2.0 - DLX-MF/M AND DLXB-MF/M MICROCONTROLLER DOSING PUMPS
Multifunctions dosing pumps with a microprocessor and a liquid cristal display allows a accurate injection puls-
es choice.
2.1 - OPERATION
The metering pump is activated by a teflon diaphragm mounted on a piston of an electromagnet.
When the piston of the electromagnet is attracted, a pressure is produced in the pump body with an expulsion
of liquid from the discharge valve. Once the electric impulse is finished a spring brings the piston back to the
initial position, with a recall of liquid through the suction valve.
The operation is simple the pump does not need lubrication, therefore maintenance is reduced almost to zero.
The materials used for the construction of the pump make it particularly suitable for aggressive liquids.
The metering pump has been designed to feed liquids with capacities from 0 to 15 l/h and pressures from 0 to
15 bar (depending on the model selected).
2.2 - COMMON FEATURES
• The products are manufactured according regulation.
• IP 65 protection.
• Antiacid plastic casing.
• Control panel protection assured by an adhesive polyester film, weatherproof and resisting UV ray
• Standard power supply:
230 V a.c.50 Hz single phase.
• Optional power supply:
240 V a.c.50-60 Hz single phase;
110 V a.c. 50-60 Hz single phase.
Upon request: manual stroke lenght adjustment. This control provides accurate flow adjustment. (only DLXB
series)
OPERATING FUNCTIONS:
Manual The pump can be programmed to operate in one of the following ways:
Operating range: 0 – 120 pulses per minute
0 – 120 pulses per hour
0 – 48 pulses per day
1xN When a pulse generating water meter is connected to the pump, every pulse received will
cause the pump to pulse N times. Operating range: 0 – 999 pulses for each contact
0 – 120 pulses per minute
1xN(M) Every pulse from a water meter will cause the pump to pulse N times. While the pump is
pulsing, it still registers all further signals received (M) and translates them into succes-
sive pulses. Operating range: 0 – 999 pump pulses (value of N) for each signal received
1 : N Every N number of signals received on the connector, the pump supplies an injection
0-999 pulses for each contact
