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.

Due to its high energy-efficiency and reliability, SWRO has turned into one of the most sustainable and cost effective desalination solutions for land-based, offshore and marine applications. The technology is reliable and safe with high-pressure pumps forcing seawater through desalination membranes to create fresh water. Danfoss supplies expertise and unique technologies that can offer your business high efficiency, low maintenance and flexible configuration.
With efficiency rates up to 92%, the APP pump technology offers the highest efficiency in the industry.
The simple construction of the pump offers reliable operation with long service intervals and easy maintenance.
The small and compact size of the pump allow flexible configuration in almost any environment.
