1 INTRODUCTION
Thank you for having purchased an Aqua product.
The HC150 / HC101 series solenoid driven dosing pumps represent the ideal solution
for dosing small amounts of chemical products.
The pumps are regulated through analogue controls, including a two-colour LED and a
regulating knob.
The HC101 model has also a mechanical stroke length facility included in addition to
the on/off switch and electronic stroke frequency control function. The operator may
now make an extra manual mechanical stroke length adjustment to the dosing pump,
thus further increasing the pumps accuracy, and greatly increasing the "turn down
ratio" to achieve much lower dosing rates. The stroke length adjustment should only be
made when the pump is running, and is achieved by pushing and turning the knob.
There are 20 settings available between 0% and 100%.
NB. Below 10% the adjustment will not be linear.
The figure shows the large adjustment knob of the mechanical stroke length, in a central position:

There are 2 protection devices inside the pump: a varistor and a fuse.
If it is necessary to remove the pump from the system, it is essential that the rubber
discs are put back in so as to avoid liquid leaking out from the pump head.
During the installation phase make sure that the delivery tube is attached correctly, to
avoid it being subject to wear when rubbing against rigid bodies. Also avoid
unnecessary curves in both suction and delivery.
The connection from the pump to the system must be made always and in any case
using the injection valve (1/2” Gm) provided with the installation kit.
The PVC Crystal tube (soft) is only connected in suction (on the foot strainer side). On
the other hand, the polyethylene tube needs to be attached to delivery making sure that
the cut of the tube is clean and has not caused lateral crushing; it is advisable to use a
utility knife rather than scissors.
All operations must be carried out wearing suitable gloves and eyewear for the product
being used, consult the supplier of the chemical product accordingly
1.2 Models
The HC150 / HC101 series are composed of three models:
HC150 / HC101 costant
A constant dosing pump, with the possibility of regulating the flow between 0 and 100% of the nominal flow.
Using the regulating knob it is possible to set the dosage frequency and therefore the flow. The pump is
equipped with two regulating scales so that you always have an exact dosage for any requirement: 0…100%
and 0…20%.
HC150 / HC101 mA
The pump can operate in constant mode or in proportional current mode (mA).
In constant mode it operates like model HC150 costant, whereas in proportional mode mA, the number of
impulses is proportional to the current signal connected to the BNC - red connector.
HC150 / HC101 PI
The pump can operate in constant mode as well as proportional mode to pulses sent from a counter.
In constant mode it operates like model HC150 costant whereas in proportional pulse mode the pump
provides an injection for each “N” of pulses that the pump receives on the BNC – red connector, or N
injections for each pulse.
It is possible to set the "N" value between 1 and 1000 in division, or between 1 and 10 in moltiplication;
setting the "N" value has been made easier as the interval has been divided into 11 sub-intervals so that you
always have the same resolution on the regulating knob.
1.3 Available flows
For each series it is possible to have several models depending on the performance you wish to obtain:

ADSP9500090 Rev. 3.1 del 05/10/2020 7
2.0 INSTALLATION AND TECHNICAL FEATURES
2.1 General regulations
Pump installation must be carried out as follows:
On a horizontal support (ex.: storage tank) or on the wall-mount bracket (optional) as long as the pumps
remains in a vertical position +/- 15°.
Away from sources of heat in dry locations, at a maximum temperature of 45° C, and a minimum of 0° C.
In a ventilated environment and easily accessible to an operator for periodic maintenance.
Above the level of the liquid to be dosed, at a maximum height of 1.5 metres, nevertheless bearing in mind
that if the requirements of the system envision the need to position the pump below the level of the liquid
(positive suction head), in order to avoid problems with the siphon, always use the injection valve or a
counter pressure valve.
Do not install the pump above the tank when using liquids that emit fumes, unless it is sealed shut.
2.2 Accessories included

2.4 Hydraulic connection
After having positioned the pump correctly (see general regulations) proceed with making the connections.
Suction: Connect the suction tube (soft PVC Crystal) to the foot strainer included by inserting it into the hose
connection, secure the tube by tightening the ring nut. When using the low level probe, it must be connected to the
filter using the bracket provided. Position the foot strainer inside the liquid draught tank. Connect the other end to
the pump suction (lower part of the pump head), unscrew the ring-nut from the fitting, remove the adapter, the pipe
support and the white rubber disc. Slot the tube through the ring nut, then through the adapter, insert the tube into
the 4x6 pipe support. Screw the ring nut onto the pump head, lock it all together by tightening the ring nuts all the
way. See figure 3.
Delivery: The connection from the pump to the system must be made always and in any case using the injection
valve (1/2” Gm) provided with the installation kit. After having applied a 1/2" Gf fitting to the duct of the system to be
treated, seal the injection valve with teflon and insert it into the tube at the point where the product will be injected.
Unscrew the ring nut, insert the delivery tube as far as it will go (rigid polyethylene) onto the hose connection of the
valve fitting, lock it all together by tightening the valve. Connect the other end to the pump delivery (top part of the
pump head) repeating the operation as described above. See figure 3.
Purge: Connect one end of the tube for manual purge (PVC crystal) to the hose connection located on the bottom
right of the pump head, while the other end goes inside the liquid draught tank. See figure 4.
INSTRUCTIONS FOR PRIMING
To prime the pump in case of excessive counter-pressure in delivery, turn the knob located on the top right of the
pump head by a quarter or half rotation as shown in figure 4 until the pump head itself is completely full.
Screw the knob back on and tighten it.
2.5 Principle of operation
The operation of the dosing pump is guaranteed by a teflon membrane mounted on the piston that is driven by an
electromagnet that receives pulses in direct current from an electric circuit.
The movement of the piston produces pressure on the membrane, by effect of a counter opening and closing of the
suction and delivery valve the liquid found inside is expelled.
At the end of each pulse the spring, with the opposite effect of the magnet, brings the piston back to the initial
position, drawing liquid in through the suction valve.
The materials used to build it also make it suitable for particularly aggressive liquids. In any case we advise you to
consult the various compatibility tables or our technical office.

3 PROGRAMMING THE PUMPS
3.1 HC150 / HC101 costant
Programming the HC150 / HC101 costant pump or in constant mode is based on the setting, using the knob,
regulating the number of pulses per minute that the pump must carry out.
It is possible to regulate the number of pulses per minute, and therefore the flow of the pump, using two regulating
scales:
Full: 0…100%
Reduced: 0…20%.
3.1.1 Scale change procedure
The following procedure allows you to switch from one scale to the other.
To perform this operation it is advisable to use a medium flat-tip screwdriver.
Turn the regulating knob to the minimum 0% (fully rotated counter clockwise):
The frequency of the flashing LED (green) indicates the scale that is currently in use:
quick flashing: 0…100% slow flashing: 0…20%.
Turn the regulating knob to the maximum position (fully rotated clockwise) immediately followed by (within
2 seconds) bringing the timer back to the minimum position.
2 seconds
The frequency of the flashing LED has now been changed to indicate the change in regulating scale,
repeat again if necessary.

3.2 HC150 / HC101 mA
The pump can operate in constant mode or in proportional current mode (mA).
In constant mode it operates like model HC150 costant, whereas in proportional mode mA, the number of impulses
is proportional to the current signal connected to the BNC - red connector.
Using the regulating knob it is possible to set the maximum flow of the pump associated to the maximum input
current value, i.e. 20 mA.
After which the pump will dose proportionally between 4 and 20 mA, as shown in the graph provided below:
In proportional current mode it is also possible to use one of the two pump operating scales, as in the constant
version.
The HC150 mA pumps can be piloted, for proportional dosing, from any regulating instrument that is capable of
providing a current signal between 4-20mA (ex.: pH-metres, redox meters, residual chlorine meters, conductivity
meters etc.)
This signal must be applied to a cable with a BNC - red pump connector, being careful of the polarity:
Centre wire: positive.
Sheath: negative.
3.2.1 Meaning of two-colour LED
The colour of the LED immediately indicates the type of proportional pump operation, in fact:
Green LED: the HC150 mA pump is in constant mode
Orange LED: the HC150 mA pump is in proportional mode

3.3 HC150 / HC101 PI
The pump can operate in constant mode as well as proportional mode to pulses sent from a counter.
In constant mode it operates like model HC150 / HC101 costant whereas in proportional pulse mode the pump
provides an injection for each “N” of pulses that the pump receives on the BNC –red connector, or N injections for
each pulse.
It is not designed to memorise the input pulses in case the frequency exceeds the maximum frequency of pump
operation.
The "N" parameter can be set between 1 and 1000 in division, or between 1 and 10 in moltiplication, in fact it is
possible to select 11 interval scales and then using the regulating knob select the desired value.
The selectable scale intervals are:
When setting the "N" parameter remember that in division when the knob is at its maximum it
corresponds to the lowest N value of the selected interval.
3.3.1 Interval scale change procedure
The following procedure allows you to switch from one interval scale to the other.
To perform this operation it is advisable to use a medium flat-tip screwdriver.
Turn the regulating knob to the minimum 0% (fully rotated counter clockwise):
The number of flashes of the LED (orange in division, green in moltiplication) indicates the scale that is
currently in use:
This is a circular menu, therefore if it exceeds the desired interval, it is not possible to go back, but
you must repeat the procedure three times until you reach the required interval again.
Turn the regulating knob to the maximum position (fully rotated clockwise) immediately followed by (within
two seconds) bringing the timer back to the minimum position.

3.3.4 How to choose the pump
As the number of m3of water to be treated in the system is known, and the quantity of product to be dosed,
expressed in P.P.M. (parts per million) it is possible to define theminimum hourly capacity of the dosing pump
required, using the following formula:
L/H flow of the HC150 PI pump.
PPM quantity of product to dose (gr/m3).
K concentration of the chemical product to dose (pure product K=1).
Example: Sodium hypochlorite at 12%; K = 100:12 = 8.3.
m3maximum flow of the water to be treated expressed in m3 / H.
3.3.5 How to set the “N” parameter in 1/N mode
To identify the value of N (position of the knob) proceed as follows:
N number to set on the HC150 PI pump.
pul/L pulses per litre provided by the counter.
cc quantity of product dosed per single injection (expressed in cc) of the pump.
PPM quantity of product to dose (gr/m3).
K concentration of the chemical product to dose (pure product K=1).
If in the calculation the "N" parameter is:
N<1 (N less than 1) it is necessary to install a counter with a number higher than the number of pulses per
litre or a pump with a greater capacity per injection.
N>1000 (N greater thasn1000) it is necessary to install a pump with a lower capacity per injection.
When setting the "N" parameter remember that when the knob is at its maximum it corresponds to
the lowest N value of the selected interval.

4 MAINTENANCE
4.1 General regulations
Periodic maintenance is of fundamental importance to keep the pump in good running order and make it
last over time.
The tips provided below must be followed systematically and to the letter. It is extremely difficult to define
the standard times required for maintenance beforehand, as the factors that determine the wear of the
pump, and in particular the parts that are in contact with the liquid, are numerous.
This also applies to the type of product used to clean the materials that are in contact with it (valves, etc.)
as it depends on its compatibility with the chemical product being dosed. Having said this, we can take as
an example a product, such as sodium hypochlorite, that develops crystals, which is often used with our
pumps, and with which we have a great deal of experience, and trace an identity kit of the type of
maintenance required.
4.2 Periodic maintenance
The level of the liquid to dose on the system must be checked very often, so as to avoid the pump from
working on empty.
The pump materials that are in contact with the chemical product are: pump head, foot strainer and
injection valve must be checked and cleaned at least every three months. If the products are particularly
aggressive increase the frequency of cleaning.
If the pump is left unused for a prolonged period the product may form build up that can cause malfunctions
the next time it is started up. We therefore recommend always cleaning the valves thoroughly (wash under
running water) every time the pump is started after prolonged periods of inactivity. Alternatively, it is
possible to wash the pump beforehand by running it for at least 30 minutes with the foot strainer immersed
in water, before leaving the pump to rest for a long period of time.
4.3 How to intervene
Before performing any type of intervention consult the safety technical data sheets of the chemical product to be
dosed and proceed as follows:
1. Turn off the pump
2. immerse the foot strainer and the delivery tube in clean water and run the pump for a few minutes to make
water flow through the pump head.
If there are any crystal formations requiring removal proceed as follows:
1. Immerse the filter and the delivery tube in a solution that can remove the crystal formations (for example,
hydrochloric acid for sodium hypochlorite crystals).
2. Run the pump for a few minutes to allow the product to carry out a deep cleaning action.
3. Once this action has been completed, repeat it using water and connect the pump to the system.
.
4.4 How to change parts after normal wear
Changing fuses (model 5x20 –1.6 A –Delayed)
Proceed as follows:
1. (Where included) Position the stroke regulating knob to minimum.
2. Unscrew the screws for the frame.
3. Open the front and rear part being careful of the knob's return spring (where included)
4. Change the fuse which is clearly visible on the circuit.
5. Reassemble everything being careful that the regulating knob (where included) is always at minimum and
that the spring is inside it.
Cleaning the valves
Proceed as follows:
1. With a small implement lever the groove on the thread of the pump head.
2. Pull out the valve cartridge being careful not to remove or damage the O-rings.
3. Wash the valve cartridge under running water.
4. To wash the valve thoroughly, dis-assemble the valve cartridge, being careful not to lose the parts that it is
composed of.
5. Re-assemble the valve following the order of assembly indicted in the exploded view in figure 7.

6. Re-insert the cartridge into the pump head.
Changing sealing O-rings and the diaphragm
Proceed as follows:
1. Remove the small round cover from the pump head using a small utensil to lever it off.
2. Unscrew the 4 screws on the pump head with a Ø 4mm hex key.
3. Remove the pump head being very careful that it does not contain any liquid.
4. Remove the old 3143 O-ring with a screwdriver and insert the new one.
5. Unscrew the diaphragm by hand (if necessary use a pliers wrench), then screw on the new diaphragm after
having added a small amount of Loctite® 222 to the thread of the diaphragm.
6. Position the pump head and screw on the 4 screws by cross-tightening them for a perfect seal. To avoid
the screws from accidentally loosening we recommend using a drop of Loctite® 222 on the thread of each
screw.
4.5 Troubleshooting
Problem: the pump does not turn on and the LED stays off
Solution:
1. Make sure the connection to the electrical network has been set up correctly in accordance with the
information provided on the pump's identification plate.
2. Check the integrity of the fuse.
3. Change the electronic board.
Problem: the pump turns on but does not beat
Solution for all models in constant mode:
1. Make sure the knob is not at 0%.
2. Make sure the pump is not in temperature alarm or level alarm.
Solution for all PI models in proportional mode:
1. Make sure the connection between contactor and pump is set up correctly.
2. Make sure the contactor emits pulses.
3. Make sure the pump is in perfect running order, following the procedure below:
Select the interval scale 1…100
Set the regulating knob to max (fully rotate clockwise):
Disconnect the contactor connector from the pump (BNC - red)
Using pliers try to touch the centre of the BNC with the outer edge
The pump should emit a beat, if it does not do so, change the electronic board.
Solution for all mA models in proportional mode:
1. Make sure the connection between instrument and pump is set up correctly.
2. Using a digital multi-meter make sure the instrument is providing the correct current.
Problem: the pump is working correctly but does not inject liquid into the system
Solution:
1. Check the level of product in the tank.
2. Make sure the foot strainer is not clogged up.
3. Make sure that the injection valve is not clogged up.
4. Carry out a maintenance operation on the suction/delivery valves. If evident malformations arise make sure
that the material is compatible with the product being dosed by consulting the chemical compatibility table,
and then go ahead with changing it.
Problem: liquid leaking from the pump head
Solution:
1. Make sure the delivery tube is inserted well and that the ring nut is tight.
2. Check the O-rings on the fittings.
3. Dis-assemble the pump head and check whether the sealing O-ring of the membrane is intact.
