The first letters of the pump model initials make it possible to identify the specific model (LW,
FW, ZW, HW, TW, SW, AX); the third letter allows you to determine the maximum rotation speed
according to the following table:
THIRD LETTER
N
RPM
1000
Assente 1450
S 1750
R 2800
D 3400

27
For instance: TWN 5636 (1000 RPM), LW 2020 (1450 RPM), HWD 4040 (3400 RPM).
The presence of letter K, preceded by a hyphen, means that the pump (LW-K, ZW-K) is equipped
with an already built-in pressure limiting/adjusting valve (for instance: LWR-K 2020, ZW-K
4022): This rule cannot be applied to the AX models, because they are all already equipped with
a built-in pressure limiting/adjusting valve.
The numbers of the model initials make it possible to determine the maximum flow rate and
pressure.
With the first two figures (if the number is made up of four figures) or with the first three figures
(if the number if made up of five figures) you can establish the maximum flow rate according to
the following table:
Maximum flow rate in l/min. = first two (or three) figures x 0,378
Maximum flow rate in US gpm = first two (or three) figures : 10
For instance: TW 10522 (105 x 0.378 = 39.7 l/min.), LW 2015 (20:10 = 2 US gpm).
With the last two figures you can determine the maximum pressure according to the following
table:
Maximum pressure in bar= last two figures x 6,9
Maximum pressure in psi=last two figures x 100
For instance: TW 10522 (22 x 6.9 = 151.8 bar), LW 2015 (15x100 = 1500 psi).

2.2 SAFETY DEVICES
DCAUTION
vThe machine with the built-in pump must be always equipped with a pressure limiting/adjusting
valve.
vIf the machine with the built-in pump is equipped with a safety valve, in case it is activated
very often, immediately interrupt the use of the machine with the built-in pump and have it
checked by a Specialised Engineer.

28
Pressure limiting/adjusting valve
Mounted as standard on LW-K, ZW-K, AX and available as optional accessory for the other
models.
It is a valve that makes it possible to adjust the working pressure and that allows the pump fluid
to reflow towards the by-pass duct, thus avoiding the onset of dangerous pressures, when you
interrupt the flow rate or when you try to set pressure values above the maximum allowed ones.
DCAUTION
vThe pressure limiting/adjusting valve is calibrated by the Producer or Builder of the machine
with the built-in pump. Never operate on the pressure limiting/adjusting valve not to alter
the calibration: operate on it only by using the knob (15).
2.3 IDENTIFICATION PLATE
DCAUTION
vIf during the use the identification plate is worn, apply to the dealer or to an authorised
service centre to reset it.
The identification plate (7) contains the serial number and the pump model with a suitable code
hinting to the main technical features of the pump (see also the paragraph “FEATURES AND
TECHNICAL DATA”).
3. INTENDED USE
DCAUTION
vThe pump is only intended for pumping:
- high-pressure water in washing machines (water cleaners);
- water not for food use.
vThe pump is not intended for distributing:

WARNING
vIn case of use at very low temperatures, make sure that there is no ice inside the pump.
vCarry out the scheduled checks of the ordinary maintenance with special reference to the ones
relating to oil.
b) Replace the oil plug without vent (17) with the oil plug with vent (8). This operation could
have already been carried out by the Producer of the machine with the built-in pump.
c) With pump at a standstill, check that the oil level corresponds to the middle of the oil level
light (10). The oil level can be also checked (apart from the AX models) by unscrewing the
plug with vent (8): the correct level must be included between the two notches on the rod.
Remember that the oil level must be always checked with pump at a standstill and completely
cooled down.
For possible filling, refer to the types of lubricants reported in the paragraph “FEATURES
AND TECHNICAL DATA”.
d) By referring to the use and maintenance manual of the machine with the built-in pump, check
the cleaning of the suction filter.

4.2 STANDARD OPERATION (HIGH PRESSURE)
DCAUTION
vUsing the pump requires care and attention. Never entrust it to others without ascertaining
under your own responsibility that they have read the manuals and know how to use the pump.
The pump must not be used by children or not trained personnel.
vObserve the safety instructions contained in the use and maintenance manual of the machine
with the built-in pump with special attention to the possible use of individual protection
devices (safety goggles, hear muffs, masks, etc.).
vObserve the safety instructions contained in the use and maintenance manual of the possible
optional accessories that are used.
vCarry out the operations concerning commissioning recommended by the producer of the
machine with the built-in pump.
vSpecial attention must be paid to the use of the pump in rooms where there are moving vehicles
that can squash or possibly damage: delivery pipe, water gun and lance.
vDuring the operation, always keep checked the pump and aloof from children’s reach. Pay
special attention to the use of the pumps in nurseries and hospitals because in these places
there can be children, elders or disabled people without aid.
vBefore starting the pump, wear clothes that guarantee a suitable protection from wrong
manoeuvres with the water jet under pressure. Do not use the pump near persons if they do
not use protective cloths.
vThe high-pressure jets can be dangerous if they are not used correctly. Do not direct the jet
towards persons, animals, electrical devices under voltage or towards the pump itself.
vDuring the use, firmly grasp the possible water gun, because when you activate the lever you
undergo the reaction force of the high-pressure jet.
vDo not direct the high-pressure jet against yourself or other persons to clean cloths or
shoes.
vDo not direct the high-pressure jet towards materials containing asbestos or other substances
which are damaging for the health.
vPay special care to what is described in the paragraph «OPERATION WITH
DETERGENT».
vThe machine operation in closed rooms is forbidden if the built-in pump is activated by an
explosion engine.
vDo not approach the pump moving parts, even if they are suitable protected.

31
vDo not remove the protections of the moving parts.
vDo not operate on pipes containing fluids under pressure.
vDo not carry out maintenance on the pump if it is working.
vObserve the instruction of chapter “INTENDED USE”.
vDo not change in any way the pump installation conditions and in particular do not change
its fixing and hydraulic connections.
vDo not deactivate or tamper with the controls, the safety devices and the pressure limiting/
adjusting valve.
vThe working pressure must never overcome the maximum value that is intended for the pump
(see also the paragraph “TECHNICAL FEATURES”.
vThe connection to the mains of the machine with the built-in pump must be carried out by a
Skilled Engineer according to the standard which are valid in the relevant country.
To carry out correctly what described below, refer also to the use and maintenance manual
of the machine with the built-in pump.
a) Set the delivery pressure to zero, by keeping the delivery circuit opened. In case of a water
cleaner, for instance, you just need to press the lever of the water gun.
b) Operate the pump to allow its priming.
c) If there is the possibility to adjust the delivery pressure, set the wished value. In the LW-
K, ZW-K and AX models, the pressure adjustment can be obtained by operating on the
knob (15): by rotating it in clockwise direction the pressure increases and by rotating it in
counter-clockwise direction it decreases.
DCAUTION
vNever operate on the pressure limiting/adjusting valve not to alter the calibration: operate
on it only by using the knob (15).
DCAUTION
vTo allow a fast pump priming, operate as per point a) each time the pump is emptied from the
fluid.
vIn the models LW-K, ZW-K and AX and in all those applications where the by-pass of the
pressure limiting/adjusting valve is connected to the pump suction, do not keep the flow rate
side closed for more than five minutes in order to avoid that the water recirculating in the
pump head overheats with the subsequent gasket damaging.
4.3 OPERATION WITH DETERGENT
DCAUTION
vUse only the detergents recommended by the Producer of the machine with the built-in
pump.
In particular, never suck fluids containing solvents, petrol, thinners, acetone and combustible
oil, because the sprayed product is highly flammable, explosive and toxic.
vCarefully read all the prescriptions and warnings on the label of the detergents supplied with
the pump in order to take the suitable measure not to generate dangers for you and for the
environment.
vPreserve the detergents in a safe place that cannot be reached by children.
In case of contact with the eyes, was immediately with water and apply to a doctor by
bringing with you the detergent package.

32
In case of ingestion, do not induce vomiting and immediately apply to a doctor by bringing
with you the detergent package.
The possibility to suck detergent is intended as standard only for the models LW-K, ZW-K and
AX.
For the detergent use modes, refer to the instructions on the label on the detergent package by
observing the doses.
To carry out correctly what described below, refer also to the use and maintenance manual
of the machine with the built-in pump.
a) Set the pump pressure below 30 bar/435 psi (for instance, in case of a water cleaner, this
can be obtained by activating the low-pressure operation on a lance with the suitable nozzle
holder).
b) If there is the possibility to adjust the detergent suction, operate on the knob (16): by screwing
it you decrease the delivery of the sucked detergent and by unscrewing it you increase it.
WARNING
vTo avoid fouling and/or deposits, after the detergent use it is a good habit to wash the passage
ducts by sucking some water.
5. STOPPING
DCAUTION
vCarry out the operations relating to stopping recommended by the producer of the machine
with the built-in pump.
No part of the pump must be moving and no pipe must have fluid under pressure.
a) Stop the pump and close the water supply.

In case of very low temperatures, in order to avoid the formation of ice inside the pump, it is
possible to activate, before activating the «STOPPING» procedure, to suck an anti-frost product
for cars after referring to a Specialised Engineer, because the fluid could damage the gaskets
and afterwards to empty it completely.
In case of very low temperatures, if it was not possible to protect the pump as described above,
before restarting it, bring it in a warm environment for a short time that is enough to melt the
possible ice inside it.
The lacked observance of these simples prescriptions can bring about a serious pump
damage.
DCAUTION
vThe anti-frost liquid must be duly disposed of and not dispersed in the environment.
NOTE
After a long pause of use, a slight water dripping under the pump can take place. This dropping
disappears normally after some working hours. If it persists, apply to a Specialised Engineer.
6.2 ORDINARY MAINTENANCE
