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.
