OPERATING CYCLE
Due to limited weight and dimensions the pump does not require the use of any special
handling or lifting equipment. When handling manually, normal personal protective gear
should be worn (safety shoes with toe piece, etc.). The pump is carefully packed prior to
shipment. Upon receiving, the packaging should be inspected for damages and the pump
stored in a dry area at a temperature between -30°C /-22°F and 70°C/158°F.
It is recommended that the use of the pump be according to normative safety standards
and also as per the precautions listed below.
The pump can be mounted in any position. Fix the pump utilizing suitable diameter screws
corresponding to the holes.
Check that there has been no damage to the pump during transportation or storage. Both
inlet and outlet ports should be carefully cleaned removing possible dust or residual
packaging material. Verify that the available electrical power supply corresponds to the
specification requirements.
The pump can operate on a continuous cycle with the following conditions:
It is possible to operate at higher pressures/ampere draw if On/Off cycles are used. This will
allow the motor to cool down to the indicated temperatures.
Long pipelines and / or reduced diameters, bottlenecks and dispensing guns, affect the
operating pressure (which is not automatically limited): in these cases, check that the
pressure and the electrical draw do not exceed the values of the attached diagrams.
Ø
Ø
pressures not exceeding 50% of the maximum pressure indicated in the technical
data
temperature of the motor below 60/70 °C - 140/158 °F
WARNING: the above indicated temperature ranges are applicable to all components
of the pump and these limits must be respected in order to avoid any possible damage
or malfunctioning.

To ensure the correct directional flow of the fluid as indicated by the arrow on the top plate, it is
necessary to connect the positive pole (+) of the battery supply to the red wire on the motor
end-cap and the negative pole (-) to the black wire. Electrical connections must be made
using adequate terminal blocks and connectors ensuring a tight fitment of the electrical
cables. Bad wiring can cause power losses and/or overheating of the cabling itself.
Ø
Ø
Ø
Prior to making any tube/hose connections, check that the inlet ports have no end
caps;
Do not position the pump at a excessive height with respect to the minimum level of
the fluid to be transferred. Damage may occur if this height is exceeded as the pump
may not draw fluid. Make sure that the outlet tube is empty and without chokes;
Avoid choking the inlet or outlet tubes so that efficiency is optimized.
The use of an inlet filter is recommended especially with fluids containing impurities
(mesh ASTM no. 35).
Utilize tubes and connection pieces that are resistant to the fluid types handled and
avoid any possible environmental dispersion.
Ø
Ø
In this case frequent cleaning and maintenance of the filter is
advisable. The standard filter withstands a maximum positive pressure of 0.5 bar.
The electrical installation of the pump must include a protection fuse which is suitably rated
as indicated on the motor label.
Always mount the anti vibration rubber fittings supplied with the pump kit. Their usage
ensures a consistent reduction in noise and vibration levels. Electrical cabling size should
depend on the distance between pump and battery/power supply (see Tab.1 EN). The use of
undersized cabling can cause overheating of the electrical wiring and subsequent fire
hazard. There will also be a voltage drop at the motor terminals with a consequent reduction
in efficiency. The flow rate value indicated on the motor label is obtained with internal tube
diameter indicated on Tab.1 EN. Tubes with inferior diameters will cause an increase in
current with potential risk of motor overheating.
WARRANTY EXPIRES IF NO FUSE IS UTILIZED
WARNING: it is the responsibility of the installation technician to ensure a correctly
designed circuit installation fitted according to regulations. Environmental risks must
be taken into account with the installation.
WARNING: DUE TO THE EMI FILTER THE PUMP IS NOT SUITABLE FOR
SWITCHING APPLICATIONS (PWM DRIVER)

GOOD PRACTICES ENSURING A WELL FUNCTIONING PUMP

Check the effectiveness of the battery power supply (voltage activity);
Check if the fuse has blown;
Check for any foreign matter present in the pump body. To do this, disconnect the
power supply and unscrew the four fixing screws, remove the front cover plate and
inspect the chamber. Replace the cover plate in the same initial position after
inspection;
Avoid running the pump dry for more than a few minutes. Pumps found defective
that have run dry in the absence of fluid are not covered by warranty;
The average life span of the motor commutator brushes is approximately 2500
hours under normal operating conditions. Stoppages are possible due to brush
wear and tear after such a time period.

The pump is fitted at an excessive height above the fluid level
The pump has run dry for too long a period
Long periods of inactivity. In this case it is advisable to add liquid directly into the
chamber before start-up
Air leak at the suction pipe due to the following reasons, possible cuts in the pipe,
inadequate hose clamps, malfunctioning of the filter due to defective/worn seals or
filter clogged
Air leak at the front plate cover due to the following reasons, loose fixing screws,
poor effectiveness of the seal
Faulty electrical cable connections
Presence of obstructions or restrictions in the suction or delivery pipes or the use of
special devices (eg. automatic spray pistol or Aquastop)
Presence of liquid loops in the outlet tube
ØDirty bypass valve (VP45 series)
If it is expected that the pump will not be used for a period of at least 30 days, especially in the
case of usage with water, it is advisable to run fresh water through it and to then loosen the
front plate screws. Upon re-use, run the pump briefly (a few seconds) and tighten the screws
again. Check under conditions of maximum operating pressure that the motor current value
is within the motor label specifications.
