The Delta Pack, which includes an Si-10 pump, is a complete kit intended for wall-mounted air conditioning units. The piston technology of the Si-10 is specifically designed for removing condensate from air conditioning systems. With the insulation foam and anti-vibration bracket, the pump's operating sound level will remain very silent (22dBA) whatever the amount of condensate. The pack can be mounted on either side of the unit.

The Si-61 is a piston pump in neutral color, ideal for living spaces, with built-in tank (0.1 gal/0.37 l) designed to remove acidic condensates from gas condensing boilers up to 170 607 BTU/hr (50 kW).

The Sauermann^® technology inside the pump enables small particles removal. Together with innovative float, this technology makes the pump fully reliable in a condensing boiler environment.

White color, small size and low noise level make the Si-61 ideal for an installation in a kitchen.

Sauermann engineers have redesigned the tank pump from the inside-out, making the Si-83 more compact than any other tank pump in its class, all while redefining just how easy tank pump installation and maintenance can be in the field. The Si-83 even comes with a customized Smartphone App that makes installation both simple and intuitive.

The Si-83 is constructed from rugged materials and components for exceptional durability and reliability. The Si-83 tank pump from Sauermann is perfect for residential A/C (up to 20 kW / 60,000 BTU) and heating units (73 kW / 250,000 BTU).
