STEPPER MOTOR PUMP
FOR DEMANDING METERING REQUIREMENTS
The new iSTEP XS stepper motor pump by sera combines an intelligent drive concept with the accuracy of a diaphragm dosing pump and sets standards with regard to reproducibility and reliability. By means of the variable frequency control and a power range of 0.007..15 l/h at 10..7 bar, the application possibilities are almost unlimited. It is intuitive to use, long lasting and is particularly suitable for demanding dosing tasks.
SCOPE OF APPLICATION
Chlorine dosing for the treatment of drinking water
Flocculating agent dosing in wastewater treatment
Dosing of flocculant aids
INPUTS & OUTPUTS
3 inputs programmable as
3x digital inputs
2x analogue inputs 0/4...20mA
2 digital outputs
1 analogue output for 0/4...20mA signal
All inputs and outputs can be freely parameterised
OVERVIEW OF ADVANTAGES
- Extremely high performance range with only one pump
- Adjustment range 1:1000, thereby optimally adaptable
- Low-pulsation dosing
- Microprocessor-controlled drive
- Remote execution
- Energy-efficient drive technology
PROFIBUS- / PROFINET- INTERFACE MODULE (OPTION)
The Pro+ control electronics of the iSTEP can be expanded by interface modules for PROFIBUS or PROFINET networks.
The PROFIBUS INTERFACE MODULE has a level in- put and two connections, with which the iSTEP can be directly integrated into a bus system. The connec- tion / termination directly on the module. Additional distributors are not required.
The PROFINET INTERFACE MODULE offers the possi- bility of integrating the dosing pump into a ProfiNet network. With two ProfiNet connections, it can be integrated in both ring and tree structures.
