Stepper motor-driven diaphragm metering pumps

Stepper motor-driven diaphragm metering pumps are particularly suitable for highly accurate, reproducible industrial dosing thanks to their design. Many fluid media can be safely fed into the respective processes using these pumps. The stepper-motor with its wear-free tooth belt drive, ensures a particularly homogeneous and gentle dosing process.

MEMDOS SMART LDX, LAX, LPX


Reliable dosing of chemicals

The new generation of the stepper motor-driven diaphragm dosing pump MEMDOS SMART provides a wide range of attractive solutions for demanding dosing tasks. The new stepper motor technology permits high-accuracy dosing of even the smallest volumes. Asynchronous running with various speeds of the suction and pressure stroke enables homogeneous and pulse-reduced dosing. The further development of the Slow mode permits the transport of highly-viscous media at even greater levels of reliability and reproducibility.

Available in seven versions, the new generation of the MEMDOS SMART provides a range of different functionalities. Two sizes of the MEMDOS SMART series are available. 

Several different materials and connections are available for suction and discharge side, depending on the specific applications.

Precision that inspires

The MEMDOS SMART stepper motor-driven diaphragm dosing pump provides a wide range of solutions for high-precision and demanding dosing tasks. Its advanced drive system means that it is able to process even the smallest quantities with a high degree of accuracy. Homogeneous and low-pulsation dosing is made possible by asynchronous operation, in which the suction and pressure phases run at varying speeds.

Different materials and connections for the pressure and suction side of the dosing pump can be selected according to the specific requirements. Accessory sets consisting of a hose, injection nozzle and suction line are available to enable optimal results and quick installation.
