Import 3`` (80 Mm) And 4`` (100 Mm) Submersible Pump — Buy in Bulk from Supplier in India

The 3" (80 mm) and 4" (100 mm) submersible pumps from Waterman Industries are multi-stage centrifugal pumps with radial or mixed-flow impellers, designed for submerged operation in wells, boreholes, or open water sources. These pumps are driven by wet-type, water-lubricated motors that function effectively under low voltage conditions, making them suitable for rural or unstable power supply environments. The range includes models from 0.5 HP to 1.5 HP, with heads spanning 9 to 120 metres and flow capacities of 10 to 95 litres per minute.

Constructed with durable materials, the pump’s motor body uses stainless steel with 1% nickel, while the stator features electrical-grade silicon steel sheets with a watt loss of 3.9 to 4.5 W/hour. Key components include a stainless steel 304 tilting pad thrust bearing, GM LTB-4 bush bearing, and a stainless steel 420 heat-treated rotor shaft. The pump assembly incorporates graded cast iron (G20) for suction and non-return valves (NRV), Noryl-glass-filled impellers with stainless steel neck rings, and a stainless steel 410 pump sleeve with hard chrome plating.

These pumps are ideal for agricultural irrigation, domestic water supply, and industrial applications requiring reliable submersible performance. Typical buyers include farmers, municipal water projects, and construction firms. The pumps operate at 2900 RPM with a voltage range of AC 180-240V, 50 Hz, and the supplier offers 25 distinct models to cater to varying head and flow requirements.
