The SP system | Strength all the way
Continue... 2                              <Previous Page>
Expert design, expert tests
The current SP pumps are the result of decades of experience and
constant improvements. This has let us perfect our production methods
to optimise quality, so you can put the SP to the test with complete
confidence. In fact, we have done it before you. Every pump is tested
before it leaves the factory to make sure that when you choose the
original, you get the best.


You can see for yourself what the SP is all about. All the technical
documentation you could ever want is available online or from your
Grundfos supplier.

MS/MMS – motors
that improve performance
Quality from one of the world’s largest motor
manufacturers

Grundfos has been making submersible motors for more than 30 years and is
now one of the world’s largest manufacturers of high-quality submersible
motors. The MS and MMS submersible motors are not only rated among the
very best on the market for use with submersible pumps of any make – they
are also designed to be the perfect fit for the SP pumps, matching their best
duty points.
Canned MS, rewindable MMS

These all-stainless steel, water-filled motors are available in two basic versions
in a variety of sizes from 4” to 12”. The MS series of canned submersible
motors comes in sizes up to 30 kW (40 hp), while the MMS series of rewindable
motors come in sizes up to 250 kW (340 hp). Special versions for demanding
industrial use are also available.
The motor is as important as the pump

When you require high efficiency, the motor is just as important as the pump.
Hydraulic efficiency will not do it alone. The MS and MMS motors match the
advanced hydraulics of the SP range. And they will continue to do so: Durable
shaft seals and heavy-duty thrust bearings are just two of the features which
make the MS and MMS pumps so long-lived.
MS: Compact and efficient
The MS range of canned submersible motors comes in
sizes of 4” and 6” in two main versions: MS 402 and MS
4000/MS 6.

MS 402
MS 402 is designed for the domestic ground water market
and covers outputs up to 2.2 kW (3 hp).

MS 4000/MS 6
The MS 4000 and MS 6 series cover a range of water
supply applications that require power up to 30 kW.

All external surfaces of Grundfos MS motors in contact
with water are made of stainless steel DIN W. Nr. 1.4301
(AISI 304) unless otherwise specified. R-versions made
from DIN W. Nr. 1.4539 (AISI 904 L) are also available
for aggressive water.

MS motors are fitted with a built-in Tempcon sensor to
prevent overheating – a solution which together with a
Grundfos MP 204 eliminates the need for external
temperature sensors.

MMS: Powerful, efficient, and
easy to repair
The MMS range of rewindable motors is available in sizes
6”, 8”, 10”, and 12” up to 250kW. They are suitable for
any submersible installation, including heavy-duty
industrial applications and dewatering operations.
