Compact design for install versatility

The Si-61 is a piston pump with integrated tank (0,37l) specifically designed to evacuate acidic condensates from gas condensing boilers up to 50 kW.

The Sauermann® technology inside the pump allows the particulate removal and with its innovative float makes it a totally reliable pump for mounting on condensing boilers 

Thanks to its small size, the Si-61 can be easily installed in multiple situations.
