What is Grundfos iSOLUTIONS?
Grundfos iSOLUTIONS is the latest addition to Grundfos’ portfolio and takes intelligence to a brand new level. Where E-solutions primarily offer focus on product level, iSOLUTIONS will extend savings to the entire system; optimising the way pumps, drives, controls, protection, measurement and communication units work together.

According to US and EU energy savings studies, the biggest savings potential lies in better system control. In fact, a holistic approach will on average cut as much as 20% of the total energy consumption of your application.

For example if you have a process where you need to Heat or Cool a fluid using a heat exchanger / Plate Type heat exchangers (PHE) / Brazed plate heat exchanger (BPHE/CBE) or any other type of process where you are controlling the temperature. Normally you would require a Pump, Temperature Sensor, VFD or PID control Valve, PID controller and than you can control the process at a certain temperature. This complete list of equipment can be replaced with Just on Grundfos iSOLUTION pump. Pumps works has a inbuilt VFD, PID controller, Temperature or pressure sensor input, communication output to your monitoring system, and alarms. this helps you in optimizing the system and saving energy to a great extent.  

Let’s have a quick view of some of the most prominent ways Grundfos iSOLUTIONS can upgrade your system.

Process optimisation

Monitor pump influencing conditions and control other equipment to ensure optimum operation of the entire process.


Open up for monitoring and surveillance of additional process parameters and connect directly to the overall process control through a variety of industrial busses.

Limit exceed

Enable your system to change operating patterns or notify you directly if a specific process parameter exceeds a pre-set limit.

Multiple temperature measurement

Use the same measuring point for three purposes: As a primary control parameter, as part of a differential temperature measurement for set point influence or as a limit exceed response.

Dry-running protection

Avoid overheating and pump damage caused by dry-running. The directly connected Liqtec dry-running protection detects lack of water and too high liquid temperatures.

Underload detection

Enable your system to detect cavitation or prime loss in the pump and bring operation to halt before damage.

Set point influence

Link the primary control parameter to an external signal or internal measurement and automatically adjust it to best suit the process conditions.

Break tank and feed pump control

Control and supervise the break tank level and the feed pump directly from the motor to save wiring and other control components.

Process surveillance

Measure a range of secondary parameters and program a proper response.

Control of external equipment

Control external equipment according to the pumps’ operating conditions, e.g. open bypass valves, start air injection or control mixing loop.

Valve control

Control the opening and closing of motor-operated non-return valves by means of a timer function in the pump.

Backwash control

Enable system to initiate backwash sequence, controlling main pump, backwash pump, dosing pump and valves by measuring the condition of the filter. The sequence can be set up through a combination of measurements and timer function.

Set point influence

Avoid cavitation or excess pressure across the chamber stack by adjusting the set point of the pump. Influencing parameters include pre-pressure, flow, temperature, etc.

Break tank and feed pump control

Control of one or more feed pumps can be operated from the main pump control. Level control in the feed tank can be controlled and supervised from the main pumps.

External control

Set up a multi-pump unit to operate and appear as one single pump (open loop) and be controlled from external control system – or a pump unit can do surveillance and monitoring, and feed process data to the process control, while it simply operates at constant set point feed from the overall control system.
