Description
SQE series pumps are variable speed deep well submersible pumps which offer constant pressure control/functionality when used with CU 301 or CU 302 controls with pressure sensor. These controls allow to set a desired pressure and the pump will vary speed to match the current requirements. Such installation is much more compact, as it does not require a large well water storage tank.
SQE can also be installed as is (without the control) and will operate in a manner similar to their predecessor – SQ series, where water is pumped to and stored in a well water tank (such as Well-X-Trol) and on/off operation is controlled by a standard pressure switch (such as Square D).
Features:
- Unlike SQ series, SQE is a variable speed pump, which offers constant pressure control functionality when used with CU 301 or 302 module
- CU 301/302 control (optional, sold separately) allows adjustable constant pressure selection and remote pump set-up & diagnostics
- When used with CU 301/302 module in constant pressure mode, a much smaller well tank (2 gallons) can be used, allowing for a more compact and less expensive installation
- Rugged 304 stainless steel contruction and reliable, time-tested performance
- Easy to install – single-phase, 2-wire (+ ground) design – ideal drop-in replacement for similar models, no complex wiring
- Can be wired to a standard Square D or similar pressure switch when used with a well water storage tank (Well-X-Trol or similar)
- Much higher efficiency than conventional pumps thanks to the variable-speed, permanent magnet motor
- Superior sand wear resistance thanks to the floating impellers with tungsten carbide bearings
- Dry-running protection with auto-retry
- Unique Soft Start feature ensures a smooth acceleration, prevents overload during start-up, reduces motor wear and system stress (longer life and no water hammer)
- Overvoltage and undervoltage protection with auto cut-in (retry)
- Overload and thermal protection (overheating and freezing) with auto-retry
- Built-in check valve
