Open Impeller Pulp Pump-ESK

Description

The ESK series open-impeller pulp pump is a technologically advanced design developed through years of experience and incorporating both domestic and international innovations. It is highly efficient for handling fiber, mud, and paper pulp with a consistency of up to 5%, as well as liquids with up to 30% solid content. The pump is suitable for a wide range of industries, including papermaking, metallurgy, salt collection, drainage, and power plants. Its casing features an end-suction and radial discharge design, with the discharge centerline and shaft aligned in the same vertical plane, all securely fixed on a robust base plate. The front and back wear plates are designed with a modular structure to allow easy replacement when wear occurs, ensuring efficient performance and prolonged lifespan.
