Product Features

This Sanhua PSB-12A pump features stable voltage adaption, automatic sensor operation, wide HVAC compatibility and durable OEM-grade build quality

1. Wide voltage compatibility: Supports 220V to 240V mainstream household and commercial AC power supply, stable operation with minor grid voltage fluctuation.
2. Auto-sensing pumping mechanism: Built-in water level sensor activates pumping when condensate accumulates to a preset height; cuts off operation automatically once water is drained completely.
3. Broad equipment compatibility: Direct fit replacement for most Midea and Gree ducted central AC indoor units and wall-mounted air conditioners ranging from 1HP to 15HP.
4. OEM-standard manufacturing: Sanhua official matching spare part, precise dimensional fitting without pipe modification or extra wiring during installation.
5. Low noise & long service lifespan: Low-vibration motor design reduces operating noise during drainage; wear-resistant internal pump structure extends continuous working life.
6. Plug-and-play installation: Pre-reserved wiring terminals and drainage nozzle interface match original unit wiring and drain hose for quick DIY or technician installation.
7. Anti-overflow protection: The sensor prevents dry run and over-pumping, avoiding pump burnout and secondary water leakage issues.

Application Scenarios

HVAC technicians, property maintenance staff, home owners, commercial store managers and air conditioner after-sales repair teams are the primary users for this drain pump

1. Ceiling Ducted Central AC Renovation (Residential Villa/Apartment) Homeowners with concealed ducted central air conditioning find the original factory drain pump fails, causing ceiling water seepage. Technicians replace the broken pump with Sanhua PSB-12A to restore automatic drainage and fix hidden ceiling leakage.
2. Retail Shop Gree/Midea Cassette AC Maintenance Convenience stores and clothing shops install ceiling cassette air conditioners without a downhill gravity drain. Staff install this pump to lift condensed water to the public sewer pipe, preventing water dripping onto merchandise and customer floors.
3. Office Building Facility Routine Replacement Property management teams inspect office floor central AC systems quarterly; aged original drainage pumps malfunction in multiple indoor units. Bulk purchase Sanhua PSB-12A as standardized replacement spare parts for building HVAC maintenance.
4. Wall-mounted Split AC Retrofit for Basement Rooms Basement wall-mounted air conditioners cannot route drain pipes downward for gravity drainage. Home installers add the PSB-12A pump to lift condensate upward and outward to a floor drain, eliminating manual bucket water collection.
5. Air Conditioner After-sales Emergency Repair Service Midea & Gree official after-sales engineers receive service tickets for AC indoor unit overflow and mold smell. They carry Sanhua PSB-12A pumps to replace faulty drain pumps on-site and resolve customer complaints within one service visit.
