<Diaphragm damage detection>
If the diaphragm is damaged during operation, a liquid leak is detected and the pump operation is stopped.
<Relay output>
Alarm relay ： Outputs a non-voltage contact signal when an abnormality such as a defective pump or a low liquid level in a chemical tank occurs
Pacing relay ： Outputs a non-voltage contact signal for each diaphragm stroke

Suction Stroke Mode (4 Types)
| Mode | Image | Viscosity | Max Stroke Rate (spm) Pump Capacity(%) |
|---|---|---|---|
| Normal |  |  | 200 / 100 |
| HV1 |  | 160 / 80 | |
| HV2 |  | 120 / 60 | |
| HV3 |  | 80 / 40 |
Discharge Stroke Mode (5 Types)
| Mode | Image | Application |
|---|---|---|
| Optimum |  | For maximum precision when metering and the very best results with internal pressure measurement and special functions. |
| Fast |  | For as fast a discharge stroke as possible – the duration of the discharge stroke is dependent on the stroke rate. |
| Sine mode |  | The duration of the discharge stroke is dependent on the stroke rate for a long, sine-shaped pressure stroke. |
| Continuous |  | For a continuous discharge stroke e.g. for bottling processes. The duration of the discharge stroke is dependent on the stroke rate. |
| DFMa |  | For optimum operation with a flow meter DulcoFlow® DFMa. |
<External signal operation>
Supports pulse signal, analog signal, and remote ON / OFF operation
<Various abnormality detection>
Detects pressure abnormality, gas lock, analog signal input abnormality
Can be connected to a contact output type flow monitor and the flow meter “DULCOFLOW” dedicated to metering pumps
<Timer operation>
Automatic operation can be set by day of the week and time
