Sauermann Si-30 Mini Piston Condensate Pump with Remote Detection Float Switch
The Sauermann Si-30 (SI30CE02UN23) is a high-performance mini piston condensate removal pump suitable for air conditioning systems up to 20 kW. 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) @ 1 m — silent operation regardless of condensate volume (EN ISO 3744)
- Drain Safe Device — retains prime and prolongs pump life
- Remote detection unit SI2958 (1.5 m 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 20 kW
- Wall mounted, ceiling suspended, ducted and fan-coil applications
- CE & EAC | RoHS & WEEE compliant
