Energy Savings
  • Permanent split capacitor (PSC) motor and dual ball bearings
    allow for lower amp draw
  • ST Series will save on average of $57 per year (assumes industry average of 9.5 amps for ⅓ HP pumps and 10.5 amps for ½HP pumps, $0.12 per kilowatt hour and running time of 5 minutes per hour)
  • Pump will pay for itself in just a few years
  • The ST1033 pumps 6.1 gallons per watt hour (G/Wh) used, which is 172% more efficient than the competitive average of 1/3 HP sump pumps.
  • The ST1050 pumps 7.5 gallons per watt hour (G/Wh) used, which is 138% more efficient than the competitive average of 1/2 HP sump pumps.
