| Miniature peristaltic pump | Wall-mounted split air conditioners and fan-coil units | Approximately 6–18 L/h | Approximately 6–12 m | 12–230 V AC/DC; commonly below 20 W | Low to moderate; installation quality strongly affects sound | Compact size, self-priming operation, suitable for long vertical discharge runs | Space is limited and the drain route requires a relatively high lift |
| Mini centrifugal pump | Residential split systems, ductless units, and small indoor units | Approximately 10–35 L/h | Approximately 5–10 m | 100–240 V; commonly 8–35 W | Low when correctly mounted and isolated from the wall | Good drainage capacity, simple design, widely compatible with HVAC controls | The unit produces a moderate condensate volume with a short or medium lift |
| Tank or reservoir pump | Ceiling cassette units, ducted systems, and commercial fan-coil units | Approximately 20–80 L/h | Approximately 5–15 m | 100–240 V; commonly 15–80 W | Low to moderate; the reservoir can reduce frequent start-stop noise | Handles intermittent condensate flow and provides a visible collection point | Condensate arrives in surges or the air conditioner has a high water output |
| High-head centrifugal pump | Large air handlers, commercial HVAC systems, and multi-zone installations | Approximately 50–250 L/h | Approximately 10–25 m | 100–240 V; commonly 40–250 W | Moderate; vibration isolation and pipe support are recommended | Higher drainage volume and stronger pressure capability than miniature pumps | The required lift, pipe length, or condensate volume exceeds small-pump limits |
| Dual-pump condensate system | Critical cooling rooms, data rooms, hospitals, and high-availability facilities | Approximately 50–300 L/h per operating pump | Approximately 10–25 m | 100–240 V; commonly 50–300 W per pump | Moderate; control panels and alarms may add operational sound | Redundancy, automatic lead-lag operation, and alarm outputs | A pump failure could cause equipment damage, downtime, or service interruption |
| Heavy-duty commercial pump | Large chilled-water air handlers and industrial climate-control equipment | Approximately 100–500 L/h | Approximately 15–30 m | 100–240 V single-phase or 380–415 V three-phase; typically above 100 W | Moderate to high; a dedicated equipment area is usually preferred | High flow capacity, durable construction, and suitability for continuous operation | The installation has a large condensate load and requires commercial-grade equipment |
