Description
Built for extreme lift applications, the SRDI-36 is SunRotor’s deep-well, positive-displacement submersible that reaches water others can’t.
Its helical-rotor (progressive-cavity) design generates high pressure at low RPM, giving early-morning starts, late-day run time, and steady flow as head increases—ideal for remote homesteads, ranch tanks, and wildlife water points where uptime matters.
An integrated controller inside the pump body accepts wide-range DC or single-phase AC, reducing wiring complexity and maximizing conversion efficiency. Stainless construction, a 4-inch-casing fit, and field-serviceable internals make it a durable, long-life choice for very deep wells.
Product Details
-
Deepest lift in the line: Delivers about 3 GPM down to 900 ft TDH with proper arraying—built for serious depth.
-
Dual-source power: Runs from 60–370 VDC PV input or single-phase AC, thanks to the integrated controller.
-
Positive-displacement hydraulics: Progressive-cavity rotor/stator provides consistent flow as head rises and resists silt/air intrusion better than centrifugal designs.
-
Serviceable & robust: Replaceable helical rotor; pump head and motor are rebuildable; brushless DC motor; integrated low-water cutoff. Installer friendly: 1" FNPT outlet, 3.9" OD to fit 4" casings, submersion limit 400 ft, and accessories like float/pressure switch kits available.
