Operation
Dosing modes
Constant
The pump doses at a constant frequency, according to the flow rate percentage set with the stroke length adjustment knob of the diaphragm.
Models: Prius D MF, Prius D AP MF, Prius D, Prius D AP
Pause / work
The pump runs the programmed cycle: during the WORK time it doses the set quantity of chemical; during the PAUSE time dosing is suspended.
Models: Prius D MF, Prius D AP MF
Pulses
The pump doses in proportion to the pulses received from an external controller.
Models: Prius D MF, Prius D AP MF
PPM
Dosing is calculated from the pulses of the pulse-output water meter and the set PPM value; the concentration of the chemical and the volume per stroke can be programmed.
Models: Prius D MF, Prius D AP MF
Millilitres per quintal
Dosing is calculated from the pulses of the pulse-output water meter and the set MLQ value (millilitres per quintal).
Models: Prius D MF, Prius D AP MF
Percentage
Dosing is calculated from the pulses of the pulse-output water meter and the set percentage (%).
Models: Prius D MF, Prius D AP MF
Batch
A pulse from an external contact starts the dosing of the set quantity; pause and work cycles can be programmed.
Models: Prius D MF, Prius D AP MF
mA
The 0-4/20 mA current signal controls dosing proportionally, between the set minimum and maximum values.
Models: Prius D MF, Prius D AP MF
Volt
The 0-10 V voltage signal controls dosing proportionally, between the set minimum and maximum values.
Models: Prius D MF, Prius D AP MF
Timer
Up to 16 weekly on/off timers can be programmed, during which the pump doses the set quantity of chemical.
Models: Prius D MF, Prius D AP MF
Colour display
Colour-coded status indication
In the MF models the display colour changes according to the operating status, so that an alarm can be recognised even from a distance.
Green
Normal operation according to the set parameters, no active alarms.
Yellow
Non-blocking alarm, for example waiting for an external signal.
Red
Blocking alarm, for example the chemical in the tank running out.
White
Pump stopped by an external control signal (stand-by).
Remote control
Remote control
The MF models can be integrated into your control system via Modbus RTU, or they can send a read-only 4/20 mA signal.
Integrated Modbus RTU Optional
Integration into your PLC: all pump parameters can be managed from your control interface.
4/20 mA output Optional
Current signal proportional to the instantaneous flow rate, to be fed to your PLC / SCADA for remote monitoring of operation (read-only).
Technical data
Performance and configurations
Performance depends on the model, the working back-pressure and the number of strokes per minute. As the viscosity of the product increases, a pump with a lower number of strokes per minute is recommended.

Insight: the pump does not prime and does not dose →If the pump…
Insufficient or no flow rate
- Air in the pump head or in the suction tubePrime the pump until all the air has been expelled.
- Suction valve or tube obstructed or not sealingClean or replace the suction valve; replace the tube.
- Foot filter cloggedClean the filter.
- Excessive suction height relative to the tankReduce the suction height.
- High-viscosity liquidUse a larger-diameter suction tube.
Overheating of the motor and pump head

| Message | Meaning | Action |
|---|---|---|
| LEVEL | Chemical in the tank has run out. | Restore the chemical level in the tank. |
| OVER FLOW | The required flow rate exceeds the rated value. | Check the settings and the flow rate, then switch the pump off and on again. |
| HIGH VOLT | Supply voltage above the permitted limits. | Check that the voltage matches the rating plate data; if the pump has locked out, switch it off and on again. |
| LOW VOLT | Supply voltage below the permitted limits; after 5 alarms within two minutes the pump locks out. | Check the mains voltage, then switch the pump off and on again. |
| ANOMALIA IMPIANTO | Sudden stop of the pump or motor (system fault). | Identify and eliminate the cause of the stop, then switch the pump off and on again. |
Red display: alarm; yellow: warning; green: normal operation; white: stand-by or OFF. Active alarms can be viewed under SETUP › INFO › ALARMS.
First start-up
Start the pump with the stroke length set to 20% and minimum back pressure; after about 5 minutes increase it gradually. If the pressure exceeds the rated value, stop the motor immediately.
Oil
Check the level using the dedicated indicator and never run the pump without oil; change it every 8,000 – 10,000 operating hours and in any case at least once a year.
Periodic checks
Every three months check bolts and seals; once a year check that flow rate, pressure and power match the rating plate data. With abrasive or corrosive chemicals, shorten the intervals.
If the problem persists, contact us. Before sending the pump for servicing, empty the pump head of chemical and dry it.
Summary
Main features
Electronic flow rate adjustment
According to the operating mode and the set parameters, the pump automatically adapts the injection frequency to ensure the required dosing.
Models: Prius D MF, Prius D AP MF
Mechanical flow rate adjustment
The knob reduces the stroke length of the diaphragm, i.e. the volume of each injection and, consequently, the maximum flow rate. This offers two advantages:
Linear dosing: a high number of small-volume injections promotes mixing of the chemical into the water flow and avoids concentration peaks.
Accuracy at low dosing rates: with a 10 l/h pump required to dose 1 l/h, reducing the stroke length to 50% brings the maximum flow rate down to 5 l/h and doubles the injection frequency. Particularly suitable in combination with the pulse-output water meter.
Digital display
The integrated LCD display allows the pump to be programmed and its operating status to be monitored at all times.
Models: Prius D MF, Prius D AP MF
Level control
The pump is supplied with a low-level probe for the tank: when the chemical runs out, it shows the alarm on the display and activates the corresponding output.
Models: Prius D MF, Prius D AP MF
Stand-by
Pump start and stop can be controlled remotely by means of a run/stop contact from a PLC or another source.
Models: Prius D MF, Prius D AP MF
Flow sensor
A flow sensor can be connected to check every single injection: if one or more injections are missed, the pump performs an automatic re-priming and recovers the lost injections; if this fails, it activates the alarm output.
Models: Prius D MF, Prius D AP MF
Alarm output
In the event of a fault, a volt-free contact is activated, configurable as normally open (N.O.) or normally closed (N.C.), to drive a visual or audible signalling device, send an SMS or report the event to a PLC.
Models: Prius D MF, Prius D AP MF
