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

Sauermann SI-10 is a universal quiet condensate removal pump — also known as a mini pump, AC drain pump, or condensate removal pump — designed for wall-mounted split AC, ceiling cassette, fan coil, and ducted systems where gravity condensate drainage is not possible. Piston pump technology delivers quiet, reliable operation trusted by HVAC engineers across the UK.

Key Specifications:

• Flow rate: up to 1,200 ml/hr (20 L/h)
• Voltage: 100–240V AC, 50/60Hz (universal)
• Pump type: piston pump
• Safety device: built-in float switch
• Mounting: multi-orientation
• Housing colour: White
• Country of origin: France
• SKU: SI-10

Compatible Systems:

• Wall-mounted split AC units
• Ceiling cassette units
• Fan coil units (FCUs)
• Ceiling concealed and ducted systems
• Heating and cooling equipment (universal compatibility)

Compatible Brands: Suitable for use with Daikin, Mitsubishi Electric, Fujitsu, Panasonic, Samsung, LG, Hitachi, Toshiba, and most other AC and fan coil brands.

When to Use This Pump:

• Ideal when gravity condensate drainage is not possible — common in wall-mounted splits installed above the external drain level, basement installations, or long horizontal pipe runs.
• Universal voltage (100–240V) makes it suitable for both UK and international AC equipment without adaptation.
• Multi-orientation mounting allows flexible installation in tight or awkward spaces.
• Piston pump technology provides quieter operation than peristaltic alternatives, with low maintenance requirements.

Frequently Bought With:

• Castel DH-ADP96 Flexible Condensate Drain Hose – 50m Coil — standard drain hose for condensate pump installations
• Jubilee Clip 9–12mm — for securing the outlet hose connection
• Sauermann Tee Connectors 6mm – Pack of 5 — for multi-unit condensate drain runs

Frequently Asked Questions:

Can the SI-10 be used with a Daikin wall-mounted split?

Yes. The SI-10 is universally compatible with most wall-mounted split systems where condensate cannot drain by gravity. Connect to the unit's condensate outlet and route the drain hose to a suitable waste point.

What is the difference between the SI-10 and the Sauermann SI-83 tank pump?

The SI-10 is a compact inline pump suited to single indoor units. The Sauermann SI-83 is a larger 2-litre reservoir tank pump designed for higher condensate volumes from larger or multiple indoor units.

Does the SI-10 work on 240V UK systems?

Yes. The SI-10 has universal voltage input (100–240V AC, 50/60Hz), making it compatible with standard UK 240V AC equipment without any adaptation.

Does this pump include a safety float switch?

Yes. The SI-10 includes a built-in float switch that triggers a safety alarm if the condensate level rises abnormally, protecting the indoor unit from overflow damage.

Is this pump suitable for R32 systems?

Yes. The pump handles condensate water only and is refrigerant-agnostic — compatible with R32, R410A, R22, and all other common refrigerants.
