SQ/SQE Submersible Pumps
SQ/SQE pumps are suitable for both continuous and
intermittent operation for a variety of applications:
· Domestic water supply
· Small waterworks
· Irrigation
· Tank applications
SQ, SQE pumps offer the following features:
· Dry-Run protection
· High efficiency pump and motor
· Excellent wear resistance, and sand handling
capabilities
· Protection against up-thrust
· Soft-start
· Over-voltage and under-voltage protection
· Overload protection
· Over-temperature protection
· High starting torque
Additionally, the SQE pumps offer:
· Constant pressure control
· Variable speed
· Electronic control and communication
The SQ and SQE pump models incorporate a totally new
motor design. With the use of permanent-magnet technol-
ogy within the motor, the SQ/SQE pumps deliver un-
matched performance. By combining permanent-magnet
motors and Grundfos’s own micro frequency converter, we
are now able to control and communicate with the pump in
ways never before possible. A few of the features that
come out this combination are Constant Pressure Control,
Soft-Start, and integrated Dry-Run protection. These are
just a few of the many features that the SQ/SQE pumps
can offer.
The SQ pump models are a simple pump that operates at
a constant speed much like today’s conventional pumps.
The difference between it and todays' pumps is you get all
the benefits of an electronically controlled permanent -
magnet motor that cannot be accomplished with a con-
ventional induction motor. The SQ pumps are available
for single phase power.They use a simple 2-wire design
making installation easy.
The SQE uses the Grundfos “Smart Motor”. Like the SQ
model, we still use the high efficiency permanent magnet
motor, but we give this motor the ability to communicate.
The “Smart Motor” communicates via the CU300 status
box through the power leads. It is not necessary to run
any additional wires down the well. By being able to
communicate with the pump you can have Constant
Pressure Control and the ability to change the pump
performance while the pump is installed in the well. Like
the SQ motor, this is also a 2-wire motor designed for
single-phase operation.
The CU300 status box also allows you to communicate
with the "Smart Motor" with the R100 infrared remote
control. The R100 gives you the ability to monitor and
setup your pumping system to meet the specific needs of
your application.It is also important to note the “Smart
Motor" can operate without the CU300, but you will loose
some of the functions that are only possible by using the
CU300.
The CU300 provides full control of the SQE pumps. If the
pump stops, the CU300 will illuminate a light on the front
panel. If you have an R100 you will be able to trouble
shoot the system and recall the last five causes of failure.

Dry-Run Protection
The SQ and SQE incorporate integrated Dry-Run protec-
tion. When the water level falls below the inlet of the pump
the pump will shut off. After a period of time, the pump will
then automatically start up again.
For the SQ pumps the cut-off level is factory-set. For the
SQE pumps you must set this level by using a CU300 and
R100.
High Motor Efficiency
The SQ and SQE motors are based on a permanent
magnet rotor which produce high efficiency within a wide
load range.The high and flat efficiency curve of the
Permanent-Magnet motor allows for a coverage of a wide
power range with the same motor, as compared to con-
ventional AC motors. For SQE pumps, this means three
motors to cover the horsepower range from 1/3 to 1.5Hp.
High Pump Efficiency
The pump components are made from a 30% glass filled
engineered composite. The pumps are designed to
deliver at peak efficiency levels. Because of high pump
efficiencies, overall power consumption will be reduced.
Excellent Wear Resistance
The SQ/SQE pump design uses “floating” impellers. Each
impeller has its own tungsten carbide/ceramic bearing.
This design and the high quality materials make the pump
very wear resistant especially in sandy conditions.

Protection against up-thrust
During start-up many pumps start in an up-thrust condi-
tion. To prevent damage caused by up-thrust a top
bearing has been placed in the motor to protect both the
pump and the motor against up-thrust.
Soft-Start
Both the SQ and SQE motors have a soft start because of
the integrated electronics. Soft start reduces the starting
current and gives the pump a smooth and steady accel-
eration.
The soft-start will reduce your chance of water hammer,
minimizes the risk of wear and prevent overloading of your
circuit during start-up.
High Starting Torque
Because of the permanent-magnet motor the SQ/SQE
pumps have excellent starting capabilities. The high
locked rotor torque produced by the PM motor provides a
starting torque that is 1.5 times greater than conventional
pump motors. Even if the voltage is low the PM motor will
still maintain a high starting torque.
Overvoltage and Undervoltage Protection
Overvoltage and undervoltage may occur at anytime
especially if you have an unstable voltage supply.
The integrated voltage protection of the SQ and SQE
motors protects the motors when the voltage falls outside
the permissible voltage range.
The 230V pump will cut out if voltage falls below 150V or
above 280V. The motor will automatically start when the
voltage is within the permissible voltage range. It is not
necessary to have additional voltage protection.
Overload Protection
When the pump load rises above the maximum amp level,
the motor will automatically compensate and reduce the
speed to maintain its maximum amp level. If the speed
drops to 65% of the nominal speed, the motor will shut off.

Overtemperature Protection
Permanent-magnet motors emit very little heat because of
their high efficiency. The SQ and SQE motors are de-
signed with an internal circulation system to effectively
cool all the internal motor components.
As extra protection, the electronic unit also has a built-in
temperature sensor. When the temperature rises too high,
the motor will shut off; when the temperature drops, the
motor will automatically restart.
Reliability
The SQ and SQE motors have been designed to with-
stand the toughest of applications and provide reliability.
Some of those features are:
· Tungsten carbide/ceramic bearings
· Thrust bearings protecting against down-thrust
· Product lifetime equal or greater than conventional AC
motors and 4"pumps
Variable Speed
The SQE “Smart Motor” enables continuous variable
speed control within 65% - 100%(7000-10700 rpm) of
motor speed. The pump can be set to operate at any duty
point in the range between 65% and 100% of the pump's
performance curve. Your pump can then be adapted to
any specific requirement. The variable speed control
requires the CU300 control unit and the R100.
To help you decide on the proper speed, we have made
available a speed calculation program called “SQE –
Speed Calculation”. This program is available as an
option.
Installation
The SQ and SQE may be installed vertically or horizon-
tally.
Note: The pump must not fall below the horizontal level in
relation to the motor.
The following features ensure simple installation of the SQ
and SQE pumps:
· Built-in spring loaded check-valve
· Light weight makes it easy to install
· Fits in 3” or larger wells
For horizontal installation, a flow sleeve is recommended
in order to:
· Ensure sufficient flow
past the motor to provide
sufficient cooling
· Prevent the unit from
being buried in sand or
mud
Service
The modular design of the pump and motor makes it easy
to repair and service. The motor lead is also replaceable.

SQ is the perfect pump for domestic water supply. The SQ is easy to sell, install and operate.
Replacement in Existing Installation
SQ and SQE pumps can be installed as replacement of a 4” submersible pump in an existing installation.
By replacing an existing 4” pump with an SQ or SQE, you not only get the most advanced pump on the market, but
you also have the ability to upgrade your system to a constant pressure system as shown on page 8.

Function and Benefits
Constant pressure can be maintained in the system to provide you with “city like” water pressure. A flow switch starts
the pump once the tap is opened. A preset pressure is maintained via the pressure sensor and the CU300. When the
flow switch detects no flow, the tank is filled with water and the pump stops.
If consumption is below 0.8 gpm, the CU300 will start the pump when the pressure is 7 psi below the set-point. The
pump will then stop when the pressure is 7 psi above the set-point.
When consumption is above 0.8 gpm, the CU300 will control the pump performance to keep the pressure within 3 psi
of the set-point.
Constant pressure control reduces pressure variations, and allows you to use a tank as small as 2 gal.Without loss of
comfort. In installations incorporating filters, pump operation will gradually adjust as the filter becomes plugged.

Menu OPERATION Set-point Setting
From the factory, the pump is
set to maximum speed, 10,700
rpm. R100 allows you to
reduce the pump speed by
changing the setpoint. The
speed can be set from 7,000 –
10,700 rpm, at 100 rpm
intervals.
The unit of the set-point is automatically changed accord-
ing to the unit of the sensor connection to sensor input
no. 1.
EXAMPLE: Sensor input no.1 is connected to a pressure
sensor using the unit feet (ft.) and the range 0 – 200.
Therefore, the set-point of display 1.1 can be set to
between 0 – 200 ft.
Menu STATUS
The displays appearing in this
menu are status displays only. You
cannot change settings in this
menu.
Accumulated Flow
