Sauermann has completely redesigned the centrifugal tank pump to make the Si-83 the most compact in its class while redefining ease of installation and maintenance. The Si-83 comes with a dedicated smartphone App for easy and intuitive installation.

 

The Si-83 is made with robust materials and components to achieve exceptional levels of durability and reliability. Extremely multi-purpose, the Si-83 is ideal for both residential air conditioning (up to 20 kW) and heating systems (up to 40 kW).

 

Advantages:

• Detection float designed to resist fouling
• Stainless steel motor shaft
• Ability to tolerate acidic, high-temperature condensate (pH > 2.5) produced by gas condensing boilers
• Designed for intuitive installation
• Can be mounted on the floor, wall or suspended from the ceiling
• 5 condensate inlet options for unmatched installation flexibility: 4 inlets on top, one on the side of the tank
• Mounting bracket system for easy leveling
• Easy installation under luminaires due to its particularly low profile: 129 mm high
• Dedicated smartphone application (available for iOS and Android devices)
• Maximum pressure: 5.7 m
• IP44 degree of protection
• Reservoir capacity: 2 lilts
• No need to remove the pump from the system to clean it
• Removable check valve
