The SI 1805 pump is designed to be easily installed whatever the layout of the premises. Capable of evacuating up to 500 l/h, the SI 1805 pump is suitable for air conditioning units and industrial refrigeration displays. Strong, the SI 1805 tolerates charged, high temperature and acidic condensates (pH>3.4) produced by gas condensing boilers.
