Engineered for customers who demand extra power and durability, Rainbow Pumps’ V-4 Powerful Norly Radial-Flow Submersible Pumpset delivers robust discharge while keeping energy use in check. Designed for 100 mm (4 inch) borewells and deeper, the pump’s hydraulics use high-strength Noryl™ impellers and diffusers that resist abrasion, scaling, and corrosion. A stainless-steel motor casing, dynamically balanced rotor, and heavy-duty thrust bearing ensure smooth, vibration-free performance even under challenging voltage conditions. Whether you’re irrigating fields, supplying multi-storey buildings, or running process water lines, this pumpset gives you reliable, high-volume water transfer day after day.
Key Features :-
-
High-Head, High-Discharge Output – Optimized radial-flow design paired with Noryl impellers delivers a strong, steady flow with exceptional hydraulic efficiency.
-
Noryl™ Impellers & Diffusers – Tough, lightweight thermoplastic resists wear from sand particles and aggressive water, extending pump life.
-
Stainless-Steel Build – Motor body, shaft, and pump sleeve in SS-304 for superior corrosion resistance.
-
Wide-Voltage Compatibility – Starts and runs smoothly across broad voltage fluctuations (160 V – 240 V single-phase / 280 V – 440 V three-phase).
-
Heavy-Duty Thrust Bearing – Handles axial loads for continuous, maintenance-free operation.
-
Integrated Non-Return Valve (NRV) – Prevents back-flow, safeguarding the system against water hammer.
-
Low Noise & Vibration – Dynamically balanced rotor and precisely machined components keep operation whisper-quiet.
-
Thermal Overload Protection – Optional embedded protector shields the motor from overheating and dry-run conditions.
