdriver or crack
the motor cover. Lift the motor
cover until it clears the stator
(4).
6. Check for short. Disconnect
the stator leads from the
connector. Use an ohmmeter
to check the continuity of the
stator. If stator fails to pass the
continuity test, it must
be replaced.
Ground check. Set ohmmeter
scale pointer to R X 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.
Always make this test with the
meter when scale pointer is set
to a new scale before making
any checks on motor.
Now connect one meter lead
to one blade terminal of stator
and touch other meter lead
to motor stator shell (4). If
needle reads below 5 (500,000
ohms) stator must be dried out
before reusing. To dry out,
bake in 220° oven for 4 hours.
Recheck after motor cools. If
motor is new or thoroughly
dry, needle of ohmmeter will
not move on the ground test.
This indicates a reading of
50 megohms or higher. One
megohm is one million ohms.
6100 1009

5
When making the ground test,
if the needle goes clear to zero
the motor probably has a wire
touching the stator at some
point and the stator will have
to be replaced.
Winding resistance test. If
motor shows a satisfactory
ground test, then the winding
resistance must be checked.
Use ohmmeter with scale
pointer set on R X 1 scale. On
this scale meter reads directly
on ohms. Always check the
meter with leads together as
described above under ground
test before making a reading of
the winding.
Connect one meter lead to each
of the black terminal leads.
Meter should read about 1.9
ohms. This is the resistance
of the main winding for a 115
volt stator. This reading for
a 230 volt stator should be
about 7.7 ohms.
Now remove the capacitor and
connect one meter lead to each
of the brown wire terminals.
The meter should read about
12 ohms for a 115 volt stator.
For a 230 volt stator this
reading should be 21.3 ohms.
This is the resistance of the
start winding.
7. Remove the stator. To remove
the stator, remove the four
hex head screws and
disconnect the brown capacitor
leads from the capacitor and
remove the stator plate with
the capacitor. Lift the stator off
the seal plate (8) and set aside.
8. Remove the impeller. To
remove the impeller (10),
hold the motorshaft (5) with a
screwdriver at the center of the
impeller and tap the impeller
with a plastic or rubber mallet
so as to turn the impeller
counterclockwise.
9. Check the seal. Remove
the rotating portion of seal
(6) from shaft by inserting a
screwdriver under the edge
of the seal and lifting it off.
Inspect the seal face for any
nicks or an uneven seating of
seal face. If any are present,
replace the seal.
(See Step 14.)

Pump
Servicing
19.Reinstall oil pipe plug. Coat
pipe threads with thread
sealant before installing. Plug
into housing (3).
20.Check pump. Plug the power
cord into a grounded outlet
and start pump by applying
pressure to the switch
diaphragm (automatic only
– manual should start when
power is applied). Motor
should run smoothly, be free
of vibration and stop when
pressure is removed from
diaphragm switch.
21.Check for air lock.
Hydromaticpumpshaveasmall
air vent hole in the impeller
cavitytoletouttrappedair.Ifthis
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.
15.Replace seal ring. Remove the
old square seal ring from the
seal plate and stretch on a new
ring coated with O-ring lube.
Do not roll the ring onto
the seal plate or improper
seating and water leakage into
the motor housing will result.
16.Reinstall the stator. Place the
stator (4) in the seal plate (8)
so the stator bolt holes line
up. Lay the stator plate on
the stator (4) and line up with
stator bolt holes. Put in the
stator bolts and tighten evenly
to prevent cocking of the
stator. Connect the capacitor
to the capacitor leads. Push the
connectors of the two black
stator leads onto the power
cord spade terminals.
17.Reassemble pump. Replace the
motor cover (3) on the seal
plate (8). Place the assembly
on the volute (9). Insert the
four cap screws (6) through
the motor housing ears, into
the tapped holes in the volute.
Tighten them evenly to prevent
cocking the motor housing and
causing an uneven seal on the
seal ring.
18.Oil. Fill the motor cap with
high grade transformer oil just
covering over stator end cap
(.45 gallon).
Do not fill the motor housing
completely – allow airspace
for oil expansion. Make sure
the stator and capacitor are
fully immersed. You will have
to peer through the oil plug
hole to be sure of the correct
oil level.
10.Remove rotor and shaft.
Tap the rotor shaft (5) at the
impeller end of the shaft with
a plastic mallet to remove the
rotor and shaft. Inspect the
bearings. If they do not rotate
freely and smoothly, they
should be replaced.
11.Remove seal. Remove the
old stationary portion of the
seal (7) from the seal plate by
inserting a screwdriver into the
seal housing of the seal plate
from the top of the case and
tapping lightly with a hammer.
Clean the seal area of the seal
plate (8) with a clean cloth.
12.Reinstall the rotor and shaft
assembly. Push on outer face
to seat bearing in seal plate.
13.Reinstall seal. Apply a
good lubricant to the new
stationary portion of the
seal (7) and press into the
seal plate. Coat the new
rotating portion of seal with
lubricant and press into
place on the rotor shaft with
the rubber ring facing
the impeller.
14.Reinstall impeller.Add a
drop of Locktite 222 to the
shaft and screw the impeller on
hand tight. The impeller will
force the rotating portion of
seal into position.
