Main Applications
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•Anyotherhighflow,highheadapplication
HPDMpumpscombinehighefficiency,highreliabilityandsturdiness,areeasytoinstall,operate and maintain and are famous for their longevity.
