Because the SOLO² drive continuously varies motor frequency from 30 to 60 Hz to hold a constant discharge pressure, this kit does not run at one fixed duty point -- across its frequency range the 18GS50 water end covers a performance envelope bounded by a maximum shut-off head of 960 ft at 0 GPM, a manufacturer-rated best-efficiency point of 18 GPM at 712 ft TDH, and a maximum runout of 28 GPM at 365 ft TDH, with the actual operating point set automatically by well depth and system demand. The controller ships factory preset to 60 PSI discharge pressure, field-adjustable to higher settings.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower:\u003c\/strong\u003e 5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Three Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 230V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Range:\u003c\/strong\u003e 30-60 Hz (VFD, variable duty point)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater End Model:\u003c\/strong\u003e 18GS50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Model:\u003c\/strong\u003e M50432\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eController Model:\u003c\/strong\u003e 3AS50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShut-Off Head (0 GPM):\u003c\/strong\u003e 960 ft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBest-Efficiency Point (mfr. rated):\u003c\/strong\u003e 18 GPM at 712 ft TDH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Runout:\u003c\/strong\u003e 28 GPM at 365 ft TDH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Output:\u003c\/strong\u003e 3.7 kW\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Load Amps:\u003c\/strong\u003e 15.7 A (4925 W)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Factor Amps:\u003c\/strong\u003e 17.5 A (5650 W), SF 1.15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocked Rotor Amps:\u003c\/strong\u003e 93 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLine-to-Line Resistance:\u003c\/strong\u003e 0.85-1.25 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Circuit Breaker:\u003c\/strong\u003e 40 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Generator Size:\u003c\/strong\u003e 13300 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eController Dimensions:\u003c\/strong\u003e Height 21\", Width 13\", Depth 8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Shipping Weight:\u003c\/strong\u003e 107 lbs (2 cartons -- motor ships separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Pressure Tank (order separately):\u003c\/strong\u003e 8.2 gal total volume (V25P or TP25P)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eConstruction \u0026amp; Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater End Bearings:\u003c\/strong\u003e Guardian bearing system with field-proven floating stack design for sand and abrasive handling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eController Interface:\u003c\/strong\u003e Aquavar SOLO² user interface board with switch connection for optional pressure or level switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDry-Run Protection:\u003c\/strong\u003e Dry well sensitivity switch and low pressure cut-off protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestart Behavior:\u003c\/strong\u003e 5 or 20 PSI pressure-drop restart switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurge Protection:\u003c\/strong\u003e Transducer protected from transient power surges; current limit settings matched to Goulds Water Technology motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Standard three-wire control box: L1, L2, and Ground in from power supply; Red, Yellow, Black, and Ground out to motor.
