Sauermann SI-10 Universal Quiet Condensate Pump for Mini Split AC Systems

The Sauermann SI-10 Universal Condensate Pump is a compact, high-performance pump designed for removing condensate water from air conditioning systems. Suitable for wall-mounted split units, cassettes, fan coils and ducted systems, it provides reliable drainage where gravity discharge is not possible — with quiet piston pump technology trusted by HVAC engineers across the UK.

When Do You Need a Condensate Pump?

You need a condensate pump when water cannot drain naturally from the indoor unit. This is common in wall-mounted split systems installed above the external drain level, in basement installations, or where long horizontal pipe runs are required.

Key Features

• Universal compatibility — suitable for most heating and cooling equipment, including mini-splits, cassettes and fan coils
• Piston pump technology for quiet, reliable condensate removal
• Compact design for discreet installation in tight spaces
• Flexible mounting — can be installed in multiple orientations
• Built-in safety float switch to protect equipment from overflow
• Low power consumption, easy to clean and maintain
• Universal voltage: 100–240V AC, 50/60Hz

Where This Pump Is Used

The SI-10 is used in air conditioning installations where condensate cannot drain naturally by gravity. It is typically installed alongside the indoor unit and connected to a condensate drain hose to remove water safely from the system. Suitable for domestic and light commercial AC installations across the UK.
