Advantages of speed control
Adaptation of performance through frequencycontrolled
speed control offers some obvious
advantages:
Energy conservation
An E-pump uses only the energy required for the
pumping application. Compared to other control
methods, frequency-controlled speed control is the
method offering the highest efficiency and thus the
most efficient utilization of the energy. Depending on
the application and pump type, savings of up to 50 %
or more are realistic.
Low operating costs
The efficient utilization of the energy offers the
customer an attractive reduction of his/her operating
costs. This is seen in the form of lower daily energy
costs, but also in the form of lower wear on pumps and
system components which again reduces the need for
replacements.
Applications
Overview of applications
E-pumps can be used with advantage in many
applications falling into one or more of the following
three groups:
• E-pumps will generally be very beneficial in all
pump applications with a varying demand for pump
performance. Using E-pumps will result in energy
saving and/or improved comfort or process quality,
depending on the application.
• In some applications, E-pumps will reduce the need
for control valves and costly components. In many
cases, E-pumps can reduce the total system
investment.
• E-pumps can also be a very good choice in
applications where communication between the
different units in the system, such as pumps, valves,
etc. and the control system is required.
Product overview
Protection of the environment
The efficient utilization of energy offers some
environmental advantages in the form of less pollution.
Pumps using less energy demand less power from the
power stations.
Increased comfort
For the customer, controlled operation of the pumping
system means increased comfort due to the automatic
control and a lower noise level from pumps and
pipework, etc.
