S-Drive™ Variable Speed Submersible Pump Controller

S-Drive FAQ

A variable-speed pump controller made specifically for submersible pump water well applications. Comes complete with pressure transducer and load filter for up to 1,000 feet of motor lead. Standard NEMA 3R outdoor rated enclosure.

Irrigation → Irrigation applications use both submersible and surface pumps about equally. The S-Drive can control standard 4″ and 6″ submersible motors as well as turbine pumps and surface centrifugal pumps up to 30 HP.
Rural Water → Rural water districts often pump ground water from community wells with single pumps of less than 50 HP. Many have a single water tower, which limits system pressure during peak periods or at remote ends of the distribution system. The S-Drive can automatically compensate for demand variations with either submersible or surface boosters.
Building Booster → Commercial buildings of less than ten stories may require supplemental pressure to offset what is provided by the municipal system either on a permanent basis, or during periods of peak demand.
Agriculture → Commercial farms for crops or livestock require a reliable source of irrigation, feeding or cooling water. Dairy, turkey, chicken, beef and various commercial crops all require a constant source of water with varying demands throughout the season.

Features and Benefits

  • Easy Set-up: Pre-set for submersible motor characteristics. Pre-wired and tested transducer. Touch button pressure setting. No complicated menus or electrical jargon to cope with. Total set up time including wiring is less than 30 minutes.
  • NEMA 3R: Outdoor rated enclosure eliminates the need for separate cover panels required by standard NEMA 1 enclosures.
  • Dual Phase : The same drive can be used for either three-phase or single-phase input (de-rated). Both configurations are UL/CUL approved for inventory flexibility.
  • Filter Pack: The S-Drive comes complete with output filter rated to 1000 feet of motor lead. It is ready to go without having to source and install components from other sources. Programming is also preset to 35 Hz minimum to protect motor bearing lubrication required by some motor manufacturers.
  • True Motor Match: The S-Drive is already rated for the higher amps typical of higher HP submersible pump start-up. There is no need to oversize the drive.
  • Transducer: As with all Goulds Water Technology drives, the pressure transducer is included with the drive so there is no need for separate sourcing and compatibility checks. The transducer is pre-wired and tested.
  • Full Diagnostics: In addition to typical electrical protection and diagnostics, the S-Drive has a full range of pump protection features such as bound pump or motor shut down, low water or loss of prime shut down. These added features require no added input devices.
  • Program Security: The flashing LED status indicator will not fade in outdoor use the way LCD screens do, and the internal single push button discourages tampering by untrained operating or maintenance personnel.
  • Remote on/off: Permits external control by timers (irrigation), float or pressure switches (tank draining) or manual control. Reduces the need for separate patch panels.
  • Hand/Auto Option: Allows the drive to be run full speed for longer periods of time as in the case of new well development or system start up. Turning the control back to “auto” resumes the automatic pressure tracking and control.
  • Remote Monitoring: External monitors may be connected to the drive for pump running speed (Hz), pump on, and system fault. The fault indicator can also be connected to devices like an auto-dialer. This enables control of pumps and drives in unmanned locations.
  • Pressure Drop: The reaction time of the drive to pressure drops can be adjusted from the typical 3-5 PSI drop to as much as 20 PSI. This allows for smoother transitions and fewer starts when using a supply tank.
  • Dual Set Point: The S-Drive has the capability to be programmed with two pressure set points. An external contact such as a timer can be used to change between them, so that a booster pump serving a building and an irrigation system simultaneously can do both jobs without manual resets.
