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 LK series is available in five capacity ranges. The MEMDOS SMART LK's drive is fully adjustable.
In addition, the MEMDOS SMART LK gives you the possibility to reduce the suction speed in two steps to easily and more precisely dose even viscous dosing media.
