Dear Customer, thank you for choosing a MOULDPRO descaling pump.
MANUAL
This manual is a safe guide for the use of the pump. Please read it carefully in all its parts
before use.
This manual contains important information for the proper working and use of the
equipment.
MOULDPRO reserve the right to introduce anyfuture changes without notice or
replacement.
PRELIMINARY INSPECTION
Upon receipt of the pump, take it out from the carton and check it is in perfect
condition.
Also check that the data on the rating plate correspond to required ones
(please see section 3 “Technical Features”). For any problem, immediately
contact the supplier specifying the kind of fault.
In case of doubt about the safety of the machine, do not use it.
DESCRIPTION
Vertical axis pumps with tank for descaling heat exchangers, pipes, coils and any similar
scaled situation. Pumps are supplied ready to use, in strong carton boxes with related
user’s manual.

2- THE ADVANTAGES OF THE PUMPS WITH FLOW REVERSER
Time and, above all, temperature increase make
calcium salts, usually present in water, precipitate
in the form of microcrystals and settle on metallic
surfaces of pipes, plant coils and heat exchangers,
thus reducing flow rate and thermal efficiency.
To restore the original plant performance it is
necessary to carry out a descaling with specific
products and equipment.
The flow reverser device attacks scale on both
sides, thus making descaling particularly fast (as
the normal dissolving action is combined with the
detachment in flakes of the scale, made friable
from the double attack) and effective, even when
pipes and exchangers are almost totally clogged.

5- USE
5.1- How to prepare the pump and check the seal
- Fill the tank with enough water to ensure that the pump
rotor housing is submerged during operation.
- Screw the outer ends of the flexible hoses securely to the
exchanger to be descaled.
- Connect the power cable to a single-phase 230 V power
supply.
- Switch on the pump and check the seal of the hose fittings
on the exchanger and on the pump. In case of leaks of
liquid, check hoses and fittings and replace the defective
components, if necessary.
- When seal is safe, switch off the pump.
- If necessary, add more acid by referring to the dilution
specified in the data sheet of the product.
5.2–Descaling
- Switch on the pump.
IMPORTANT: During use, the tank cap should remain open to allow for the
passage and elimination of the gas evolved during descaling. Check that the foam
level does not exceed the maximum filling level.
- Periodically move the handle of the flow reverser from one stop to the other. By
attacking scale from both sides it is possible to clean piping which is almost totally
obstructed and descaling time is considerably reduced.
- Scale removal can be considered complete when bubbles no longer form in the
return pipe and the solution is still acidic.
For enquiries on spare parts, please specify serial number of pump (shown on
product and carton).

User Guidelines –DP15M, DP30M Ver01
5.3–How to clean the pump
- After descaling REMOVE THE DESCALING LIQUID FROM THE TANK and wash
out the pump by circulating clean water through it for at least 10 minutes.
PRECAUTIONS
Only use MOULDPRO chemicals in order to ensure good working and avoid
damaging the equipment.
Once the lifetime of the pump has expired, do not dispose of it
with household waste. The pump must be recycled in authorized
centers and can be assimilated to a household appliance.
During handling lift the pump and do not drag it in order to avoid damages to
the tank. Temperature of the descaling solution must never exceed 50 °C.
Flexible hoses and fittings can be damaged in time; make sure to check the
seal whenever using the pump, as indicated in the pump preparation
instructions.

User Guidelines –DP15M, DP30M Ver01
6 - SAFETY INSTRUCTIONS
Before installing the motor pump, make sure the power supply is fitted with
grounding and complies with the regulations.
- Avoid using the pump in places where there are liquids, gases, flammable powders
or risk of explosion.
- Before plugging in the pump to the outlet, make sure the switch is off.
- The outlet must be suitable for the plug of the pump. Do not use non CE-marked
defective outlets.
- Use (CE) approved extensions, only if necessary.
- Do not use plug adapter. Do not carry out any modifications to the plug nor to the
electrical cable.
- Pump shall always kept in perfect efficiency.
- During maintenance operations, check the switch is off and the plug is not
connected.
- All maintenance operations must be carried out by the authorized Technical
Assistance Service.
- Only use MOULDPRO original spare parts.
- Do not carry out any modifications to the pump if not authorized by MOULDPRO
Technical Department (ask for written authorization).
- The warranty is not valid if the pump is repaired by personnel not authorized by the
manufacturer, that also means operating with unsafe and potentially dangerous
equipment.
- Keep children and unauthorized persons away from the pump.
- Keep the pump out of reach of children and unauthorized persons.
- Do not use the pump if tired or under the effect of alcohol, medicines or drugs, do
not eat or smoke.
- When using the pump, wear overalls, do not wear jewelry, and keep hair away from
the pump.
- When handling descaling liquids, be very careful. It is necessary to use Individual
Protection Equipment (IPE).
