Massive 8-Inch (200mm) High-Capacity Profile: Engineered specifically for 8-inch and larger borewells, maximizing volumetric water delivery up to 120+ $m^3/hr$ for large-scale operations.
Corrosion-Proof Heavy-Gauge Construction: Fabricated with AISI 304/316 stainless steel casings, heavy cast iron/stainless suction and delivery casings, and an AISI 431/304 shaft for long underwater service life.
Extreme 400+ Meter Multi-Stage Head Lift: Multi-stage hydraulic stacking delivers massive pressure capability reaching up to 400+ meters for deep-aquifer extraction and high-elevation boosting.
Sand-Handling Impeller Architecture: Precision-engineered bronze, stainless steel, or high-strength Noryl mixed-flow and radial impellers handle abrasive suspended sand particles smoothly to prevent seizing.
Oversized Thrust Bearing & Built-in NRV: Integrated with a heavy-duty thrust bearing assembly to manage severe downward hydraulic loads and an internal non-return valve to eliminate backflow shocks across installations in Nepal.
