Deep well pumps 3" B-SP

Deep well pumps 3" B-SP

The 3” deep well pump type B-SP is made entirely of stainless steel and is characterized by high durability and reliability. With a diameter of 75 mm, these pumps are suitable for boreholes and wells from a diameter of 110 mm.

Category: Water supply

The 3” deep well pump B-SP is a compact, high-performance stainless steel submersible pump designed for reliable water extraction from deep wells, boreholes, and cisterns. With a slim outer diameter of 75 mm, the pump is suitable for installation in wells from 110 mm diameter, making it ideal for confined installation conditions.

Thanks to its maximum delivery head of up to 105 m, the B-SP can be operated flexibly with pressure tanks and pressure switches or in combination with a frequency converter for demand-controlled operation. Its robust stainless steel construction ensures long service life, high operational reliability, and excellent corrosion resistance — even in demanding water conditions.

Designed for continuous and industrial use

All hydraulic and mechanical components of the B-SP are manufactured entirely from stainless steel, ensuring high resistance to corrosion, abrasion, and mechanical stress. This makes the pump suitable for continuous operation in both drinking water and industrial process water applications.

The pump reliably conveys clean water and slightly contaminated water with a sand content of up to 150 g/m³, making it suitable for a wide range of practical applications in agriculture, industry, and infrastructure.
