Danfoss APP pumps are designed for Reverse Osmosis. The high-pressure pumps have versatile applications in land-based, marine or offshore plants.
The APP pumps provide unsurpassed efficiency and great flexibility for configuration. The simple construction of the axial piston pump with fewer parts allows highly reliable operation with long service intervals and easy maintenance.
The Danfoss APP pumps are available in various sizes from 0.6 m3/h to 86 m3/h for use in small and medium-sized SWRO facilities. See the product program below.
Extensive application know-how
Highest efficiency rates in the industry
Compact and small – half size of competing pumps
Long time between service intervals
Easy and service-friendly design
Simple and reliable with high uptime
Short pay-back time

Advanced hydraulics and materials knowhow
The Danfoss Group has pioneered axial piston pump technology in challenging hydraulics applications that have been field tested for over 40 years. Today, Danfoss High Pressure Pumps puts this expertise to work for SWRO.
With more than 15 patents, very small tolerances that are counted in microns – and world-class production know-how in Duplex, Super Duplex and carbon-reinforced PEEK –Danfoss designs and produces the most advanced axial piston pumps available for SWRO.
Ideal for parallel trains that are easy to scale
Danfoss APP pumps are the preferred system builders and OEMs who want SWRO systems with built-in redundancy and modular scalability.
Whether the parallel trains are in separate skids or individual containers, APP pumps are easy to configure. Their compact footprint and simplified connections require no frames or belt drives – and can be installed either vertically or horizontally – also in very tight places.
Our service videos demonstrate how to disassemble and assemble our high-pressure pumps. Service videos are available for APP 0.6-1.0, APP 21-43, and APP 53-86 pumps.
