Grundfos 3" SQE Series 5 GPM 3/4 HP 230volt, 2 Wire, Deep Well Stainless Steel Submersible Pump

SQE Complete 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. The 3" diameter is ideal for 4" wells and 6" wells with liners, light weight and easy to install.

 The SQE Series pumps are equipped with:

• Soft start – prevents water hammer and motor overheating
• Dry run protection – pumps are water lubricated and if your well runs low, an unprotected pump will fail
• Overload protection – if a pump becomes clogged with debris like sand or grass, it can destroy an unprotected motor
• Over and undervoltage protection – the lifetimes of unprotected motors can be greatly reduced by improper voltages. Rural parts of the country are notorious for wide variations in voltage supply
• Warranty 2 Years

Sizing an SQE Pump for your well.

This is a very important step and is something we can help you with. If you are sizing this yourself I highly recomend watching a Grunfos production on sizing. Its short to the point and you cant go wrong if you follow the guide. There are also other grundfos literachure that has been produced for this and we will have links to all of this great publications below. Used pumps are not reurnable unless they are coming in under warranty, so lets get the sizing right from the start.

First Download this booklet on the SQE pumps

*The SQE Series of pumps were made to work with the Grundfos CU301 controller to gain all of its benifits and features. This items is sold separeatley and is found by clicking on the related prodyucts tab or in our pump controls section.

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.
