Title
(EN) ROTATIONAL METERING GASKET PUMP
(FR) POMPE ROTATIVE DE DOSAGE À JOINT D'ÉTANCHÉITÉ
Abstract
(EN) A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The sleeve receives a gasket that forms a seal between the sleeve and the housing, the gasket having an opening surrounding a side hole of the sleeve to permit fluid to pass through the side hole between a pump volume and an inlet port or outlet port of the housing.
(FR) L'invention concerne une pompe rotative destinée à un système de dosage de fluide. La pompe rotative effectue un mouvement de va-et-vient et est inversée par un signal provenant d'un commutateur de fin de course qui est dévié par un bras d'actionneur sur un manchon rotatif du système de pompe. Le manchon reçoit un joint d'étanchéité qui forme une étanchéité entre le manchon et le boîtier, le joint d'étanchéité ayant une ouverture entourant un trou latéral du manchon pour permettre au fluide de passer à travers le trou latéral entre un volume de pompe et un orifice d'entrée ou un orifice de sortie du boîtier.
