The Si-82 centrifugal pump is designed to be easily installed in any environment. It is capable of evacuating up to 500l/h and suitable for air conditioning units and industrial refrigeration displays. It also tolerates charged, high temperature and acidic condensates (pH>2.5) produced by gas condensing boilers.

The Si-60 is a piston pump with a built-in tank (0,37l) suitable for air-conditioning units up to 20 kW. 

This pump is equipped with the Sauermann piston pump technology specifically designed for removing condensates from air conditioning systems.

Its attractive, ergonomic and compact design makes it easy to install in any place.

The high capacity Si-33 (30l/h) is suitable for air-conditioning units from 20 kW up to 30 kW.

The piston pump inside the Si-33 is specifically designed for removing condensates from air conditioning systems in any environment.

The Si-1822 pump is designed to evacuate heavy and contaminated condensates. Capable of evacuating up to 380 l/h, the Si-1822 pump is ideal for air conditioning units and industrial refrigeration displays. The Si-1822 tolerates charged, high temperature and acidic condensates (pH>3.4) produced by gas condensing boilers.

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

The compact, sleek design of the Omega Pack is the ideal choice for  convenient under unit mounting.  The onboard Si-20 provides you Sauermann's high performance pumping capacities, yet with ultra quiet operation.

Slim design for a quick installation inside the air conditioning unit. 

The Si 1806 is a centrifugal tank pump for gas condensing boilers.

With a 500l/h pumping capacity linked with a compact design the pump is capable of evacuating charged, high temperatures (65°C) acidic (ph >3.4) condensates from gas condensing boilers.
