Holdwell S 3HP Deep Well Pump – 4″ Stainless Steel, 37GPM, 640ft Head

A high-performance 3HP (2200W) submersible pump from Holdwell S delivers powerful water extraction for industrial, irrigation, and residential needs. Powered by a 230V/60Hz copper motor with F-class insulation and built-in overheat protection, this 4-inch stainless steel pump features 16-stage thermoplastic impellers for reliable, long-term operation. With a 37GPM (140L/min) flow rate and a 640ft (195m) max head, it efficiently handles deep well extraction, farm irrigation, and heavy-duty water lifting tasks.

The pump’s durable stainless steel construction ensures corrosion resistance in harsh underwater conditions, while its IP68 waterproof rating protects against deep submersion. The external controller features an IP44 rating, guaranteeing stable performance even in wet environments. A 33ft electric cord and 1-1/4″ NPT stainless steel discharge provide flexibility for installation in wells with 4-inch or larger casings. Built-in overheat protection prevents burnout during stalling or abnormal conditions, ensuring safe operation.

For optimal performance, the pump includes a check valve to prevent backflow (an additional check valve is recommended for enhanced protection). A stainless steel filtration mesh blocks debris, while gauze can be added at the inlet for wells with excess sediment. This versatile pump is ideal for residential water supply, livestock watering, pond filling, and industrial applications.
