Compact, simple and energy efficient pumps

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.

How it works

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.App pumps how it works
