Designed as multi-stage centrifugal pumps with closed radial or mixed flow impellers, these pumps operate in a vertical position with a water-filled, water-cooled motor. The impeller accelerates the liquid, converting kinetic energy into pressure through the diffuser, ensuring high efficiency and stable performance even under challenging conditions.

The BSP series of Borewell Submersible Pumps is ideal for deep mines and heavy-duty applications. Each pump unit combines a water-filled submersible motor with a multi-stage centrifugal pump installed in a suction hood, providing safe, reliable, and low-maintenance operation. Unlike traditional deep well pumps, SB Borewell Pumps operate quietly with minimal vibration and eliminate the risk of electric sparks, making them suitable for areas with potential gas hazards. The motor features poly-insulated winding wires and a pressure compensation device at the base to maintain optimal performance under varying pressure conditions.

SB Borewell Pumps are capable of delivering heads up to 400 meters with flow rates up to 1000 m³/hr and operate at 2900 RPM. They are compatible with a wide range of voltages (380V, 415V, 550V) and can handle clear water, sea water, and other applications requiring durable submersible pumping solutions. Materials of construction are selected to suit specific environments, including Cast Iron, SS304 (CF8), SS316 (CF8M), SS316L (CF3), and Bronze, ensuring corrosion resistance, abrasion resistance, and long service life.
