Digital dosing pump – DME 940-4 B
Compact positive displacement diaphragm dosing pump, with integrated variable speed motor drive in a IP65 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
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 the same accuracy and 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.
A unique drive technology and microprocessor control make sure that liquids are dosed precisely and with low pulsation, even when the pump is operating with high viscosity or degassing liquids. Instead of the conventional stroke length adjustment, the capacity of the DME is regulated by automatic adjustment of the motor speed during the discharge stroke, and by fixed suction stroke speed. This guarantees optimal and uniform mixing.
