The Si 1805 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.

Complete kit intended for wall mounted air conditioning units. Includes an elbow design that can be easily opened by hand by a simple finger push - no tool is needed - and the Si-10 UNIVERS’L pump which incorporates the Sauermann piston pump technology. The Delta Pack's streamlined design complements wall mounted air conditioning units. Low sound level and highly resistance to pollution created by the general environment. 

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.

The Si-27 is suitable for air-conditioning units up to 20 kW. The piston technology is specifically designed for removing condensates from air conditioning systems. The Si-27 is fully reliable in any kind of environment and its sound level remains quiet regardless of the condensate volume.
