Our condensate tank pumps are designed to withstand the tough conditions found in large-scale heating, air conditioning and refrigeration systems.
These models are powerful and durable enough for use with central boilers, refrigerated display cabinets, freezers and multi-cassette air conditioners – all of which produce hot, acidic, fouled, biofilm-heavy and other special types of condensate in large volumes.
Si-82 or Si-83? Choosing between our two star models
Si-82: a workhorse for heavy-duty use
The Si-82 is designed for heavy-duty use with powerful systems that demand a reliable tank pump. It can withstand any conditions, removing up to 500 litres an hour and making light work of even the most aggressive condensates.
This tank pump is therefore ideal for powerful systems such as multi-cassette and ducted air conditioners, dehumidifiers, refrigerated display cabinets and gas-fired condensing boilers.
- Fits into any location
- Rugged design and outstanding performance
Si-83: a modern, clever pump for residential use
Sauermann designed the Si-83 with several requirements in mind. The first was to build a model that was more compact than anything else in its class: this pump stands at just 129 mm tall and boasts a 2-litre tank. The second was to offer versatility and unmatched ease of installation. And the Si-83 delivers on this front too, with five condensate inlet options and a mobile app that makes installing it a breeze.
This condensate tank pump is designed for residential use. It’s compatible with air conditioners of up to 20 kW and gas-fired condensing boilers of up to 40 kW.
- Easier to install than anything in its class
- Quick, hassle-free servicing
Si-83 Mobile App
- Step-by-step installation guide
- Horizontal level checker
- Installation-specific accessory finder
- Automatic calculations to check installation topology
- In-built flashlight function
