Gianneschi centrifugal pump CB 22-120 – 230 V 1~ 50/60 Hz – 0.75 kW

Supplier code: 01CB22G122 – SKU: GIA000000513

La Gianneschi CB 22-120 is a centrifugal electric pump of the CB, designed for lifting and circulating freshwater or seawater in sanitary, air conditioning, heating, cooling systems and onboard water systems.
It is a solution suitable for continuous services where high lifts with medium prevalences, are required, according to the manufacturer's specifications.

This version is configured for 230 V – 50/60 Hz – single phase, with power consumption 0.75 kW and motor 2 poles (2800–2900 rpm).

Construction features (CB series – verified data)

• Pump body: bronze (cast iron on request)
• Impeller: bronze or special brass alloy
• Shaft: AISI 316 stainless steel
• Mechanical seal: ceramic / graphite / stainless steel
• Motor: class F insulation – IP44/55 protections (AC)
• Available voltages for the series: 1~230 V or 3~230/400 V – 50/60 Hz

The CB series is not self-priming: the manufacturer indicates that the pump must be installed below the liquid level to prevent the pump body from emptying.
