Large tank pump – Hot water

The SI 1850 pump is designed to evacuate heavy and contaminated condensates. Capable of evacuating up to 1100 l/h, the SI 1850 pump is suitable for air conditioning units and industrial refrigeration displays. Strong, the SI 1850 tolerates charged, high temperature and acidic condensates (pH>3.4) produced by gas condensing boilers

Large Integrated tank of 3.8 Ltr
Can discharge condensates up to 10m
Suitable for mildly acidic and hot condensate
Thermal protection at 135°C. (auto-reset)
