Performance Range
    Capcity(Q): max.7000m3/h
    Head(H): max. 25m
    Operating Pressure(P):max.0.6MPa
    Operating Temperature(T):max.-20~+120

Application Ranges
    Compulsory circulating in chemical processing
    Seawater breed aquatics
    Water handling system
    Generally, this series pumps can economically and effectively transfer high capacity, low head, homogeneously liquid or slightly polluted materials in it, neutral chemical or corrosive liquid.

Feature
    High pump efficiency, low energy consumption.
    Pump can evenly consume energy within all performances. Pump can be started when the valve is closed, and the motor does not overload.
    Large flow proportion and uneasily blocked.
    Solidity structure and long life.
