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

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.

ground pin from electrical

plug. Do not use an

extension cord.

9. For proper automatic operation

(Model SP40A1 or SP40A2)

make sure the pump power

SP40

Typical Installation

cord is plugged into the back

of the piggyback receptacle on

the diaphragm switch cord.

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.

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.

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.

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.

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.
