Centrifugal pump KF series

for liquidswith asynchronous motorstationary

PRODUCT OVERVIEW
The close-coupled centrifugal pumps of the KF series with a single impeller are designed to transfer clear liquids free of abrasives and suspended solids, not explosive and not aggressive to pump materials. They are suitable for domestic applications (within the applicable standard limits) and for general industrial uses within the stated temperature and ambient limits.

PERFORMANCE

• Liquid temperature: up to 35 °C for domestic use (CEI EN 60335-2-41) or up to 90 °C for other uses
• Ambient temperature: up to 40 °C
• Flow rate: up to 60 m3/h
• Head: up to approx. 18 m

CONSTRUCTION

• Pump body: Cast iron G20 with anti-corrosive coating
• Motor bracket: Cast iron G20 with anti-corrosive coating
• Impeller: Cast iron G20 with anti-corrosive coating
• Pump 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 include built-in motor protection and permanent capacitor.

• Three-phase models: motor protection must be provided by the installer (use equipment complying with applicable standards)
• Insulation class: F
• Duty: S1
• Degree of protection (motor): IP44
• Terminal board protection: IP54
