SEKO digital pump
SEKO-Elektra Series Digital Pumps
The Elektra Series digital pump is a flow-metering pump designed to allow customers to operate it via smart devices or traditional electronic displays, achieving precise digital dosing control and remote data management.
4-20mA Analog Signal Input and Output
Analog signal 0/4-20 and 20-4/0MA proportional speed input: the input signal is interlocked with the pump, and users can customize the upper and lower dosing limits. Analog signal 4-20MA output enables more convenient and rapid connection with integrated devices.
Real-Time Data Acquisition
Instantaneous values: Through the pump panel or communication connection, users can obtain the real-time status of the pump, including dosing flow rate, alarms, and operating mode.
SEKO aims to help users save operating costs as much as possible under increasingly complex application and installation conditions through real-time data management. The Elektra Series helps cost-conscious enterprises achieve continuous, stable, and precise dosing while keeping costs under control.
Stable accuracy after calibration* up to +/-1%
- Features precise dosing and stable operation. After calibration, the accuracy of the Elektra Series digital pump can reach +/-1%, making it the ideal choice for users with high dosing accuracy requirements. The Elektra Series is designed to allow customers to operate it via various smart devices or traditional displays, achieving precise digital dosing control and remote data management, thereby further helping to reduce operating costs.
Modbus RS485 Communication Protocol & Wi-Fi Connection
The Modbus standard protocol refers to cross-device connection and communication, allowing users to establish a wired network of standard Modbus devices. Elektra can be used in large facilities composed of multiple industrial devices, all of which can be controlled by local controllers such as PCs or PLCs.
Built-in Wi-Fi allows users to connect directly to the device locally and remotely via the SekoWeb channel or APP.
