Microprocessor-controlled diaphragm metering pump MP-PVDF for conveyance of medium to largest volume flows for variable metering and process tasks.
Low-noise, oscillating displacement pump with electric drive and cam / spring follower mechanisms.
Direct adjustment and control of dosing capacity in plain language via a big illuminated LC display.
3-LED-function as operation indicator, alarm indicator and fault indicator.
Microprocessor control: optimum combination of variable AC frequency combined with digital stroking frequency, ensures exact metering even in the lower minimum range due to individual stroke control.
Control via external contact (pulse)
Control via analogue signal
Linear regulation of metering capacity by stroke adjustment in 1 % steps.
PTFE-multilayer safety diaphragm with visual diaphragm rupture indicator, i.e. even should the diaphragm rupture the feed chemical cannot escape from the pump unchecked or penetrate the pump drive.
Ball valves for suction and pressure side
High-strength inner housing for energy-stressed components as well as additional polymer housing as protection against corrosion.
Time-controlled chemical addition
Quantity-proportional chemical addition
Measurement-dependent chemical addition, e.g. acid and brine dosing
Pulse-controlled dosing, e.g. when bottling different volumina
