Description
D series horizontal multistage pump is a side suction (or
vertical suction), vertical delivery, ring section type centrifugal pump with
diffuser type casing. Available in various sizes, hydraulics and
material combinations, the multistage pump is suited for a wide range of site
conditions, including clear water, neutral mineral water with particles
occupied less than 1.5% and size less than 0.5mm, corrosive liquid without
solid particles etc, which temperature is 0℃- 105℃.
