DME940-4AP SS/T/SS-S-31A2A2F
Compact, positive displacement diaphragm dosing pump with integrated variable-speed motor drive in an IP65 plastic enclosure. The pump is designed for optimum user-friendliness, accuracy and reliability and is equipped with a logical control panel with one-touch buttons and a multi-language backlight display. The capacity to be dosed in each function is set directly in l/hour, ml/hour or USgal/hour. For enhanced accuracy, the pump can be calibrated to the actual installation by means of a simple calibration function. The turndown ratio is 1 to 800 with unchanged accuracy and more uniform dosage with reduced pulsation throughout the capacity range. The pump is also equipped with a maximum capacity function (100 %) that allows the pump to work for a preset time at maximum capacity for priming or ordinary maintenance without changing pump settings.
The wetted parts are the following:
- Pump head
- PTFE-coated diaphragm
- Ball valves
- Manual bleed valve.

Possible operating modes:
- Manual dosing with direct setting in ml/hour, l/hour or USgal/hour
- External pulse control from external controller or water meter with direct setting in ml/pulse
- External analog 4-20, 20-4, 0-20 and 20-0 mA control with possibility of adjusting the pump capacity at maximum signal
- Timer-based batch function (internal timer)
- Pulse-based batch function (external pulse).

Other features:
- Built-in module for bus communication with PROFIBUS DP systems. The module enables remote monitoring and setting via this fieldbus system.
- On-site calibration function for calibrating the pump to the actual installation
- Anti-cavitation function for high-viscosity, degassing liquids or long suction lines
- Maximum capacity limitation
- Counters for numbers of pump strokes, operation hours and power on/off
- 14 optional display languages
- Input for low-level and empty-tank signals
- Alarm relay output
- Overload protection.
