Constant pressure with SmartFloTM
The Grundfos range of SmartFlo systems are complete packages, from a single supplier, designed to provide constant water pressure in any home, irrigation or small commercial application. The SmartFlo system will constantly adapt pump performance to meet the demand for water. Even if every member of a household is using water at the same time – in the shower, in the kitchen, to wash the car, and to irrigate the lawn – the SmartFlo system makes sure that the water pressure remains constant.
The SmartFlo systems in brief

The SQE pump models can operate at a constant speed much like today’s conventional pumps.The difference between it and traditional pumps is you get all the benefits of an electronically controlled permanent magnet motor that cannot be accomplished with a conventional induction motor. The SQE pumps are available for single phase power. They use a simple 2-wire design making installation easy.
The SQE uses the Grundfos “Smart Motor”, we still use the high efficiency permanent magnet motor, but we give this motor the ability to communicate. The “Smart Motor” communicates via the CU301 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. This is a 2-wire motor designed for single-phase operation.
Grundfos’ range of submersible 3" pumps SQE is recognized worldwide for its reliable performance, high energy efficiency and long product life. The SmartFlo SQE constant pressure pump was the first ever stainless steel constant pressure submersible pump – and to this day it remains the benchmark in the market.
SQE pumps cover a wide range of applications where efficient water pumping is required, including; Water supply, Pressure Boosting, Irrigation, Mining, Fountains, Reverse osmosis, Dewatering, Ground water lowering and many more.
The NEW upgraded and extended range of high-capacity SQE 3” submersible pumps which have improved octagonal discharge, cable guard attachment, wear resistance and optimized hydraulics offer increased performance and efficiency.
SQE PUMP, MOTOR AND CU301 USER INTERFACE:
SQE Pump and Motor
The SQE is the only constant pressure pump on the market fully equipped with built-in electronic controls which allow for advanced computer controlled performance and state of the art protection features including sophisticated diagnostics. The motor design is a Variable Speed Drive which electronically changes the pump speed to match demand providing you with the incredible comfort of constant pressure.
CU301 User Interface
The CU301 User Interface is the easy to use command and control computer for operating the pump in constant pressure mode. The user simply chooses the desired water pressure by pressing the UP or DOWN arrows, and the CU301 does the rest.
In order to control pressure, it must be measured. The included pressure sensor precisely measures water pressure sending its signal to the CU301. The CU301 reads this pressure signal and then electronically commands the pump to start, stop, speed up, or slow down in order to maintain constant pressure regardless of water demand. It controls the pump via power line communications by impressing high speed data messages on the pumps power supply cable. This technology is similar to that used in a home intercom or a baby monitor.
- Domestic water supply
- Light commercial
- Tank Application
- Pressure boosting
The pumps are protected against dry running. A value of pcut-out ensures cut-out of the pump in case of water shortage in the borehole, thus preventing a burnout of the motor. Pcut-out is factory-set both for the SQ and SQE pump.
Protection against upthrust
Starting up a pump with a very low counter-pressure involves the risk of the entire impeller stack being lifted. This phenomenon is called upthrust. Upthrust may cause breakdown of both pump and motor. The motors are fitted with an upthrust bearing protecting both pump and motor against upthrust and thus preventing breakdown during the critical start-up phase.
Excellent starting capabilities
The integrated electronic unit of the motor features soft starting. Soft starting reduces the starting current and thus gives the pump a smooth and steady acceleration. The soft starter minimises the risk of wear of the pump and prevents overloading of the mains during start-up. The excellent starting capabilities are a result of the high locked-rotor torque of the permanent-magnet motor together with the few pump stages. The high starting reliability also applies in case of low voltage supply.
High pump efficiency
The hydraulic pump components are polyamide-reinforced with 30 % glass fibre.
The hydraulic design ensures high pump efficiency meaning low energy consumption and thus low energy costs.
High motor efficiency
The motors are designed according to the permanent-magnet principle (PM motor) featuring high efficiency within a wide performance range.
Over-voltage and under-voltage protection
Overvoltage and undervoltage may occur in case of unstable voltage supply. The integrated protection of all motors prevents damage to the motor in case the voltage moves outside the permissible voltage range. The pump will be cut out if the voltage falls below 150 V or rises above 315 V. The motor is automatically cut in again when the voltage is again within the permissible voltage range. Therefore no extra protection relay is required.
If the pump is exposed to heavy load, the current consumption will rise. The motor will automatically compensate for this by reducing the speed. If the speed falls below 3000 min-1, the motor will be cut out. If the rotor is being prevented from rotating, this will automatically be detected and the power supply will be cut out. Consequently, no extra motor protection is required.
The pump impellers are not fastened to the shaft ("floating"). Each impeller has its own tungsten carbide/ceramic bearing. The design and the materials chosen ensure high wear resistance to sand and thus long product life.
Over temperature protection
A permanent-magnet motor gives off very little heat to its surroundings. In combination with an efficient internal circulation system leading the heat away from the rotor, stator and bearings, this ensures optimum operating conditions for the motor. As an extra protection, the electronic unit has a built-in temperature sensor. When the temperature exceeds a critical limit, the motor is cut out. When the temperature has dropped, the motor is automatically cut in again.
The motors have been designed with a view to high reliability and have the following features:
- tungsten carbide or ceramic bearings
- thrust bearings protecting against downthrust
- product life equal to conventional AC motors.
The MSE 3 motor enables continuously variable speed control within the range from 3,000 to 10,700 min-1. The pump can be set to operate in any duty point within the 3,000 and 10,700 min-1 performance range of the pump. Consequently, the pump performance can be adapted to any specific requirement.
The variable-speed control facility requires the use of a CU 300 or CU 301 control unit and the R100 remote control.
