Material: Cast iron, Cast steel, Stainless steelSize: 1-1/2"~12", DN40mm~DN300mmFlow Rate (Q) 3.75 - 840 (m3/h)Lift Head (H) 19 - 680 (m)Multistage pump is a kind of centrifugal pump, and rely on the rotation of the impeller in the centrifugal force, and material. For gas density to achieve the mechanical vacuum pump was out working range, and thus gradually obtain high vacuum. Multistage pump can be used in petroleum, chemical, machinery, mining, light industry, medicine and food and many other industrial sectors. In many industrial production process, such as vacuum filter, vacuum water diversion, vacuum feed, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing, multistage pump has been widely used. Multistage pump refers to two or more than two impeller pump.
