Pedrollo BC-ST Series Submersible Pumps
Powerful and resistant, high-performance submersible pumps made entirely of stainless steel.
Product Overview
The Pedrollo BC-ST submersible pumps are manufactured entirely from stainless steel, offering exceptional resistance to corrosion and abrasion. They are designed for efficient drainage of dirty and residual water in domestic, civil, and industrial applications.
Equipped with a BICANAL impeller, these pumps can handle liquids containing solids up to Ø 50 mm with short fibers. They are ideal for pumping wastewater and sewage in holiday homes, country houses, and single-family dwellings.
The hydraulic design of the volute and the BICANAL impeller, resulting from advanced fluid dynamic calculations, ensures excellent performance and high energy efficiency, leading to significant energy savings.
The BICANAL impeller provides superior performance and efficiency, generating higher pressure and allowing the pumping of solids up to 50 mm in diameter, making it a highly effective solution for wastewater drainage.
Performance Characteristics
- Flow rate: up to 850 l/min (51 m³/h)
- Head: up to 16 m
Uses and Installations
Recommended for draining dirty and residual water in domestic, civil, and industrial sectors.
Suitable for transporting wastewater, sewage, surface water, and mixed water with sludge.
