The sera stepper motor pump iSTEP combines an intelligent drive concept to the accuracy of a diaphragm dosing pump to provide state of the art technology when it comes to accuracy, versatility, ergonomics and reliability in fluid dosing. As the pump is equipped with a multilingual, intuitive menu navigation and a power supply of 110-240 V, 50/60 Hz it can be used worldwide.

The new released sera Interface Module enables the iSTEP to be integrated into a PROFIBUS system. PROFIBUS, especially PROFIBUS DP, is used to control and operate sensors and actuators via a centralised controller for automated manufacturing applications. Besides the various standard diagnostic options, the focus is on integrating multiple controls together.

The installation is very easy: A usually needed Y-junction is not necessary, as the sera Interface Module is equipped with a separated input and output. Also the included wall brackets enables module mounting adaptable to both the pump and a location elsewhere. 

Pumps equipped with the sera Interface Module can be controlled and managed centrally: a data transmission and parametrisation of several pumps is also possible without hand-held control element. The sera Interface Module supports both standards DP-V0 and DP-V1 and thus can be used either in process and automation technology or in process engineering.

The sera Interface Module is offered as an option for every iSTEP and needless to say, it can be retrofitted as well.

With the sera Interface Module we can meet increasing demands for future production processes: PROFIBUS connections lead to an intelligent, sustainable and especially efficient control system. Appropriate product adjustments will be made to utilize the sera Interface Module for further pump series.

The advantages at a glance:

  • Central control and parametrisation of diaphragm dosing pumps
  • Standards: DP-V0 and DP-V1
  • Easy installation due to separate input and output
  • Available as an option for every iSTEP



PROFIBUS (Process Field Bus) is a standard for fieldbus communication in the automation industry. There are three PROFIBUS variants, with PROFIBUS DP being the most common. PROFIBUS DP (Decentralised Peripherals) is used to control and operate sensors and actuators via a centralised controller in production (factory) automation applications.
