Warning

7. For proper automatic operation,

make sure the pump power

cord is plugged into the

piggyback receptacle on the

diaphragm switch cord.

8. Connect to separate electrical

circuit taken directly from

main switch.

9. Use steel or plastic pipe for all

Pump

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 competent electricians

should make the installations.

Servicing should be performed

only by knowledgeable pump

service contractors or authorized

service stations.

WARNING: Always disconnect

the pump from power source

before handling or making any

adjustments. Always wear

rubber boots when there is

water on the floor and you must

unplug the pump or make any

adjustments.

1. Removing pump from sump.

Before removing pump from

sump for repair, check to see if

the trouble could simply be a

blown fuse, tripped circuit

breaker, or a power cord not

completely inserted into the

receptacle.

NOTE: Automatic thermal

overload protects the

sealed-in oil motor. Running

dry may overheat the motor

and activate the overload

protector. This will close the

circuit when the motor cools

and allow pump to restart. If

condition continues to exist,

it may cause premature pump

failure.

Unplug the power cord and

pull the pump, by the handle,

from the sump. Sandblast, if

possible, any dirt or trash from

the outside of the pump before

dismantling.

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 the new assembly.

3. Check for impeller blockage.

Check for an obstruction in the

impeller cavity by laying the

pump on its side and inserting

a screwdriver through the hole

in the foot and baffle plate (28)

and the bottom plate (26) and

turning the rotor and shaft

(16). It should turn freely. If

the impeller hangs up or there

is an indication of impeller

blockage, the foot and baffle

plate must be removed by

removing the three hex head

cap screws (29) and the

bottom plate removed by

removing the five hex head

cap screws (27). Clear

the impeller of its obstruction

and clean the impeller,

and reassemble.

4. Check power cord. Check the

power cord (5) for brittleness

or for any cuts or nicks in

the insulation. Using an

ohmmeter, check the

continuity of the power cord.

If any of these tests fail, the

power cord should be

replaced. To replace power

cord, unscrew the nut on the

cord, pull cord up and discard

damaged power cord. Add

pipe sealant to threads and

reinstall by pushing cord onto

pins and tighten nut.

5. Check for air lock. A sump

pump is said to be air locked if

water traps in the pump and it

cannot get out, thus preventing

pump from operating.

TOTAL DYNAMIC HEAD-FEET

010 20 30 40 50 60

CAPACITY–U.S. G.P.M.

1/2 HP

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.

6. Check the oil. Remove the

pipe plug (4) in the top of the

motor cover and 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 (23, 24), seal ring (20),

or cord nut.

7. Remove the motor cover.

Remove the four hex head cap

screws (22). Use a screwdriver

to pry the motor cover (19)

from the volute case (21) at the

fastening ears, being careful

not to cut the seal ring (20)

with the screwdriver or

crack the motor cover. Lift

the motor cover until it clears

the stator (15).

8. Check for short. Disconnect

the stator leads (7, 8, 9) from

the connector (6). Use an

ohmmeter to check the

continuity of the stator. If

stator fails to pass the

continuity test, it must

be replaced.

9. Remove the stator. To remove

the stator, remove the four hex

head screws (12) and the stator

plate (13). Lift the stator off

the volute case (21) and

set aside.

10.Remove the impeller. To

remove the impeller (25), hold

the rotor (16) in your hand

and tap the impeller with

a plastic or rubber mallet

so as to turn the impeller

counterclockwise.

11.Check the seal. Remove the

rotating portion of seal (24)

from shaft by inserting a

screwdriver under the edge of

the seal and lifting it off

without damaging seal. Inspect

the seal face for any nicks or

an uneven seating of seal face.

If any are present, replace the

seal. (See Step 14.)

12.Remove rotor and shaft. Tap

the rotor shaft (16) at the

impeller end of the shaft with a

plastic mallet to remove the

rotor and shaft. Inspect the

bearings (17). If they do not

rotate freely and smoothly,

they should be replaced. When

new bearings are ready to be

added onto the shaft, do not

push on outer face of bearings.

This will damage bearings. If a

rotor and shaft are ordered

from Hydromatic, the bearings

will be supplied already

pressed on the shaft.

Pump

Servicing

Do not fill the motor housing

completely — allow airspace

for oil expansion.

21.Reinstall oil pipe plug. Coat

pipe threads with thread

sealant before installing.

22.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.

18.Reinstall the stator. Place the

stator (15) in the volute case

(21) so the stator bolt holes

line up. Lay the stator plate

(13) on the stator (15) and line

up with stator bolt holes. Put in

the stator bolts (12) and tighten

evenly to prevent cocking of

the stator. Push the connectors

of the power cord onto the

stator terminals.

19.Reinstall motor housing.

Tighten down the four hex

head cap screws (22) evenly

to prevent cocking of motor

housing and achieving an

uneven seal on the seal

ring (20).

20.Oil. Fill the motor cap with

high grade transformer oil such

as WOCO Premium 100 oil or

equivalent to at least 1⁄4" over

motor windings (.54 gallon).

13.Remove seal. Remove the old

stationary portion of the seal

(23) from the case (21) by

inserting a screwdriver into the

seal housing of the case from

the top of the case and tapping

lightly with a hammer. Clean

the seal area of the case with a

clean cloth.

14.Reinstall the rotor and shaft

assembly. Push on outer face

to seat bearing in volute case.

15.Reinstall seal. Apply an oil

lubricant to the new stationary

portion of the seal (23) and

press into the case (21). Coat

the new rotating portion of seal

with lubricant and press

into place on the rotor shaft

with the rubber ring facing

the impeller.

16.Reinstall impeller. Add a drop

of Locktite 277 to the shaft

and screw the impeller on

hand tight. The impeller will

force the rotating portion of

seal into position.

17.Replace seal ring. Remove

the old square seal ring (20)

from the volute and stretch

on a new ring coated with

O-ring lube.

Do not roll the ring onto the

volute or improper seating and

water leakage into the motor

housing will result.
