Reduced Mechanical Noise: Precision-balanced internal components minimize resonance through the ductwork or unit chassis

you should never downsize the voltage rating

reducing the risk of premature failure during peak summer loads

the 163892 provides a direct drop-in fit

Key Benefits OEM Compatibility: Direct replacement pump for PUM2011 and PUM3011

Belimo F6125HDU Valve Assembly Refrigerant Reduced Mechanical Noise: Precision-balanced internalThe Belimo F6125HDU is a professional grade 5 inch 2 way butterfly valve designed for high capacity flow control in commercial hydronic systems. This ductile iron butterfly valve features a 304 stainless steel disc and an EPDM liner, ensuring bubble tight shut off and zero leakage up to a 50 PSI close off pressure. With a high flow coefficient (Cv 1022), it is optimized for chilled water, hot water, and up to 60% glycol solutions. The F6125HDU valve
