Product Description

Overview

The SRDI‑38 is a deep‑well helical rotor pump designed for dual‑source operation with an integrated controller built into the pump body. It supports both DC and AC input and is intended for wells up to 750 ft with a maximum output of 5 GPM.

Key Features

  • Helical rotor, progressive‑cavity design with a single moving part.

  • Integrated controller for efficient operation.

  • Accepts 90–400 VDC or 90–240 VAC input.

  • Power range: 250–1300 watts.

  • Pump head and motor are repairable and rebuildable by SunRotor.

  • Field‑replaceable helical rotor.

  • Integrated low‑water cutoff sensor.

  • Submersion limit: 400 ft below static water level.

  • Brushless DC motor (no brush maintenance).

  • CE Certified.

  • Maximum pumped liquid temperature: 92°F (32°C).

Dimensions & Weight

  • Height: 47.25 in (120 cm)

  • Diameter: 3.9 in (fits 4 in casing)

  • Weight: 28.2 lbs (12.8 kg)

Performance

  • Maximum depth: 750 ft producing up to 5 GPM depending on panel configuration.

  • Requires 1 in NPT outlet.

  • Pump curves vary by solar array size (1200 W or 1600 W configurations).

  • Do not exceed listed depth for each configuration to avoid damage and voiding warranty.

Warranty

  • 5‑year total warranty

    • 2 years full replacement

    • 3 years declining coverage (60%, 40%, 20%)

  • Battery‑only systems carry reduced warranty: 1 year full replacement, then 18 months declining (60%, 40%, 20%).

Notes

  • Not intended for continuous 24/7 operation.

  • SunRotor recommends higher‑wattage panel configurations for areas with fewer than 5 peak sun hours per day.
