What is a flexible pump?

flexible pump is a kind of vacuum suction fluid, extruding the volume of drainage pump, has some unique features. Since the invention of more than sixty years ago, has obtained more and more widely in various industrial and mining applications.
,
flexible pump working principle (1) pump cavity with an eccentric block, when the flexible blade left the eccentric block, the blade between the increasing volume, vacuum, uninterrupted by the liquid suction pump cavity entrance.
2. When the flexible blade rotation, the liquid by the suction pump housing department was brought into eduction department.
(3) when the flexible blade in contact with the eccentric convex block again, bending, and accompanied by a squeezing action, make the liquid continuously, without pulse discharge pump cavity, so as to finish the whole course of suction line.
and flexible pump impeller of the flexible elastomer technology
as the core technology of flexible pump, pump impeller should be has good elasticity, small permanent deformation, and can withstand high frequency flexible for a long time without breaking and tearing. 'Ten years grinding sword', the remarkable elastomer technology determines the pump impeller excellent performance and durability. Now there are two types of impeller material - — Nitrile rubber, ternary 3-20 health level; Nitrile impeller is mainly used for vegetable oil, mineral oil, oil medium, and health to demand higher areas; Ethylene-propylene wheel is mainly used for weak inorganic acid, organic acid, alkali, salt, alcohol, ketone, sewage and other wide range of media.
