Overview of Calpeda 0.75 HP Submersible Borehole Pump 4SDX 3/9C

The Calpeda 0.75 HP Submersible Borehole Pump 4SDX 3/9C is designed for borehole installations that require a balanced combination of flow rate (of up to 70 l/min) and delivery head reaching 57 meters. Powered by a 0.55 kW (0.75 HP) motor running at 2900 rpm, this pump delivers a maximum head of 57 meters while maintaining a high flow rate of up to 70 l/min. It is suitable for continuous submerged operation in clean water applications with a maximum liquid temperature of 35°C and sand content up to 50 g/m³. The pump is equipped with a 2-pole motor, insulation class F, and IP68 protection, ensuring safe and stable operation in submerged conditions. Operating at 50 Hz, it supports both single-phase 230 V and three-phase 230–400 V power supplies, allowing flexibility during installation. This model is commonly used for domestic water supply, irrigation systems, and small commercial boreholes where consistent flow and moderate pressure are required. Available configurations:
