Robust Pump

The SI 1830 is a centrifugal tank pump with IPX4 protection.

The pump has been designed to be capable of processing acidic (pH> 2) & high temperature condensates (80°C max) and can be used on oil boilers.

With a range of up to 400 l / h, the SI 1830 is also ideal for air conditioners and refrigerated display cases.


Robust design with protection IPX4
Float resistant to acids and fuels
Reinforced shock-resistant construction
Ability to discharge condensate up to a height of 3.7m
Capacity up to 400 l / h, with shorter operating times
Low sound level
The pump can be installed in the floor, wall or inside the tank without tank
Easily removable and reversible pump reservoir to allow mounting on the right or on the left of the unit and to be able to choose the output side of the condensate
