Centrifugal pump KC series

for liquidswith asynchronous motorstationary

Overview
The KC series close-coupled centrifugal pumps with a single impeller (1"1/2) are engineered for transfer of clear liquids without abrasives or suspended solids. Suitable for non-explosive, non-aggressive fluids compatible with the pump materials.

Applications

• Domestic water distribution and recycling systems
• Integration in industrial machines
• Small-scale irrigation
• Water recirculation in process systems
• Tank filling and accumulation systems

Performance

• Liquid temperature: up to 35 °C for domestic use (CEI EN 60335-2-41), up to 90 °C for other uses
• Maximum ambient temperature: 40 °C
• Flow rate: up to ~21 m3/h
• Maximum head: up to ~35 m

Technical features

• Pump body: cast iron G20 with anti-corrosive coating
• Motor bracket: cast iron G20 with anti-corrosive coating
• Impeller: stamped brass (UNI-EN 12165)
• Shaft: stainless steel AISI 304
• Mechanical seal: carbon-ceramics

Motor
The drive motors are asynchronous squirrel-cage type, closed with external ventilation.

• Single-phase models: built-in motor protection and permanently connected capacitor
• Three-phase models: motor protection to be provided/installed by the customer (use equipment compliant with applicable standards)
• Insulation class: F; Duty: S1; Degree of protection (motor): IP44
• Terminal board protection: IP54
