2.0 - DLX AND DLX/B SERIES METERING PUMPS
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 bar (depending on the model selected).

•
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.
•
Connections for level probe, flow sensor, water meter and relè output (activated by flow alarm (AL2) and too
many pulses alarm (AL3)).
• Upon request: manual stroke length adjustment. This control provides accurate flow adjustment. (only DLXB
series)
Operating functions:
Manual
The pump can be programmed to operate manually from 0 to 100% of flow.
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
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
