The SI 1805 pump is designed to be installed in a variety of conditions. With a flow rate of up to 500 l/h, the SI 1805 is ideal for air conditioners and refrigerated display cases.
In addition, its robust design and suitability for discharging dirty, high-temperature and acidic condensates (pH > 3.4) make it suitable for use in gas condensing boilers.
Advantages:
- Can drain condensate up to a height of 5.4 meters
- Flow rate up to 500 l/h, with shorter operating times
- Low sound level quiet operation
- Easily removable tank and reversible pump to allow it to be mounted on the right or left side of the unit and thus choose the condensate outlet side
