Safety hazard
Danger of electric shock
Danger of damaging the pump
• The series of products EEMQ, ENMQ, ALMQ, ENTQ and ALTQ are
partly completed machinery identical, respectively, to the machinery of
series EEM, ENM, ALM, ENT and ALT, except for the fact that they are
supplied without the switch and cable for connection to the power
supply but provided with an electrical terminal block. In the rest of the
manual, reference will only be made to the series without the suffix –Q.
When switch and cable are mentioned this refers to the completed
machinery, while when terminal block is mentioned this refers to the
corresponding partly completed machinery.
• The term “series ALCC” refers to the pumps AL 12/20, AL 24/20, AL
12/25, AL 24/25, AL 24/40.
• The type of power supply is indicated in the box identified by the word
“Motor” in the pump ratings plate. 1~ means “single-phase alternating
current”, 3~ means “three-phase alternating current” and
means “direct current”.
2 – USE OF THE MACHINERY/PARTLY COMPLETED
MACHINERY
The machinery or partly completed machinery is a self-priming pump of
“side channel” type. It has been designed and manufactured specifically
for transferring and handling liquids, thanks to some important features:
very rapid self-priming capacity, i.e. suction of air contained in the suction
hose to start pumping;
no damage to the pump if the liquid in the suction tank finishes;
possibility of reversing the flow of liquid (for models supplied with
alternating current).
Although it has been designed for professional use, it can also be used in
a domestic environment, providing the user has become acquainted with
its use, by carefully reading the instructions contained in this manual.
2.1 – PROPERTIES OF PUMPED LIQUID
the liquid to be pumped:
- must have no hard suspended particles (sand, gravel, etc.) which can
cause rapid wear of internal parts. If the liquid to be pumped has this risk
factor, install a suitable filter in the suction hose.
- must not be aggressive towards the materials with which it comes
into contact, i.e.:
1) the material forming the pumping body (brass for series EEM, ENM,
ENT, ECC - AISI 316 stainless steel for series AL);
2) the material of which the shaft is manufactured (AISI 316 stainless
steel);
3) the materials of which the gasket and the sealing device are
manufactured (see Chapter 3.5).
4) (only for models with by-pass) acetalic resin.
- must have suitable viscosity: these pumps are not suitable for very
viscous liquids (such as honey). For series ENM, ENT, ALM, ALT pumps,
consider as an indication of maximum viscosity a mineral oil type SAE 30
at a temperature of 40° C; all other series are suitable for liquids with
viscosity similar to water.
- must have a maximum fluid density of: for series ENM, ENT, ALM,
ALT pumps: 1.1 g/cm3; for other series: density similar to water.
- must have a minimum temperature of: -15°C, in any case above the
freezing temperature of the liquid to be pumped.
WARNING
WARNING

38
- must have a maximum temperature of: models without by-pass:
depending on the rubber used to manufacture the gaskets: 90°C (NBR
rubber, which is standard unless otherwise indicated on the pump), 110°C
(EPDM rubber), 130° C Viton rubber; models with by-pass: 90°C.
Examples of use of the series with brass pump body (series EEM,
ENM, ENT, ECC)
Water, sea water, gas oil, oil, soaps; in the European Union pumps with
brass pumping body are generally not considered suitable for use with
food products, such as milk or olive oil (ref. standard UNI EN 13951).
Application in the food sector is subordinate to checking suitability of the
pumps with the provisions of the specific HACCP plan drawn up by the
user.
Examples of use of series with AISI 316 stainless steel pump body,
material suitable for foods and with excellent resistance to corrosion
and abrasion (series AL)
- liquid foods, such as wine, vinegar, olive oil, milk; for these uses
appropriate methods of washing and disinfecting the pump must be
adopted, according to type of liquid (see Chapter 4.3);
- compatible corrosive liquids (such as fungicides or liquid fertilizers)
- the same liquids permitted for brass pumps, in this case ensuring a much
longer useful life.
Use of the pump in environments in which there is danger
of explosion or fire (as defined by the law) is prohibited; in
particular, do not use with petrol, acetone, solvents, etc.
2.2 – ENVIRONMENT OF USE
- Ventilated, clean and dry closed environment.
- Normal or marine atmosphere, ambient temperature between –15 °C
and 40 °C and maximum relative humidity 80%.
- Maximum installation altitude: 1000 meters above sea level.
3 – TECHNICAL DESCRIPTION
3.1 - SPECIFICATIONS
The pump can perform suction of liquid from one port (suction port),
sending it to the other port (discharge port); the essential parameter
characterizing a pump is capacity Q (quantity of liquid transferred in a
given time); the speed of the pumping operation depends on this.
The capacity of a pump is not fixed, but depends on the total manometric
head H required by the installation, which is the sum of two contributions:
1) difference in height (measured vertically) between the level of liquid in
the tank of destination and that of the tank or origin;
2) energy losses caused by liquid flow in pipes, valves, fittings, and other
elements inserted along its path.
Tab. A indicates the capacity (in litres per minute) as a function of total
manometric head (in metres) for the various pump types. The same table
also indicates the value of the maximum head Hmax developed by the
pump (expressed in bar, unit of pressure measurement), which is reached
when the discharge port is closed, and the maximum equivalent A-
weighted sound pressure level (LeqA) obtained at 1 metre from the
surface of the pump operating with water at 20°C.

3.3 – MAXIMUM PRIMING HEIGHT
The maximum priming height is the maximum difference in level between
the pump and the level of the liquid to be pumped with which it can
perform suction of air from the suction hose and start pumping.
With water at 20°C this value can reach 6 metres, but it depends on the
quantity of liquid present inside the pump during priming; this quantity
depends on the installation methods of the pump and on the configuration
of the hoses. To achieve maximum priming performances, comply with the
following installation measures:
1) Discharge hose: during priming the liquid contained in the pump is
pushed outwards through the discharge port; therefore, the quantity of
liquid decreases, causing reduced priming; avoid this by positioning the
discharge hose so that liquid that has flowed out returns inside the pump,
for example, by pointing the initial part upwards with a difference in level of
50 cm.
2) Suction hose: the initial part pointing upwards with a difference in level
of 20 cm increases the quantity of liquid that remains inside the pump after
it is stopped.
3.4 – PUMPING DIRECTION
Pumps with alternating current motor are two-way: by reversing the
direction of rotation of the motor the direction of liquid flow is reversed. For
this purpose, machines are equipped with a 3-way switch: 0 = off, 1 = on,
2 = on with liquid flowing in the opposite direction to position 1. The typical
pumping directions in single-phase machinery are described in Fig. 8,
lines 2 and 3. In three-phase machinery the direction depends on the
connection to the power supply.
In direct current partly completed machinery, the pumping direction is fixed
and is unrelated to connection of the power supply cables to the terminal
block. The typical pumping direction is described in Fig. 8, line 1. The
typical pumping directions are not binding, and in some examples could
be inverted.
3.5 – SHAFT SEALING DEVICES
The impeller, i.e. the rotating mechanical part that allows the pump to
operate is activated through a shaft by the external motor; the pump body
has an opening for the shaft to pass through. The “shaft seal” is the device
that prevents liquid from leaking through the space between the shaft and
the opening in the pump body. Two types of seal are adopted:
-ring seal (lip seal) with stainless steel spring; the standard seal used in
brass versions is the NBR rubber lip seal, unless otherwise specified by a
label affixed to the pump;
-mechanical seal (Fig. 3A); the standard type of seal used in the
stainless steel series AL is the ceramic/graphite/ AISI 316/ NBR rubber
version, unless otherwise specified by a label affixed to the pump; it greatly
increases the number of hours for which the pump can operate before
requiring maintenance operations and does not cause wear on the shaft.
Various types of seals are available on request (Viton lip seal, silicon
carbide mechanical seals and/or parts in EPDM rubber, Viton, Teflon) to
adapt to the majority of requirements linked to temperature, corrosion and
abrasion. Should you require assistance, please contact our technical
department.
3.6 – OPTIONAL ACCESSORIES AVAILABLE
Handle and truck for easy transport.
Manual by-pass to adjust capacity and head; the relative instructions for
use are included in this manual.
Discharge plug or cock, to drain part of the pump body without removing
the hoses.
Filters, to prevent foreign bodies from entering.
Hose kit.
Hose fittings in nylon or stainless steel (for series AL pumps).
4 – INSTRUCTIONS FOR INSTALLATION AND USE
4.1 – HANDLING
Check the weight of the pump indicated on the ratings plate and adopt
methods in accordance with national safety regulations relative to manual
handling of loads. If necessary use lifting systems, lift trucks, personal
protection equipment for manual handling of loads and to prevent the
danger of crushed limbs. If the pump is to be moved frequently,
accessories (handle and truck) are available to facilitate handling.
Do not lift or transport the pump using the power cable, the hoses or
projecting parts (i.e. the inverter or terminal box). Lift the pump by
firmly holding the metal part.
4.2 – INSTALLATION AND USE
To install machinery supplied completed, strictly follow the
procedures indicated below. To incorporate partly completed
machinery, consider the following instructions within the limits of
their applicability. Use them to draw up instructions for use of the
final machinery. All mechanical and electrical installations to be
performed on unprotected parts must be carried out exclusively by
qualified technical personnel adopting personal protective
equipment to protect hands and limbs against crushing, to protect
from sprays and splashes of liquid and to protect against electrical
shock. These must be selected in relation to specific risk
assessment for the installation to be carried out.
Do not start the pump before having completed the installation.
4.2.1 – PRELIMINARY OPERATIONS
- Remove the pump from the packaging and check that all parts are intact:
any breakages that occur during transport can cause dangers of
mechanical or electrical nature.
- Assemble the handle (Fig. 5) or the truck (Fig. 6), if provided. During
transport, the pump must be disconnected from the power supply. After
transport, the truck must be positioned on a completely horizontal surface.
Check that accidental movements of the truck cannot cause danger.
- Position the pump in a dry place (the pump is not submersible) on a
horizontal surface; leave an empty space of at least 10 cm in front of the

motor cooling fan; secure the feet with bolts to prevent movement or falling
caused by vibrations during operation, to prevent people from tripping over
hoses or the power cable. Make the connections without damaging the
pump.
Never hang or fix the pump using the power cable.
- Fill the pump body with liquid to be pumped through one of the ports,
preventing the liquid from leaking out either through this port or the other
port; as the pump is self-priming, this operation is only necessary the first
time, or if the pump has been emptied; in fact, when it stops sufficient
liquid remains inside for subsequent priming.
Traces of lubricant (cutting fluids, greases) may be present on the inner
walls of the pumping body. If these substances can pollute the liquid to be
pumped (i.e. food substances), initial pumping must be performed
following the cleansing procedure described in Chapter 4.3.
Do not operate the pump dry.
4.2.2 – ASSEMBLING THE HOSES
- As shown in Fig. 5 or Fig. 6, screw the hose fittings to the ports; these
are provided standard with brass pumps, on request (in nylon or stainless
steel) for series AL pumps, after checking that the gaskets are present in
the fittings; the assembly shown is only indicative, the two fittings, straight
and curved, can be inverted.
- Provide a pair of hoses of suitable length and with the same internal
diameter as the external diameter of the fittings. The hose must be flexible
spiral, made of a material suitable for the type and temperature of the
liquid to be pumped, resistant to the internal vacuum and with a higher
operating pressure than the pressure generated by the pump (equal to
Hmax in Table A).
Insert the ends of the hoses into the hose fittings; secure the connection
using a hose clamp. It is not necessary to install a check valve; if the
liquid can contain hard suspended particles install a suitable filter in the
suction hose to retain them; the hose must not exert excessive forces on
the pump. Avoid excessive bending of the hoses to avoid kinks.
Insert the free end of the suction hose into the receptacle from which liquid
is to be drawn, at a depth at least twice the diameter of the hose and at the
same minimum distance from the bottom. Insert the free end of the
discharge hose into the receptacle to receive the liquid.
The discharge hose must be fixed, without compressing it,
to prevent extraction from the collection receptacle during
start-up or operation, which would wet and contaminate the
surrounding environment. In the event of use with dangerous
liquids, wear personal protective equipment selected according to
the specifications of the liquid, to prevent danger of contamination
or contact with exposed body parts.
4.2.3– ELECTRICALCONNECTION –GENERALINSTRUCTIONS
The inverter box (ref. 20) and the terminal box (ref. 21)
contain electrical parts; they must be disassembled
exclusively by a qualified technician, in compliance with
safety regulations.
Before making the electrical connections, check cables, plugs and sockets
for damage. Electrical connections must be protected against dampness
and sprays of liquid. Only use cables and components in conformity with
the safety provisions of Directive 2006/95/EC and suitable for the
current absorbed by the motor.
Pumps with three-phase and direct current motors are not provided with
overload protection; pumps with single-phase motors are provided with an
internal overload protection device and automatic reset only if the words
“Protetta da sovraccarico - Overload protected” appear on the yellow label

the necessary measures.
• Replace the terminal box and fasten it using the screws removed
previously.
4.2.4 – STARTING AND STOPPING
• Do not start the pump before having completed installation.
• Do not start the pump with wet hands or while standing on wet
surfaces.
• Under no circumstances insert fingers or other body parts or
objects through the ports: the pump contains moving parts.
Check that the hoses are positioned correctly. If the pump was supplied with a switch,
start it by switching this to the on position corresponding to the direction of pumping
required. If the pump was supplied with the terminal block, start it byconnecting it to
thepower supply.
In this phase, take great care that there are no leaks or
sprays of liquid from the installation. It these are present,
stop thepumpimmediatelyandtakeaction toeliminatethem.
The pump must not run with the hoses completely closed for
more than one minute.
After a short period required for priming, the pump will start to transfer
liquid.
If pumping is not obtained and the suction hose bubbles air into the liquid
to be sucked up this means that the pump is pumping in the opposite
direction: in this case stop the pump and reverse the pumping direction or
stop the pump and invert connection of the hoses to the ports.
Operation must always be supervised;
check that the following do not occur:
overheating of the motor surface, reduction
in speed or stopping, abnormal noises or other events that indicate
malfunctioning. In this case, stop the pump immediately, remove the
plug (where present) from the socket and consult Chapter 6.
The noise produced by brass pumps type 20, 25, 30, 35, 40 if they are run
when dry (to be avoided at all costs) does not indicate a fault, but is
caused by the fact that in these models the impeller slides on the shaft to
facilitate maintenance.
To stop the pump, position the switch to stop (0) or disconnect the power
supply.
After it is switched off, the pump remains filled with
liquid, which is essential for priming; if there is any
chance of the ambient temperature dropping to
below the freezing point of the liquid, empty the pump body to avoid
breakage.
4.3 – WASHING AND STORAGE
Before removing the hoses discharge any pressure present
inside the pump. If accessible surfaces are hot (see Chapter
5.2) wait for the pump to cool before handling it or use
appropriate gloves.
If the pump is used for dangerous substances, the user is
responsible for defining the procedures for handling, washing,
storing and disposal of waste fluids in compliance with the safety
regulations in force for the specific substances treated.
If the pumped liquid has no particular problems, (i.e. water, sea water or
soap), in the event of an extended period of disuse, wash the inner walls
of the pump by pumping clean water, empty completely, dry the outer
surfaces with a soft cloth, coil the electric cable and hoses and store in a
dry and protected area.
Cleansing procedure
This allows deeper cleaning than the procedure described previously and
can be used in many cases. In uses with foods it is performed during
installation and as part of the wash cycle.
• Prepare a detersive solution in a receptacle (i.e. common dishwashing
liquid diluted with clean hot water at 40-50°C).
• Insert the suction and discharge hoses of the pump into the receptacle
and recirculate the liquid for 5 minutes.
• Pump clean water until complete rinsing is obtained.
Use with slightly perishable food substances (vegetable oil, wine,
vinegar)
• Before and after use:
• Carry out the cleansing procedure;
• use the pump to recirculate a suitable sanitizing and disinfecting solution
(i.e. based on peracetic acid) for an adequate time;
• rinse the inside of the pump body by pumping clean water until the
sanitizing and disinfecting solution has been completely eliminated.
Before use, perform the start-up procedure, discarding a first fraction
of liquid. Dispose with the fluid used for washing and the discarded
liquid from start-up in compliance with the current provisions of law.
In the specific case of use with vegetable oils, if the pump is to remain
in disuse for a short period of time and subsequently used again for
the same type of oil, it can simply be emptied and the ports capped.
Use with highly perishable food substances (such as milk)
Wash before use, at each time interval established by the HACCP
protocol applied and after use, disassembling the pump, cleansing and
disinfecting its parts with methods depending on the type of liquid. This
operation must be carried out by qualified personnel experienced in
performing the pump disassembly and reassembly procedures.
4.4 – USE OF THE BY-PASS (optional device)
The by-pass is a device to adjust capacity and head of the pump and is
located on the outside in the form of a knob; it can be rotated counter-
clockwise to reduce the maximum capacity to around half and the
maximum head by around a quarter. During the priming stage close the by
-pass by rotating the knob completely clockwise, as priming capacity is
greatly reduced with the by-pass open.
4.5 - DEMOLITION
At the end of its useful life the pump must be demolished, in strict
compliance with the standards in force in the country of use. Do not
neglect any residue of liquid present inside the pump body.
Only EU countries
The pump belongs to the category of electric and electronic
equipment (EEE). The symbol shown here means that it cannot be
disposed of as domestic waste. At the end of its useful life the
owner must deliver the pump to a WEEE collection point, where it
will be subjected to recycling. For more information, contact the
relevant local authority department or the store from which the pump was
purchased.
5 – INFORMATION ON RESIDUAL RISKS
5.1 – CONTACT WITH MOVING PARTS
Do not insert objects through the holes in the fan cover (ref. 2), which
covers the motor cooling fan.
5.2 – TEMPERATURE OF ACCESSIBLE SURFACES
In typical conditions of use, the outer surfaces of the motor part
can reach temperatures in excess of around 40°C higher than the
surrounding ambient temperature. The outer surfaces of the
pumping body reach the temperature of the pumped liquid, and
can therefore be very hot or very cold. In the event of these temperatures
representing a danger, the user must adopt suitable protective measures
(enclose the pump with barriers, handle using suitable gloves).
5.3 –RISKSCAUSEDBYSPATTERINGANDLEAKAGEOFFLUIDS
Undesirable leakage or spraying of liquid may occur, for example,
in the following cases:
- installation procedure carried out incorrectly;
- wear and tear of hoses;
- wear and tear of sealing device (resulting in spattering of liquid from the
space between the flange and the pump body) or of other gaskets (O-ring
or counterflange gasket);
- corrosion of the pump body;
- incorrect reassembly after maintenance;
- pumping of cold liquids, with water vapour condensation forming on the
outer surface of the pumping body and consequent dripping.
These events cause a wet environment (with danger of electric shock,
danger of slipping, etc.) and the risk of persons, animals or objects being
struck by jets of liquid. In particular, maximum caution must be taken when
pumping liquids that are flammable, corrosive, at high temperature or in
WARNING
WARNING

42
any way dangerous for living things or for the environment. The user must
assess these risks and if necessary provide appropriate protection from
jets of liquid (i.e. screens) and collection vessels in a suitable position.
Liquid from leakages must be removed and disposed of correctly and
safely.
5.4 – RESIDUAL RISKS CAUSED BY FAULTY OPERATION
The pump is not provided with audible or visual alarms to indicate
breakages or malfunctioning. Therefore, the user must take suitable
measures to avoid damages (i.e. flooding) caused by failure or faulty
operation of the pump (i.e. installation of alarms, back-up pumps, etc.).

9 – NOTES FOR THE SERVICE TECHNICIAN
Chapter 9 and the relative subchapters contain information for
maintenance to be used exclusively by qualified technicians.
9.1 – DISASSEMBLING THE HYDRAULIC PART
Before disassembly and assembly operations, disconnect
the equipment from the power supply to prevent accidental
starting with moving parts exposed.
Internal parts can have sharp edges; therefore, they should be
handled with care wearing appropriate personal protective
equipment.
Before disassembly discharge any pressure present inside the
pump, wait for it to cool, empty it and dispose of the liquid contained
appropriately; if the pump is used for dangerous substances comply
with the safety regulations in force for handling of these substances.
The references below can be found in Figs. 1, 2, 3A, 3B, 4 and 9
according to the indications provided in paragraph 3.2.
- Unscrew the screws (ref. 30 or ref. 31) of the cover (ref. 11).
- Remove the cover.
- Remove the O-ring (ref. 12).
- Extract the impeller (ref. 13) as follows:
brass models type 20-25-30-35-40: the impeller slides on the shaft (ref.
64), it can be extracted simply using your fingers;
brass models type 50 and all stainless steel models: the impeller is
forced onto the shaft; to remove it use an extractor with appropriately
shaped claws (fig. 7); the hub of the impeller is provided with two
projections for this purpose (fig. 7); for stainless steel models type 20 use
the two projections present on the side of the pump body (fig. 7) for
extraction.
- Remove the tab (ref. 15).
- Extract the pump body (ref. 10) from the shaft.
- (Only for brass models type 20) extract the counterflange (ref. 5) from
the pump body and remove the gasket (ref. 8).

and alternately tightening opposite screws.
Models with forced impeller
The impeller is inserted using a hollow bar with internal diameter slightly
larger than that of the shaft.
- To prevent damaging the bearings, first remove the fan cover (ref. 2) and
place the back of the shaft (the end on which the motor fan ref. 1 is
mounted) on a soft metal surface.
- Striking the impeller (ref. 13) in a central position using the hollow bar and
a hammer, move it towards the wearing surface, leaving 0.1 mm
clearance.
- Fit the cover (ref. 11) and insert the screws (ref. 30 or ref. 31), gradually
and alternately tightening opposite screws.
- Strike the back of the shaft with a punch and hammer.
- Check that the impeller rotates freely rotating the motor fan (ref. 1) and fit
the fan cover (ref. 2).
9.2.1 – REPLACING THE LIP SEAL
(brass models type 20 and 50)
- Remove the worn lip seal (ref. 67) from its seat (located in the
counterflange ref. 5 for models type 20 and in the pump body for models
type 50) striking it using a solid drift of suitable dimensions as shown in
Fig. 23. (type 20) or Fig. 25 (type 50).
-Take an identical new lip seal and place it against the mouth of its seat as
shown in Fig. 24 (type 20) or Fig. 26 (type 50) facing in the correct
direction (the spring must be facing the inside of the pump).
- Insert the lip seal in its seat striking it using a solid drift with a slightly
smaller diameter to that of the outer diameter of the lip seal until it has

44
been completely inserted.
9.2.2 - REPLACING THE LIP SEAL
(brass models type 25-30-35-40)
The pump body is produced in two pieces: pump body (ref. 10) and rear
internal part (ref. 65), which is inserted into the pump body (Fig. 2 shows
the two parts disassembled, Fig. 10 after assembly). To replace the lip
seal (ref. 67) the rear internal part must be extracted from the pump body.
- Place the edge of the pump body on two surfaces made of soft material
(i.e. wood or aluminium) or any other material, provided that two pieces of
paper are placed between surface and body (Fig. 11).
- Take a solid drift (with diameter 28-29 mm and length greater than 60
mm) and strike the lip seal until it is extracted from its seat (Fig. 12).
- Place the lip seal against the edge of the rear internal part as shown in
Fig. 13 and strike it again with the solid drift and hammer; the internal part
will be removed together with the lip seal (Fig. 14).
- Place the pump body on a surface (Fig. 15); take an identical new lip seal
and place it against the mouth of its seat, facing in the correct direction
(the spring must be facing the inside of the pump).
- Insert the lip seal in its seat by striking it using a solid drift with a slightly
smaller diameter to that of the outer diameter of the lip seal until it has
been completely inserted (Figs. 16 and 17).
-Place the rear internal part against the body (Figs. 18 and 20) facing in
the correct direction (Fig. 19).
- Insert the internal part into the body using a solid drift of appropriate
dimensions (Figs. 21 and 22).
9.2.3 – REPLACING THE MECHANICAL SEAL
- Carry out the disassembly procedure without extracting the pump body;
for models type 20 also remove the body (ref. 10), extracting it from the
counterflange (ref. 5)
- Remove the fixing system of the rotating part of the mechanical seal (this
can belong to one of the types in Fig. 3B).
- Extract the rotating part of the seal (ref. 67A), the counterface (ref. 67B)
and the shroud (ref. 67C).
- Take an identical seal, separate shroud and counterface, clean the
lapped races of the rotating part and of the counterface with a soft cloth;
degrease the housing in the pump body and in the shaft, lubricate rubber
parts with soap and water.
-Insert the shroud into the seat in the pump body, followed by the
counterface.
- Insert the rotating part of the seal taking care that its rubber parts are not
damaged when passing over sharp parts.
- Remount the fixing system of the rotating part of the seal; for systems
provided with screws, clamp these so that the length of the rotating part is
between 13 and 14 mm.
9.3 – REPLACING THE BRUSHES
The two brushes (ref. 7) provided in direct current pumps are sliding
contacts subject to wear and must be replaced periodically; a brush is
completely worn when the brush spring is bottomed out; when the brushes
are worn operation first become irregular and then the pump stops; to
replace:
- remove the fan cover (ref. 2)
- unscrew the 2 screws on the brush holder (ref. 6) that connect the wires
of the 2 brushes to the motor winding;
- lift the springs that hold the brushes in place, extract them, replace them
and connect the wires using the 2 screws;
- remount the fan cover.
