EFFICIENCY
Reduce your
operating costs
The total cost of owning and operating a pump over its entire
lifespan covers much more than just the initial cost – it covers
the total sum of the Life Cycle Costs of the pumping system.
Electricity is the most expensive part of any pump – a fact that
is often overlooked when pumps and prices are compared. It
maybe surprising that the purchase price and maintenance
costs account for less than 15% of the total lifetime cost of
a pump. Electricity accounts for a staggering 85% or more of
the total costs. If you want to save money, that’s where you
should look.
Typical lifetime cost-split for
a groundwater installation
Simple calculations will demonstrate
that increased pump efficiency
trans-lates into major, long-term
savings. Example: Pumping 450 gpm
at a head of 250 ft over 10 years,
operating 8 hours a day at an energy
cost of $0.10/kWh – a savings of
approximately $12,000 can
be achieved by choosing a
pump with a 10% higher
efficiency rate.
Initial cost 5%
Maintenance cost 10%
Energy cost 85%

There’s more to it
than meets the eye…
Cost of Ownership is about thinking ahead and knowing
what lies beneath the surface – maintenance costs, energy
costs, and the benefits of having a business relationship with
Grundfos.
Maximum reliability
Reliability is an important overall parameter in system Erosion and corrosion of a pump mean loss of material and,
operations – and thus in Cost of Ownership assessment. consequently, a drop in performance and efficiency of the pump.
Grundfos pumps, motors and control systems are designed In terms of Cost of Ownership, high-efficiency in a brand new
to provide maximum reliability under all operating pump is useless if the efficiency starts to drop the moment the
conditions. This eliminates costly unscheduled shutdowns pump is brought into operation. Grundfos pumps are made
and ensures trouble-free operation at all times. from high-grade stainless steel, which ensures high efficiency
and low energy costs during the entire lifetime of a pump.
Keeping up performance
Made primarily of stainless steel components, the
Grundfos submersible range offers resistance to
abrasives and corrosive agents in the pumped water.
Contributing to this are features such as octagonal
bearings and built-in sand shields, which ensure that
particles are removed from the pump and motor by the
water itself.
Grundfos WinCAPS contains complete information about all Grundfos
pumps, including performance curves, drawings and installation and service
information. An optimisation feature in WinCAPS enables you to fine-tune
each important part in your pumping system and to find the most effective
way of operation. Using the dimensioning features of the program, we help
you to illustrate the consequences of changing parameters in the system or
in the mode of operation.

grundfos Submersibles
6, 8 and 10-Inch Submersibles
Grundfos large submersible pumps are designed to reduce operating costs
and improve efficiencies. The new high efficiency line is designed to deliver
during periods of high demand with better efficiencies and fewer losses, to
reduce your overall “cost of ownership”.
Built with the same high-quality, corrosion-resistant stainless steel
components as other Grundfos groundwater products, these pumps feature
a state-of-the-art impeller design which allows for outstanding performance
at depths over 2000 feet.
Grundfos 6”, 8” and 10” submersibles are supplied with a rugged Grundfos
submersible motor. Manufactured of stainless steel, the two units together
result in a quality pumping unit built to last.
Internal leakage caused by pres-
sure differentials within the
pump was minimized. Tests
have shown that an impeller seal
clearance gap of just 0.4 mm
between the impeller and the
chamber causes a 5% drop in ef-
ficiency. When liquid seeps out
into the pump, precious energy is wasted on circulating that
liquid. Grundfos uses a floating seal ring between chambers,
providing a nearly perfect seal.

grundfos Submersibles
3-Inch SQ Submersibles
Grundfos 3” SQ pumps combine state-of-the-art design with rugged, quality
construction. Designed to go into the same applications as standard 4” pumps,
SQ’s light weight and small size make for fast, easy installation, especially in
less-than ideal wells. With a host of advanced features, Grundfos’ 3” SQ
pumps set a new stardard for what a submersible pump should be.
By combining advanced electronics with permanent-magnet motors, we
are now able to control and communicate with pumps in ways never before
possible. Some features that come out of this combination are, Soft-Start and
integrated Dry-Run Protection.
The SQ and SQE motors are based on a permanent-magnet
rotor which produces high efficency output within a wide
load range. Other benefits include reduced heat production
and start-up torques comparable to 3-phase motors, in a
simple-to-install 2-wire format

Reliable built-in spring loaded
check valve lets you operate
the pump in any position from
vertical to horizontal.
The SQ/SQE pump design uses “floating”
impellers. Each impeller has its own
tungsten carbide/ceramic bearing. This
design and the high quality of materials
make the pump very wear resistant.

grundfos Motors and controls
More than 30 years’ experience
Grundfos has been manufacturing quality submersible motors for more
than 30 years, and Grundfos motors are rated among the very best on the
market. From 1/2 hp 3” SQ motors to 150 hp 8” MMS motors and everything
in between, Grundfos motors are designed for high efficiency, reliability, and
long operating life.
As one of the world’s leading pump producers, we know better than anyone
what is required of a reliable submersible motor. Every motor we produce
reflects the experience gained and commitment to making nothing but the
highest quality pumping systems in the world.
Low Motor Temperatures
Due to a unique thin rotor can and close rotor
to stator tolerances in the MS & MMS motors,
internal rotor losses are minimized. Large cool-
ing surfaces and internal fill fluid circulation
ensures efficient heat transfer, resulting in
cooler operating temperatures. Lower motor
temperatures mean longer lifetimes.
Surge Protection
Grundfos MS motors are capable of withstanding transients as defined by
IEEE and UL surge suppression standards. This natural immunity makes
motors resistant to damage from high voltage surges.
High thrust capacity
The Mitchell-type thrust bearings feature 4 to
6 carbon pads and a ceramic thrust runner
to ensure high thrust capacity. This type of
bearing is unique in the way that the lapping
of the rotation parts allows a quick build-up of
water film in the bearing during start up.
High efficiency, reliability, and long operating life.

Get in Complete Control
In order to get the full benefit from your Grundfos pumping system, the
system should be maintained at the ideal operating conditions. Access to reli-
able data is essential in determining the ideal range for efficiency and energy
consumption; without this data, you are out of contol.
Grundfos offers a complete range of controls for pumping systems, from
control boxes for small submersible pumps to full control units which allow
for adjustments in system settings and online monitoring. All Grundfos
controls are made to the same exacting standards and advanced design
as our pumps and motors, helping you maintain a reliable and efficient
pumping system.
With sensors installed in the well, the water table and cost per
pumped volume of water can be monitored, making it possible to
operate at the best wire to water efficiency points. Your analysis
may even tell you that it is time to pull the old pump – or the incor-
rectly selected pump – and replace it with a new high-efficiency
pump, selected based on the actual operating conditions.
Grundfos MP204 control units help protect your investment by protecting
the pump against:
• Dry running
• Overload operating against a closed valve or blocked pipe
• Insufficient flow of liquid past the motor
• Too high temperature of the pumped liquid
• Deposits on the motor
• Over- or under-voltage
• Phase asymmetry
• Onset of motor failure
• Motor overheating or burnout
With the use of a Grundfos MP204 and R100 infrared remote control, you
can monitor your pump’s operational data, including: current consumption,
voltage, running hours, power input, and fault indications.
Grundfos has a complete line
of motor control boxes, making
installation fast and easy
