Product catalog summary
Overview: The document provides detailed specifications and features of the RB multi-channel centrifugal pumps, highlighting their high efficiency, low NPSH, and versatility in handling various industrial applications.
Main Features:
  • Ability to handle solid parts and high viscous liquids without clogging.
  • Low pulsation and noise levels.
  • Large suction inlet and few blades for reduced inlet speed and improved suction characteristics.
  • High efficiency comparable to closed impellers, especially with viscous liquids.
Applications:
  • Food Industry: Suitable for evaporation plants, raw juice transfer, and pasteurization up to 98°C.
  • Washing Plants: Effective for liquids with suspended solids.
  • Cooling and Condensation Plants.
  • Sugar Mills, Waste Water Treatment, Paper Mills, Chemical Industry, Steel Mills, and Textile Industry.
Modularity and Materials:
  • Four bearing housing-shaft groups for 15 sizes ranging from 65 to 300 mm discharge port size.
  • Materials include GJL250 cast iron, AISI 316, Duplex, Superduplex, AISI 304L, AISI 904L, Sanicro 28, Hastelloy B and C, CA6NM, and other alloys on demand.
Design and Maintenance:
  • Unified bearing housing for various impeller types, ensuring shaft deflection < 0.05 mm and a minimum of 18,000 operation hours.
  • Modular execution allows easy adaptation to new plant requirements.
  • Easy maintenance with only a few components needed for the entire pump range.
Sealing Systems:
  • Various seal types available, including self-lubricated, single and double mechanical seals, and cartridge seals.
  • Heating and cooling chambers can be easily installed.
Advantages of Multi-Channel Impeller:
  • Low inlet and outlet flow speeds reduce friction losses and improve efficiency.
  • Suitable for pumping liquids with suspended solids, dirty liquids, and concentrates.

GIRANTE MULTI-CANALE MULTI-CHANNEL IMPELLER ^ RB Passaggio di corpi solidi Liquidi ad alta viscosita Basso NPSH Elevato rendimento No pulsazioni - No rumore Queste sono le caratteristiche principali della gamma RB con giranti multi-canale che consentono di raggiungere elevate prestazioni anche in condizioni critiche. La grande sezione di imbocco e il basso numero di pale riducono la velocita di ingresso garantendo ottime capacity di aspirazione anche in presenza di gas e aria disciolta. Le grandi luci di passaggio e la forma delle pale riducono le velocita interne alia girante migliorando le...

GIRANTE MULTI-CANALE: Basso NPSH, basse perdite, alta efficienza MULTI-CHANNEL IMPELLER: Low NPSH, low friction losses, high efficiency VANTAGGI DELLA GIRANTE MULTICANALE: Le giranti delle pompe RB hanno velocità di imbocco e uscita molto basse (comparate ad una girante tradizionale) e rendimenti simili alla girante chiusa. Le basse velocità si traducono in basse perdite per attrito sia di imbocco che di attraversamento che a loro volta garantiscono bassi NPSH e maggior efficienza nel convogliamento di liquidi viscosi. Sono anche in grado di pompare liquidi contenenti solidi in sospensione, liquidi...
