HC150 / HC101
Solenoid driven dosing pump
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.
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.

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.
