Demand-controlled pumps
Tailored to the needs of pump installations,
the new GP variable speed drive supports
optimum operation with an active and
intelligent control – keeping you on the
safe side and reducing operating costs.
Intelligent functions for enhanced safety
As standard, the GP can detect a variety
of events, such as when:
• Pump is blocked or running dry
• Motor is overloaded
• Pipes have burst or are leaking
• Pump is running outside the
characteristic curve
In each of these potentially dangerous
scenarios, the GP protects your plant
– either by triggering an alarm, decreasing
the motor’s speed, switching the pump off,
or performing a programmed action. And
when the pump is not needed, the smart
hibernation mode can prevent unnecessary
wear and tear – and save you even more
energy. The integrated real-time clock with
three programmable timers allows you to set
the running times of the GP individually.
Your partner for planning
To achieve this level of intelligence, careful
planning is necessary. The pump must be
appropriately sized and the pressure sensors
correctly placed. Of all the variable speed
drive manufacturers worldwide, Siemens is
the only one offering in-depth HVAC experti-
se together with a comprehensive portfolio
of perfectly matched components. As your
partner, Siemens helps you maximize safety
and convenience, limit energy consumption
and reduce operating expenses.
