Sulzer - Submersible Recirculation Pump (RCP)

The Submersible Recirculation Pump (RCP) is engineered for efficient pumping and recirculation of activated sludge in the denitrification and nitrification processes of wastewater treatment plants. This compact, easy-to-handle pump is designed for large flows and low heads, eliminating the need for costly tank structures such as inflow chambers and large rising pipes. Key features include a self-cleaning propeller, optional full stainless steel construction, a silicon carbide mechanical seal with a solid deflection ring, and condition monitoring for temperature and water ingress. The RCP offers high efficiency, reliability, and a long bearing lifetime, making it ideal for demanding wastewater applications.
