NH high head slurry pump
Type NH pumps are single- stage, sing le-suct ion, cantilevered, double casing,horizonta I, centrifugal s lurry pump. They are designed for conveying strong abrasive slurries in the mining, metallurgicaI, power, chemicaI, papermaking building material industry etc. This series of pump is suitable for low flow, high concentration and high head working condition, especially suitable for the high head working condition that single- -stage pump can't delievery.
