CANTILEVER

Product catalog summary

Overview: The document provides technical specifications and operational guidelines for cantilever pumps with channel and vortex impellers, highlighting their design, materials, and installation procedures.

Specifications:

Design: Cantilever pumps are designed without submerged bearings or bushings, allowing them to handle abrasive solids without external flushing. They can operate at temperatures exceeding 500°C and run dry without damage.
Impellers: Available in vortex and channel types. Vortex impellers allow solids passage up to 90% of the discharge port size and are suitable for abrasive liquids. Channel impellers are for dirty, slightly abrasive liquids without filamentous parts.
Materials: Standard materials include cast iron and AISI 316, with options for special alloys like SAF 2205 and AISI 904L upon request.
Column Length: Ranges from 0.3 to 1.5 meters, with longer lengths available on demand.

Installation and Operation:

Installation Types: Pumps can be installed internally or externally to tanks/sumps, with or without mechanical seals. They can operate without level controls and run dry until the liquid level rises to the priming point.
Suction Depth: Capable of emptying tanks up to 5 meters deep using a tail pipe.
Temperature Handling: Standard installations handle up to 300°C, while special executions can manage up to 400°C.

Maintenance and Cost: The robust construction and absence of mechanical wear result in minimal maintenance costs, offsetting the initial purchase cost over time.

CANTILEVER L’assenza di cuscinetti o bronzine immersi consente di pompare solidi anche abrasivi senza flussaggi dall’esterno. L’assenza di tenute a contatto con il liquido permette di raggiungere temperature superiori a 500°C e di lavorare a secco senza alcun danno. La pompa si adesca automaticamente quando il liquido copre la girante per cui è in grado di lavorare anche senza controlli di livello. L’uso del tubo di aspirazione consente di svuotare vasche fino a 5 metri di profondità. Grazie ad una costruzione molto robusta e all’assenza di usura meccanica la pompa cantilever ha costi di manutenzione...
