The UPSe 26-99 F ECM circulator pump is a high-efficiency, variable-speed wet-rotor solution for hydronic HVAC systems in residential and commercial buildings including applications like space heating, domestic hot water, space cooling, and snow melting. Compatible with gas and oil boilers as a primary pump with options for 0-10 V DC voltage or pulse width modulation (PWM) signals and 50/50 water/glycol mixture. The UPSe 26-99 also supports cold water ground loops in geothermal heat pump applications and operation in condensing environments where liquid temperature falls below ambient temperature. Delivering the best energy efficiency rating in its class, the pump offers multiple control modes (constant curve, constant pressure and proportional pressure) that optimize operation in variable flow systems, reducing energy consumption by up to 80 % compared to equivalent permanent split capacitor (PSC) circulators. A servicable design, featuring the control box and pump head as separate, replaceable spare parts, help minimize downtime and extend overall product life. An optional extension flange set is available to increase flange-to-flange installation length from 6 1/2" to 8 1/2".
