MEMDOS SMART LD
Precision that inspires
The compact stepper-motor pump, coupled with its intelligent drive concept, combines the big advantages of a solenoid-driven diaphragm dosing pump with the precision of a motor-driven diaphragm dosing pump.
The MEMDOS SMART LD series is available in five capacity ranges.
The MEMDOS SMART LD's drive is fully adjustable. Using position detection in the pump, after an unexpected shut down of the pump, overdosing can be prevented and downtime resulting from this can be excluded.
