Grundfos: How is the pump doing?

grundfos_pressebild_grmWells, waste water treatment plants, water reservoirs, elevated tanks, water distribution networks, collection channels, rainwater retention basins, waste water treatment plants – the water industry operates a complex network infrastructure for water supply and waster water disposal.

The high fixed costs of these infrastructures force those responsible to an intensified view of the variable costs. This can only be done by the energy efficient operation of all technical units, in particular the pump system. The basis for this is the transparency by the recording and analysis of the relevant energy data. However, pumps in small and medium-sized water treatment and sewage treatment plants generally do not operate in the view of a technician. And the distance to a central control panel makes the connection of a cable impossible from the aspect of costs.

In order to enable the remote access, Grundfos has developed a pump-specific “Remote Management” GRM: a high-performance internet- based tool for remote control and remote monitoring of pumps and systems.

For this purpose, the pumps, sensors and control systems are connected to a data logger that sends the data collected to a central server wireless per mobile radio (GPRS or GSM) several times a day – as a result, the operating company is provided with an internet site with a complete overview of the state of the pumps installed.

Using a smartphone, tablet or computer with internet access, users are able to log into the password protected user interface of the GRM at any time and from anywhere via internet. The tool provides an overview of all pumps and installations of the system connected. In doing so, one has access to data such as operating hours, operating points, setpoints, sensor values, reports, trends, alarms, warnings, etc. In certain cases, you are also able to intervene per remote monitoring such as, for example, when the motor protection has tripped and the motor has to be restarted via the remote connection.

The precise overview of the pump performance supplies valuable data in order to optimise the system. Tools such as automatically generated trend graphics help to recognise signs of wear or damage at an early stage, and plan servicing and maintenance work with sufficient fore run. Moreover, the remote monitoring permits an efficient alarm management with short reaction times which increases the operational safety of the system.

An interesting point for waster water disposal companies: Dedicated Controls, the intelligent control for the control and monitoring of up to six waste water pumps in a pump station that can be integrated in the GRM system.
