Description
This self-priming portable utility pump is
designed to be used as a transfer pump
for such applications as emptying water
heaters, swimming pools, livestock tanks,
boats, etc. Pump can also be used for an
intermittent pressure boost for applications such as washing cars, cleaning driveways, etc. The motor is air cooled; it is
not designed to operate under water.
NOTE: This pump is not intended for
permanent installation or long, extended periods of continuous operation.

Operating Instructions and Parts Manual EC50
General Safety
Information
Do not submerge
motor or allow
motor to be exposed to water. Personal
injury and/or death could result.
Do not use to pump flammable or explosive fluids
such as gasoline, fuel oil,
kerosene, etc. Do not use in
a flammable and/or explosive atmosphere. Pump should only be used to
pump clear water. Personal injury and/or
death could result.
Risk of electrical
shock. All wiring
must be performed by a qualified electrician.
Do not walk on wet areas
until all power is turned
off. Failure to follow this
warning could result in
fatal electrical shock.
1. Read all instructions before
operation.
2. Disconnect power and release all
pressure within the system before
servicing any component.
3. Drain all liquids from system before
servicing.
Secure the dis-
charge line before
starting the pump. An unsecured dis-
321304-002 1/07
charge line may whip. Personal injury
and/or property damage could result.
4. Periodically inspect pump and system components, checking for
weak and/or worn hoses. Insure all
connections are secure.
5. Provide a means of pressure relief
in the case of an obstructed discharge line.
6. Protect electrical cord from sharp
objects, hot surfaces, oil and chemicals. Avoid kinking the cord and
replace damaged cords immediately.
Installation
Always disconnect power
source before attempting
to install, service, or maintain the pump. Never handle a pump with wet hands or when
standing on wet or damp surface or in
water. Fatal electrical shock could occur.
1. A ground fault circuit interrupter
(GFCI) is required.
Risk of fatal electrical
shock! This pump is supplied with a grounding
conductor and grounding
type attachment plug. A grounded
receptacle in conformance with current
NEC and local codes must be used (See
Figure 1).

Operating Instructions and Parts Manual
Installation
(Continued)
2. This pump operates on 120V, 60 Hz
AC, single phase or 120V DC.
3. Use an extension cord only if necessary. Follow the Extension Cord
Length Table for proper gage of 3wire, grounding type extension cord.
Risk of fatal electrical
shock! Never cut off the
round grounding prong.
Cutting the cord or plug
will void the warranty and make the
pump inoperable.
4. Figure 2 shows a typical installation.
Threaded adapters are furnished for
attaching garden hose where conditions permit its use. In no case should
the pump be more than 15 feet above
or away from inlet source. Install a
foot valve and when suction lift is
over 10 feet or when suction line is
over 10 feet.
5. The inlet line may be galvanized pipe,
plastic pipe, or reinforced hose. Small
leaks in suction line greatly reduce
efficiency of pump and may prevent
priming.
Ordinary garden
hose will collapse
under suction pressure and should not be
used in the inlet but for pressure boosting
only.
6. Use a strainer when pumping from a
creek, pond, or source where foreign
objects may be sucked into the pump.
The strainer should prevent solids
from entering the inlet line.
7. A regular garden hose may be used as
a discharge line.
Operation
Pump must be
filled with water
before operation. Running the pump dry
will cause damage to the shaft seal.
1. This unit is not waterproof or weath-
erproof and is not intended to be
used in showers, saunas, or other
potentially wet locations. The motor
is designed to be used in a clean,
dry location with access to adequate
cooling air. Ambient temperatures
around the motor should not
exceed 104˚F (40˚C).
2. Remove priming plug and fill with
water. Close plug
3. Plug power cord into GFCI protected
electrical outlet. The pump will
prime in a few minutes depending
on suction line length. Use of foot
valve on suction line is recommended.
4. In the case of pressure boosting,
turn water on before starting pump.
This force primes the pump. Then,
plug power cord into GFCI protected electrical outlet.
5. Unplug cord to turn unit off.
Maintenance
Let pump cool for
at least 20 minutes
before attempting to service. Motor may
be extremely hot. Personal injury may
result.
1. Pump should be checked periodically
for proper operation.
Always disconnect
the electrical supply
before attempting to install, service, or
perform any maintenance. If the power
source is out of sight, lock and tag in the
open (off) position to prevent unexpected
power application. Failure to do so could
result in fatal electrical shock. Only qualified electricians should repair this unit.
Improper repair could result in fatal electrical shock.
BRUSH REPLACEMENT
Brushes for this
pump should be
inspected after 100 hours of operation.
Pumps with excess of 100 hours of operation may stop operating or fail to start.
This could be due to worn brushes or carbon build-up. The brushes should be
removed and carbon removed. Worn
brushes are not covered under warranty.
Replacement brushes may be available
from Blue Angel Pumps. Call
1-888-636-6628 to order.
1) Disconnect electrical cord from power
supply.
2) Remove brush caps with screwdriver.
3) Remove old brush assembly.
4) Insert new brush assembly.
5) Replace brush caps.
ADDITIONAL REPAIRS
For other problems, consult troubleshooting chart.
To replace bearings, shaft seal, gaskets,
rotor, follow the instructions listed below.
1. Disconnect electrical cord from
power supply.

15. Press shaft seal into backhead. When
pressing shaft seal into place, apply
force to the cup flange. Avoid touching the polished seal surface; oil or
scratches on this surface may cause
premature failure of the seal.
16. Press ceramic side of seal into
impeller, ceramic side out. Avoid
touching ceramic with hands as oil
may cause premature failure of the
seal. Wipe oil off both sides of seal
with a soft, lint-free cloth.
17. Reassemble unit in reverse order,
beginning with step 9.
18. After reassembly check shaft for free
rotation with screwdriver in fan
through air exit openings.

Maintenance
(Continued)
2. Relieve pressure in system.
3. Disconnect inlet and outlet lines.
4. Empty water from pump housing.
5. Place pump on bench with motor end
up and remove brushes as described
in BRUSH REPLACEMENT instructions. If brushes are to be reused,
mark the location from which each
came. Replace brushes in original orientation upon completion of repair.
6. Remove the four cap screws holding
motor housing and pump housing
together. Motor housing is now free
and can be removed. Take care not to
lose commutator bearing finger
spring.
7. With a screwdriver, pry the rotorbackhead assembly out of the pump
housing.
8. Remove the impeller by turning
counter clockwise (righthand thread
on shaft). Save any washers which
were between impeller hub and
shaft.
9. Remove backhead (the bearing is
press fit into the backhead).
10. Place backhead on flat surface with
impeller side down and press out
shaft seal.
11. Place impeller on flat surface with
vane side down and with screwdriver
and hammer break ceramic seal ring
into several pieces and remove. Next,
remove rubber seal ring cup from
impeller.
12. Remove bearings from armature shaft
(press-fit on shaft).
13. Inspect the armature commutator
bars. The environment in which the
unit has been operating will have
influence on the condition of the
commutator. Airborne dust an dirt
will accelerate wear. A rough or
scarred appearance may dictate having commutator reconditioned before
reassembly.
14. To reassemble, install new bearings on
the shaft. Always press against the
inner race to prevent bearing damage. Make sure bearings are tight
against the shaft shoulders.
