Zero-Priming Underwater Design: Operates fully submerged inside open wells, sumps, and reservoirs, eliminating foot valves, suction pipe leaks, and tedious manual priming.
Potable Water-Cooled Motor: Incorporates an eco-friendly, clean-water-filled motor design for active internal thermal regulation and prevention of winding burnouts during long duty cycles.
Cathodic Electro Deposition (CED) Coating: Cast iron components are treated with CED anti-corrosion coating to provide superior rust resistance and extended underwater durability.
Wide Voltage Three-Phase Operation (200V–440V): Engineered with a resilient wide-voltage winding structure that resists electrical surges and prevents low-voltage motor stalling.
Heavy-Duty High-Head & High-Flow Output: Delivers high volumetric discharge rates up to 110 $m^3/hr$ and total dynamic head reach up to 76 meters across demanding installations in Nepal.
