Durable pump

The SI 1830 pump is designed to be easily installed whatever the layout of the premises. Capable of evacuating up to 400 l/h, the SI 1830 pump is suitable for air conditioning units and industrial refrigeration displays. Strong, the SI 1830 tolerates charged, high temperature and acidic condensates (pH>2) produced by oil condensing boilers.

Heavy duty IPX4 design
Oil and acid resistant float
Mechanical structure resistant to shocks
Can discharge condensates up to 3.7m
Up to 400 l/h, for shorter running time
Low sound level – quiet operation
Pump can be floor mounted, attached on a wall or stand alone without tank.
Easily removable tank and reversible pump, to allow mounting rather on the left or on the right of the application and choosing the side of the water exit.
