Title (EN) A CENTRAL HEATING SYSTEM FLUSHING APPARATUS
(FR) APPAREIL DE RINÇAGE POUR SYSTEME DE CHAUFFAGE CENTRAL
Abstract:
(EN) A flushing apparatus (10) for internal cleaning of central heating systems and which comprises a reservoir (11) for a flushing liquid, a pump (15) for pumping flushing liquid around the system, service ports (32, 33) by which pumped liquid leaves from and returns to the reservoir (11), and a diverter valve (35) which changes the direction of flow between service ports (32, 33). The pump (15) is fully located within the reservoir for immersion in the liquid being pumped so that the pump motor is cooled by the pumped liquid.
(FR) L'invention concerne un appareil de rinçage (10) destiné à nettoyer l'intérieur de systèmes de chauffage central et comprenant un réservoir (11) contenant un liquide de rinçage, une pompe (15) servant à pomper le liquide de rinçage autour du système, des orifices de service (32, 33) que traverse le liquide de rinçage en direction ou en provenance du réservoir (11) et une vanne de dérivation (35) qui change le sens d'écoulement entre les orifices de service (32, 33). La pompe (15), entièrement logée dans le réservoir, est immergée dans le liquide à pomper de manière que le moteur de la pompe soit refroidi par le liquide pompé.
