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 LP series is available in five capacity ranges. The MEMDOS SMART LP's drive is fully adjustable. For integration into demanding automation networks, a version with an Ethernet-based MODBUS interface is available.
