The innovation will enable reduced submergence leading to reduced excavation cost to the customer

November 2021: Kirloskar Brothers Limited (KBL) has successfully received a patent for its Concrete Volute Pumping (CVP) Assembly. This patent is a significant milestone as it will help the company offer its concrete volute pumps with reduced submergence leading to reduced excavation cost to the customer. The patent will further consolidate KBL as a leader in the designing and manufacturing of concrete volute pumps worldwide.

KBL has designed and constructed CVPs for many large irrigation and powers projects, stormwater applications, including Sardar Sarovar Narmada Nigam Ltd, Reliance Energy Ltd, National Thermal Power Corporation (NTPC), Nuclear Power Corporation of India (NPCIL), BMA Thailand.

The concrete volute pump was a revolutionary development in the pump industry. Concrete Volute Pumps derive their name as the casting and suction draft tube is concrete, while the rotating parts are metallic. As the casing is constructed in concrete at the site, CVP is the most suitable pumping option from techno-economic consideration for handling large volumes of water. Concrete volute pumps guarantee strength and rigidity and virtually eliminate the problems of corrosion and erosion. It also ensures higher and consistent pump efficiencies over a sustained period of operation. Due to the simplicity of construction and ease of maintenance, the reliability achieved is 99.95%.
