Mini-Split Condensate Pump Guide: SPS, SPB, SPL, and SPC Series Compared
Share
A standard vertical condensate pump isn't always the right fit for a ductless mini-split — space behind and below the indoor unit is often tight, and the pump needs to mount directly to or near the unit itself. Mini-split condensate pumps are built specifically for that constraint.
Four Mounting Styles, One Spec Sheet
SPB Series
Boxed housing design that sits just below the indoor unit for a clean, enclosed look.
View SPB-66 →SPL Series
Low-profile mounting positioned tight against the wall and unit for minimal visible footprint.
View SPL-66 →SPC Series
Compact side-mount design for installations with limited space beside the indoor unit.

| Spec | Rating |
|---|---|
| Voltage | 100–240V AC, 50/60Hz |
| Max Flow @ 0 Head | 40 L/H (10.60 Gal/H) |
| Sound Level @ 1M | 19 dBA |
| Max Discharge Head | 20M (66 ft) |
| Max Suction Lift | 1M (3.30 ft) |
| Safety Switch | 3A |
| Max Water Temp | 70°C (158°F) |
| Tank Capacity | 40ml (0.011 Gal) |
The universal 100–240V, 50/60Hz voltage range means one pump model can cover both US and international voltage standards, simplifying inventory for wholesalers serving mixed equipment installations.
Built-In Protection Features
- Thermal protection — shuts down the pump motor before heat damage occurs
- Overflow alarm — alerts before the tank overflows, rather than relying on a silent cutoff alone
- Automatic tank cleaning — reduces buildup that leads to premature pump fouling
- Anti-mold tank — helps keep the small reservoir sanitary in a component that's easy to forget during routine maintenance
Quick Answers
Which mounting style should I choose?
It depends on the physical clearance available around the indoor unit — SPS for top-mount, SPB for an enclosed box below the unit, SPL for a low-profile wall-tight install, and SPC for tight side clearance.
Do all four series share the same electrical rating?
Yes — voltage, flow rate, discharge head, and safety switch rating are consistent across the SPS-66, SPB-66, SPL-66, and SPC-66 models; the difference is purely the mounting form factor.
