High-pressure pumps for reverse osmosis applications

Energy efficient pumps for desalination

With Danfoss high-pressure APP pumps tailored to Sea Water Reverse osmosis (SWRO) applications you will get one of the most reliable and sustainable pumps for desalination. The APP pumps can be used in almost any SWRO application – land-based, offshore or marine. Mounted in containers or trains, the APP pumps can contain several pumps in parallel to secure uninterrupted and sufficient supply at any time.

Danfoss has pioneered axial piston pump technology in challenging hydraulic applications for several years. With more than 15 patents, a strong precision engineering heritage and world-class production know-how in Duplex, Super Duplex and carbon-reinforced PEEK, Danfoss designs and produces the most advanced high-pressure pumps available for reverse osmosis. The APP pump is oil-free, using only water for lubrication. Most pumps can be delivered with ATEX and API 674 approvals.

The Danfoss APP pumps are available in various sizes from 0.6 m3/h to 92 m3/h for use in small and medium-sized SWRO facilities.
