Open Impeller Pulp Pump——ESK

ESK series open-impeller pulp pump is based on new technology,the pump is successfully design
Based on long-term technology accumulation and on the experience of domestic and overseas advanced technology.
The pump has a strong capacity to transport fibre,mud,the paper pulp below 5% consistency and other liquid with below 30% solid content.It can be used in those operating environments in the paper making，metallurgy,salt collecting,drainage and power plant,etc.
The casing is end suction and radial discharge design.Its discharge centerline and shaft are in the same vertical plane.the casing is directly fixed on the base plate.
The front wear plate and back wear plate be designed for stripped down structure.we can replace worn part when the inter spacer becomes large.
