Abstract

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.
