Sauermann SI-1805 Centrifugal Tank Pump

Sauermann Si-1805 Centrifugal Tank Pump

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.

High Performance

• Can discharge condensates up to 5.4 m.
• Up to 500 l/h, for shorter running time.
• Low sound level – quiet operation.

Versatile

• 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.

Easy Hydraulic Connection

• New quarter turn easily removable check valve, designed to facilitate Ø int. 10 mm (3/8”) hose
  plug in.
• 2 inlet holes Ø 24 and 21 mm
