Sauermann Si-52 Peristaltic Pump - Technical Datasheet
Product Overview
The Sauermann Si-52 is a peristaltic pump designed for efficient condensate removal from air conditioning systems with power ratings up to 8 kW. It is suitable for various AC types including wall-mounted, cabinet, ceiling, and ducted units.
The pump features a float-based detection system with three liquid level settings (ON, OFF, ALARM). A safety contact mechanism is integrated to automatically shut down the air conditioner compressor or solenoid valve, thereby preventing condensate overflow and potential water damage.
Note: The Si-52 is not designed for continuous operation.
