General
Information
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.
Pump Cautions
And Warnings
DO NOT connect conduit to
pump. Electrical installations
shall be in accordance with
the National Electrical Code
and all applicable local codes
and ordinances. This marking
is required on 3 phase
models only.
7. CAUTION - For use with
maximum 140°F water.
8. CAUTION - Tank should be
vented in accordance with
local plumbing codes and
should not be installed
in locations classified as
hazardous, in accordance with
the National Electrical Code,
ANSI/NFPA 70-1999.
9. CAUTION - Risk of electrical
shock. Do not remove cord and
strain relief. Do not connect
conduit to pump.
10.WARNING - Severe injury
may result from accidental
contact with moving cutters.
Keep clothing, hands and feet
away from cutters any time
power is connected to the pump.
11.CAUTION - Never work on
pump with power on. Make
sure that the ground wire is
securely connected and that the
unit is properly grounded in
accordance with local codes.
Pump
Installation

3
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 that the Hydromatic nonclog
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
Megger after the connections are
made. This is important, as one
grounded wire can cause
considerable trouble.
1. Grinder 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.
5. Level control should be set so
that pump turns off when level
is about 2 inches above inlet
of pump suction and turns on
when level is about 2 inches
above motor.
6. If problems occur check power
source. Make sure a separate
supply line is available. Verify
voltage supply.
7. Check resistance of windings.
(See Chart, page 5.) If not
within guidelines, return pump
to authorized Hydromatic
service or repair center.
As the motors are oil filled, no
lubrication or other maintenance
is required. Pump should be
checked every quarter for
corrosion and wear.
Starting the Pump:
WARNING: Severe injury may
result from accidental contact
with moving cutters. Keep
clothing, hands and feet away
from cutters any time power is
connected to the pump.
To start the pump, perform the
following steps in order:
Pump
Servicing
connected and that the unit
is properly grounded in
accordance with local codes.
CAUTION: Severe injury may
result from accidental contact
with moving cutters. Keep
clothing, hands and feet away
from cutters any time power is
connected to the pump.
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 screws (17) and
remove cutter ring retainer
(16). Stationary cutter (15)
cannot be removed from volute
(20).
5. Unscrew hex head cap screws
(12) and remove volute
case (20).
6. Radial cutter (13) and axial
cutter (14) 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 screw (19),
washer (18), and radial cutter
(13) from shaft. Radial cutter
(13) and impeller (9) are
screwed onto shaft. The thread
is right-hand. Tap radial cutter
(13) with plastic hammer if
necessary to loosen. Axial
Pump
Operation
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.
CAUTION: Never work on
pump with power on. Make sure
that the ground wire is securely

4
cutter (14) lifts off impeller (9)
and is held from rotation by
pin. Unscrew impeller (9) from
shaft in same manner as
radial cutter (13).
8. Clean all parts thoroughly
before proceeding with
assembly. Replace case (20),
but do not replace cutter ring
(15) at this point.
9. Replace cutter ring (15) and
cutter ring retainer (16). Screw
down with screws (17).
10.Plug pump into power and
operate for a few seconds only
to ensure parts are not rubbing.
Replacing Seal:
1. Drain the oil from the pump by
removing the fill plug (5)
located on the side of the
motor housing (7).
2. Remove the volute and cutters
per the instructions listed
under the replacing grinder
parts section in this manual.
3. To remove the impeller (9),
secure the shaft by a flat
bladed screwdriver into slot on
end of the shaft. Hold a wood
block against the impeller vane
and tap it with a hammer until
it spins off.
4. Remove the seal (24) rotating
elements by sliding the spring
bellows off the shaft, then
using two screwdrivers, slide
the carbon seal assembly off
by prying on the retaining ring.
5. Using a screwdriver, break the
old stationary portion of the
seal (24) to allow for removal.
6. Take the stationary portion of
the new seal (24), and lube the
rubber material with good
quality dielectric oil. Press
the stationary portion of the
new seal into the seal/bearing
plate (21).
CAUTION: Do not reuse old
seal parts. Replace all parts
with new. Mixing old and new
parts could cause immediate
seal failure.
7. Using a good quality dielectric
oil, lube the rubber material on
the carbon seal assembly (24)
and press it on the shaft. Place
the spring bellows on the shaft
as removed.
8. Using a pressure gauge with a
fill stem, pressurize the motor
housing no more than 7 psig
with dried air and check for
leaks. If after several minutes
the gauge reads the same,
the seal is good and you can
continue with assembly.
NOTE: It is normal to observe
some air bubbles in the seal
area initially as the seal seats. If
bubbles do not stop within a few
seconds, the seal is either not
properly installed or is damaged.
9. Reassemble the cutter and
volute as outlined in the
replacing grinder parts section
of this manual.
10.Refill motor housing with
a good quality paraffinic
oil (25). Fill the motor housing
so that the tops of the motor
windings have been covered,
but leave an air gap to allow
for expansion of the oil.
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.
WARNING: Severe injury may
result from accidental contact
with moving cutters. Keep
clothing, hands and feet away
from cutters any time power
is connected to the pump.
