Abstract

Il filtro aspirante è previsto per una pompa sommersa, in particolare per una pompa di fontana, ed è costituito da una cassa che circonda completamente il gruppo pompa, il tubo di mandata del gruppo pompa passando attraverso questa cassa. Con questa disposizione la superficie di aspirazione del filtro risulta così aumentata da impedirne efficacemente un deterioramento. Inoltre, il gruppo pompa è protetto dal filtro contro danneggiamenti meccanici. Inoltre, il filtro funge anche da imballaggio per il gruppo pompa.The suction filter is provided for a submerged pump, in particular for a fountain pump, and consists of a case that completely surrounds the pump unit, the delivery pipe of the pump unit passing through this case. With this arrangement, the suction surface of the filter is so increased as to effectively prevent deterioration. In addition, the pump assembly is protected by the filter against mechanical damage. In addition, the filter also acts as a packing for the pump set.
