Carrier 53DS-900-064 Condensing Pump

The Carrier 53DS-900-064 Condensing Pump is a 230 VAC condensate pump accessory in the 53DS-900 family, designed for Carrier MFQ/MFC systems with 12K–24K cooling/heating capacities to automatically remove condensate from the indoor coil to an appropriate drain. The 53DS-900-064 variant is the 230‑volt option (distinct from the 53DS-900-117 115‑V version used on 9K–12K models and the 53DS-900-118 230‑V variant for 12K, 18K, 22K). Carrier literature lists this pump as compatible with cooling‑only and heat‑pump configurations, making it suitable for a range of Carrier ducted and ductless applications. When installed as part of an MFQ/MFC system, it supports continuous operation by moving condensate away from the evaporator coil to a remote drain, helping prevent water damage and service interruptions in humid environments. It is intended for use with Carrier 53DS accessories and is selected to align with the system’s capacity class (12K–24K).
