    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 operating panel with one-touch buttons and a multilanguage backlit display. The capacity to be dosed in each function is set directly in l/h, ml/h or USgal/h. 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/h, l/h or USgal/h.
    • External pulse control from external controller or water meter with direct setting in ml/pulse.
    • External analogue 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 number of pump strokes, operating hours and power on and off
    • 14 optional display languages
    • input for low-level and empty-tank signals
    • alarm relay output
    • overload protection.
