Frequently Asked Questions About Sauermann Products
What’s the difference between Sauermann Si-10, Si-20 and Si-30 condensate pumps?
The key differences between these pumps come down to flow rate, unit size, and where they’re installed.
The Sauermann Si-10 Univers’l is the standard choice for wall-mounted split systems. It’s compact, quick to fit, and works reliably in most domestic or light commercial setups.
The Sauermann Si-20 Slim Fit is ideal for tight installs where trunking space is limited – such as narrow walls or ceiling-mounted units. It’s quieter too, which is useful in noise-sensitive spaces.
The Sauermann Si-30 offers a higher flow rate and better performance in dusty or high-use environments. It’s often used in commercial or busy residential applications where reliability matters most.
All three are quiet, efficient, and built with Sauermann’s anti-siphon technology to reduce maintenance issues. The right model depends on the unit size, site conditions, and available install space.

Can Sauermann pumps be used with all air conditioning units?
Yes – Sauermann pumps are designed to suit most AC systems. The Si-10 Univers’l fits nearly all wall-mounted units, while the Omega Pack and DP10 Delta Pack are pre-packed with trunking and fittings for easy cassette or ceiling installs. For specialist sites, the PE-5200 Peristaltic Pump handles remote or high-lift installs. Just match the right flow rate and mounting style to the system you’re working on.

Do Sauermann pumps come with accessories and spare parts?
Most Sauermann pumps come with fittings included. The Si-10 Univers’l, DP10 Delta Pack, and Omega Pack include trunking, clips, anti-siphon valves, and mounting gear. For service work, you’ll find spare parts like hoses, clips, and replacement heads readily available. Keeping a few extras in stock reduces downtime and avoids return visits.
