Part of future water solutions
In addition to drinking water supply the
SP pump is also a preferred product for
irrigation, where new digital solutions can give
farmers the opportunity for remote control
and monitoring of the irrigation system. The
stainless steel construction makes the SP
pump very resistant, therefore it is also used
in mining, wherein a rough environment makes
great demands on the durability of the pump.
These days, there is also an increasing focus
on not only energy efficiency, but also water
efficiency.
“We must make sure that we use the
groundwater resources that are available as
wisely as possible. The potential of digitalizing
irrigation systems is big and because the SP
pump is an obvious candidate to be part of
these solutions, it can play a crucial role in
solvin g the serious water challenges the world
is facing”, says Søren Skjalm-Rasmussen.
Milestones on cutting-edge
technology
Since 1967, the journey of the SP pump has
featured several developmental milestones
for Grundfos’ submersible pump program. In
1982, the introduction of the spline shaft in
pumps for private water supplies cut down
significantly on production time and material
consumption, and in 1992 motors with built-
in micro frequency converters were launched.
When the latest generation of SP pumps with
the name SP7/9/11/14 was launched in 2014,
the energy efficiency was taken to a whole
new level. Not only did it live up to, but it
exceeded EU requirements for
energy efficiency of water pumps.
Many new application opportunities have also
been added. With the Grundfos Solar Inverter
(RSI) it is e.g. possible to connect the SP pump
to solar cells and thereby utilize sustainable
energy, also in areas where a stable power grid
is not available.
It is estimated that there are currently about
1.3 million SP pumps installed worldwide.
The many new additions and application
options makes the SP pump a thriving classic,
which now has proven its viability throughout
50 years, and which undoubtedly will be a
cornerstone of the Grundfos pump range for
years to come.
