Centrifugal pump Medana CH1-LC series

waterelectricself-priming

Product name
Medana CH1-LC

Short description
Multistage monobloc pump

Key benefits

• High efficiency thanks to high hydraulic output
• Highly reliable and robust with low noise emissions thanks to neck ring and corrosion-resistant lantern with cataphoretic coating
• Suitable for use in ambient temperatures of up to 50 °C – expanded field of application especially for system integration
• Compliant to UL certificate

Efficient system integration
Wilo-Medana CH1-LC with its robust pump housing offers high reliability and, with its corrosion-resistant components, a large field of application for integration in larger systems even at ambient temperatures of up to 50 °C. The non self-priming, multistage pump achieves maximum hydraulic output.

Product features

• Compact design for a better system integration
• Cataphoretic coating
• Reinforced pump feet with closed hole for vertical fixation
