Condensate Pumps for Air Conditioning & HVAC Systems

Mini, tank, and peristaltic condensate pumps for residential and commercial air conditioning installations — from Aspen, Sauermann, and Blue Diamond. All available from UK stock with same-day dispatch and trade pricing.

Mini Condensate Pumps

The most widely used pump type for wall-mounted splits, ceiling cassettes, and fan coil units. Compact, self-contained, and straightforward to install. The Aspen Silent+ range is the standard specification for bedrooms, hotels, and noise-sensitive commercial installations. Browse mini condensate pumps.

Tank Condensate Pumps

Higher reservoir capacity for larger cassette units, ducted systems, and multi-unit drain collection points. Designed for applications where condensate volume is too high for a standard mini pump. Browse tank condensate pumps.

Peristaltic Condensate Pumps

No impeller in contact with the condensate — highly reliable and virtually maintenance-free. Suited to contaminated condensate, restricted maintenance access, and high-reliability commercial applications. Browse peristaltic condensate pumps.

Choosing the Right Pump

Key selection criteria: max head (vertical lift to discharge point — always add 20–30% safety margin), flow rate (match to system condensate output), noise level (Silent+ for bedrooms and offices), and alarm output (always wire to indoor unit safety input). For ducted units and longer discharge runs, verify max head carefully — consider the Aspen Maxi or a tank pump for vertical lifts over 3m.

Condensate Pumps

Frequently asked questions

What is a condensate pump used for?

A condensate pump removes water produced during the air conditioning or heating process. It is used when gravity drainage is not possible, pumping condensate to a suitable drain point via condensate hose.

What is the difference between Aspen and Sauermann condensate pumps?

Both are leading brands trusted by HVAC engineers. Aspen Pumps are UK-manufactured and widely specified for split and cassette systems. Sauermann offer a broader range including multi-unit and high-head models suited to commercial installations. Read our full Aspen vs Sauermann buying guide for a detailed comparison.

How do I choose the right condensate pump?

Key factors are flow rate, maximum head (lift height), tank capacity, and voltage. For most domestic mini-split systems a standard pump such as the Aspen Mini Orange is suitable. For commercial or multi-unit applications consider a higher-capacity model.

What voltage do condensate pumps run on?

Most condensate pumps for the UK market run on 230V single phase. Always check the specification of the unit you are installing to confirm compatibility.

Can I get next day delivery on condensate pumps?

Yes. We offer fast UK delivery on stocked condensate pumps with tracked shipping options available at checkout.
