Self-Priming Pumps

For chemical liquids with high density and low boiling point

Our self-priming pumps can pump highly dense liquids without reducing performances by installing an electric motor with an increased power. They are close-coupled and the sealless versions are offering an unparalleled chemical resistance thanks to the material of construction E-CTFE.

Argal’s invention for the self-priming line consists of a turbo pump capable of priming from an empty suction pipe and with no foot valve by a biphasic operation (delivered by the special configuration of the impeller rotating within a stator casing – designed on purpose). The biphasic radial turbo pump is capable to self-prime denser liquids or vapour-tensioned liquids from a higher suction height,  in a shorter time than traditional self-priming pumps.
