BOILERS AND SYSTEMS | Make valves redundant
FROM SPEED-CONTROLLED PUMPS TO INTELLIGENT SYSTEM SOLUTIONS
A pump does not exist in isolation. A pump is always part of a larger system, working together
with a whole range of other components. That is why we think beyond the pump and take the
entire system into account when developing new solutions. Our E-solutions and Grundfos
iSOLUTIONS are both testimony to that.
What are E-solutions?
A Grundfos E-solution features pump, motor and frequency drive all in one product. As the
frequency drive constantly adapts pump speed according to demand, it is possible to achieve
significant pump energy savings.
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
WHY FOCUS ON SYSTEM INTELLIGENCE?
Reduced downtime and maintenance costs
- Improved system reliability:
Optimised process control through targeted functionality and extended measuring capability
- Better system performance:
Built-in functionalities substitute external components and control equipment
Reduced energy consumption in the entire installation
- Best-in-class energy efficiency:
As much as 70% of all boiler systems run inefficiently. And often this can be traced back to the
level control system in the boiler feed. With our E-Solutions you can reduce pressure loss across
feeding valves, or you can go with a Grundfos iSOLUTION and control the level directly. This will
make valves redundant and make your boiler system more simple and efficient.
Frequency drives allow you to maintain
constant pressure in boiler systems operating
with feed valves on one or multiple boilers.
Set the pump for direct level control and
eliminate both feed valve and bypass. This
allows for smaller pumps, because the pumps
do not have to compensate for pressure loss in
the feed valve and flow through the bypass.
Pump curve stabilizing
Unstable pump curves can be stabilized with
the built-in pump control. You avoid the
regulating challenges associated with flat pump
Run at power limit
Run pumps at full load power output but with
optimal overload protection. This allows for
operation with undersized motors.
Monitor the process, get useful data to
improve performance and connect directly to
the overall process control.
Feed pump control
Control one or more feed pumps from the main
Control of external equipment
Control external equipment, e.g. bypass
valves, according to the pumps’ operating
Set point influence
The boiler pressure may influence the set point
of the pump. Reduce the pump’s discharge
pressure when the boiler pressure is low to
avoid cavitation during start-up and blow out.
Duty standby/duty assist
Manage boiler feed systems with two pumps in
pumps up to assist each other when the
nominal flow is exceeded in order to prevent
