特征及优点 / Features and Benefits主要应用
HPDMs are tailor-made axially split volute pumps extensively used to transport large volumes of liquid over long distances and high geodetic heights. They are mainly used in:• Water transport• Transport of crude oil• Any other high flow, high head application
HPDM pumps combine high efficiency, high reliability and sturdiness, are easy to install, operate and maintain and are famous for their longevity.
