Title (EN) FOOT FILTER EQUIPPED WITH PVDF PLASTIC SPRING, USED AS ACCESSORY FOR ELECTRO-MECHANICAL PUMPS
(FR) FILTRE INFÉRIEUR ÉQUIPÉ D'UN RESSORT EN PLASTIQUE PVDF EMPLOYÉ COMME ACCESSOIRE DE POMPES ÉLECTROMÉCANIQUES
Abstract: front page image
(EN)A bottom filter (H) for metering pumps comprises a one-way valve equipped with a thrust spring (M) made of plastic material that is highly resistant to chemical and mechanical attack, such as for example PVDF, appropriately installed in contrast with a ball (S) that bears upon a purposely provided sealing seat towards which it is pressed by the spring (M) itself.
(FR)L'invention concerne un filtre inférieur (H) pour des pompes doseuses (F), caractérisé en ce qu'il comporte une valve de non-retour pourvue d'un ressort de poussée (M) réalisé dans une matière plastique hautement résistante à l'attaque chimique et mécanique, par exemple en PVDF, installé de façon appropriée face à une sphère (S) s'appuyant sur un joint d'étanchéité adapté contre lequel la sphère est comprimée par le ressort (M).
