SQNE 3" submersible groundwater pump - continuous and intermittent operation

Overview

Overview

SQNE is a small and compact submersible multi-stage pump designed for constant pressure operation in domestic applications. The motor of the SQNE pump is a permanent magnet motor with a micro frequency converter ensuring optimum efficiency. The built-in frequency converter features protective functions and soft-starting, which reduces starting current and gives smooth and steady acceleration and dry running protection. The SQNE pump is handy and user-friendly
due to its low weight and 3-inch diameter. For constant pressure operation, the SQE coupled the CU300 or CU301 control unit is required

Features

Constant pressure operation
Using a CU300/301 with the SQNE your water pressure will always remain constant pressure regardless of how many family members are consuming water. As more taps are opened, the pump automatically increases its speed, maintaining your chosen pressure at any flow rate. Greater comfort is added to your life and greater value added to your home.


Excellent starting capabilities
The soft starter minimises the risk of wear on the pump and prevents overloading of the mains during start-up. Its softstart system also reduces water hammering, light flickering and other electrical disturbances.


Overvoltage and undervoltage protection
The integrated protection prevents damage to the motor in case the supply voltage moves outside the permissible voltage range.


Overload protection
The SQNE eliminates the need for motor protection. If the pump is exposed to heavy load the motor will automatically reduce its speed, or if the pump is blocked it automatically stops pumping.


Over-heating protection
As an extra protection, the electronic unit has a built-in temperature sensor. When the temperature exceeds a critical limit, the pump is stopped and when the  temperature has dropped, the pump automatically starts.


Protection against upthrust
The SQNE is fitted with an upthrust bearing protecting both pump and motor against upthrust, thus preventing breakdown during the critical start-up phase.
