AC Drain Pump CasseteType

Description

Ceiling Cassette Air Conditioner Internal Drain Pump (PSB-12 / PLD-12 Series)Keep your climate control system running efficiently and protect your interiors from water damage with this professional-grade, built-in air conditioner condensate drain pump. Because ceiling cassette mini-split units are mounted flush against the ceiling, they cannot rely on standard gravity to shed water. This specialized internal motorized pump actively lifts and expels the heavy moisture (condensate) that accumulates on the cooling coils during standard AC operation.If your cassette AC unit is leaking water directly from the ceiling panel, throwing a water level sensor error code (such as error code “OF” or “E6” depending on the brand), or shutting down completely mid-cycle, a failing or clogged internal drain pump motor is typically the root cause.Key FeaturesBrushless Motor Architecture: Built with an advanced brushless water pump motor to guarantee ultra-quiet, frictionless operation and an extended commercial-grade lifespan.Optimized Lift Head: Engineered to reliably lift water up into the ceiling plenum and out to your primary external drainage line without backflow.Low Power / High Efficiency: Operates at an efficient $9text{W to }9.6text{W}$ profile on standard $220text{V–240V / 50Hz–60Hz}$ power leads.Integrated Mount Configuration: Features factory-molded bracket ears and a standard barbed drainage outlet designed to fit seamlessly over factory-installed rubber isolation dampeners inside the AC drain pan.Supported AC Machines & CompatibilityThis style of Built-in Central Air Conditioning Drainage Pump features a universally adopted chassis footprint. It is explicitly designed as a factory-spec replacement part for Ceiling Cassette (4-Way & 2-Way) Air Conditioners spanning from 1.5 HP to 5 HP (18,000 BTU to 48,000 BTU) capacities.It serves as a direct or highly compatible replacement part for the following major brands and model lineages featured on regional service networks:Daikin: Highly compatible with Daikin Ceiling Cassette Series built-in drainage systems.LG: Fits standard LG Cassette AC Systems utilizing internal sub-pans.Midea & Carrier: Replaces standard factory setups across commercial inverter cassette modules.Star Aire & York: Direct fitment for models utilizing the widely distributed PSB-12 4-Way 9.6W Drainage Pump and PSB-7 Series Lift Assemblies.Cross-Reference Manufacturer Codes: PLD-12 Ceiling Refrigeration Assemblies, MP-30700 Condensate Series, and Zhejiang Zhongbao auto-control component platforms.💡 Tech Tip: When replacing an internal AC drain pump, always inspect the clear vinyl drain hose and the adjacent float switch assembly. Detergent mold or dust sludge can easily clog the small impeller chamber; clearing out the sub-pan debris entirely before plugging in the new pump will prevent immediate blockages.
