Hello, नमस्कार, Bonjour, Hola, Ciao, Guten Tag, Ola, اهلا و سهلا, 你好, Привет, Γειά σου, Goededag, G’day

 

Thank you for visiting our website. Here you can find out how to reduce energy and maintenance costs for your pump systems, and improve availability.

 

Continuous monitoring with MicroPM™ pump monitors fitted to every pump gives the most benefit.

 

The MicroPMs can interface with a single MicroStM™ Station Monitor in each pump station, to provide pump scheduling, local HMI, and easy connection to PLC/ SCADA

 

Remote monitoring services with monthly summaries can be provided.

 

Pump test services with portable units (P22) are also available. Blowers and hydro-turbines can be monitored similarly.

 

Please REGISTER to receive updates, and interesting and relevant case studies on a regular basis.

Rapidly identify excessive wear and other pump system problems.
