Sauermann SI-30 Mini Piston Condensate Pump with Remote Detection Float SwitchThe Sauermann SI-30 (SI30CE02UN23) is a high-performance mini piston condensate removal pump suitable for air conditioning systems up to 20kW. Patented piston technology delivers reliable, quiet operation at 20 dB(A) regardless of condensate volume — the operating sound level remains constant whether the pump is handling a trickle or a full flow. The Drain Safe Device retains prime and prolongs pump life. Remote detection unit (SI2958) allows the sensor to be positioned separately from the pump body, ideal for installations where the evaporator drip tray is not directly accessible.Key Features Patented piston technology — high resistance to pollution, capable of discharging small particles 20 dB(A) @ 1m — silent operation regardless of condensate volume (EN ISO 3744) Drain Safe Device — retains prime and prolongs pump life Remote detection unit SI2958 (1.5m cable) — positions separately from pump body Anti-vibration mounting bracket — reduces vibration transmission to wall/panel/pipework Lockable plug-in power cord — avoids unintended disconnection For AC systems up to 20kW Wall mounted, ceiling suspended, ducted and fan-coil applications CE & EAC | RoHS & WEEE compliant Technical Specifications Part Number SI30CE02UN23 Brand Sauermann EAN 3700543259916 Pump Type Piston Max Flow Rate 20 L/h Max Suction Head 3m Max Discharge Head 10m (flow rate = 4 L/h) Max Pressure 14m (flow rate = 0 L/h) Noise Level 20 dB(A) @ 1m (EN ISO 3744) Mains Supply 230V~ 50/60Hz — 14W Isolation Class Double insulation Protection IP20 Detection Levels On: 16mm | Off: 11mm | Safety: 19mm Safety Switch NC 3A resistive load — 250V Thermal Protection 115°C auto-reset Max Condensate Temp 35°C Operating Temperature +2 to +50°C Max System Capacity 20kW Packaging Weight 0.48kg Safety Standards CE & EAC Country of Origin France What's Included SI-30 piston pump Clear PVC tube Ø int. 6mm — 1m, fitted with Drain Safe Device (pre-mounted) Anti-vibration mounting bracket 1.5m lockable plug-in power cable (2 power wires + 2 safety switch wires) 6 tie wraps (2.5 × 100mm) Detection unit SI2958 (1.5m cable) Rubber elbow 90° Ø int.15 × L 60mm Vent tube Ø int.4 × L 75mm Mounting rail + adhesive Frequently Bought With Castel DH-ADP96 Condensate Drain Hose 50m Sauermann ACC00919 Self-Sealing Fittings — Pack of 5 Also in the Sauermann Mini Pump Range Sauermann SI-10 Universal Quiet Condensate Pump Sauermann SI-20 Ultra-Slim Mini Condensate Pump Sauermann SI-83 2 Litre Condensate Tank Pump Further ReadingWhy Sauermann Condensate Pumps Are So Small — The Engineering Behind the MiniaturisationBrowse our full range of mini condensate pumps and condensate pump accessories.
