The mechanical seal can be replaced without

removing the pump housing from the piping.

If a replacement pump is not immediately available,

a special blanking plate can be used to close the

pump housing.

Stand-by implementation: continuity or extra capacity

As an option, two Omegas can be used in a redundant implementation for extra capacity or reliability.

The stand-by pump is switched on by the control system when necessary.

Omega DSL Omega DS

Wide choice of motors

Made with a standard motor that was developed

speci� cally for this pump series, the Omega is

particularly energy ef� cient. Smart controls enable

the optimal speed to be set. For a higher ef� ciency

an IE4 motor is available.

Tailored control system

Choosing the correct frequency drive depends on a

lot of factors: how and where the pump will be used,

the � ow pattern, whether or not output sensors are

needed, integration in existing building or process

management systems, etc. Our sales engineers

determine the optimal choice for each case and

advise you accordingly.

Every project and application deserves a high-quality circulation pump that

is easy to set up and can quietly do its job ef�ciently for many years. Get to

know our circulation pumps, they are guaranteed to get the maximum out of

every process.

compact circulation pumps for big performance

Energy-ef�cient, self-regulating circulation pump

The SimFlex circulation pump is an excellent choice

for a surprising number of applications. The SimFlex

can operate at a constant or proportional pressure or

be set to run automatically at optimal speed.

The pump reacts to resistance/pressure changes

caused by opening or closing thermostats. Needless

to say, this pump meets the latest ErP standards.

Night mode

The integrated ‘Night mode’ function enables the

energy consumption to be reduced to a minimum

during periods when there is a low demand.

Long life

The pump’s long life is achieved by using a quiet,

permanent magnet motor and ceramic bearings with

a long service life and high-quality components and

materials.

Easy to exchange

The compact design and standard connections mean

that the SimFlex always �ts in existing systems and

can therefore be easily exchanged with other brands

of circulation pumps.

Other featuresnThe standard venting plug is easily accessible and

suitable for the removal of contaminants from the

system.nThe compact illuminated display on the pump

continuously displays the power consumption (Watts),

and any error possible codes. nProtected against excessive starting currents (> 2.5A)

caused by external control.

Eco Mode with integrated speed control

By default prepared for building management systems

* When compared to circulators with constant or proportional pressure.

Up to 40%* additional energy savings

In circulation processes, it’s all about

user comfort. The Magneta Smedegaard

series almost silently and automatically

ensures the reliable circulation of water in

heating and air-conditioning systems.

Eco Mode

The Magneta Smedegaard has various standard

settings, including ‘constant or proportional pressure’

and an Eco Mode. In the Eco Mode the pump

supplies the required pressure and output with

continuous adjustment and as ef� ciently as possible

by making use of its integrated smart speed control.

The result is optimal comfort and minimal energy

consumption.

Magneta Smedegaard D(ouble), extra reliable

The Magneta Smedegaard D model provides extra

operational assurance due to its con� guration of two

Magneta Smedegaard pumps and a special manifold

with integrated check valve.

User-friendly operation panel

Permanent magnet motor

Standard connections

The standard control system provides an automatic

pump change-over, for instance in case of a failure

in one of the pumps or after 24 hours of operation.

The pumps can also be used simultaneously for a

higher capacity.

40% of the life-cycle costs of a HVAC pump consist

of energy costs. Therefore, the ef�ciency of the

hydraulic design and a well-selected and tuned pump

can make a signi�cant difference in the total cost.

The hydraulics of the norm pump impeller can be accurately

adapted to the operating point and, as standard, the pumps

are �tted with energy-ef�cient motors that are suitable for use

in conjunction with a frequency converter to ensure optimum

ef�ciency is achieved for every application.

We would be more than happy to support you in making the

most energy-ef�cient choice for your application.
