Danfoss targets mid-size seawater reverse osmosis with pump launch
Pump manufacturer
The APP 78 pump delivers 78 m³/h – the highest flow rate of any axial piston pump for SWRO use on the market according to Danfoss. In parallel trains, the APP 78 brings
“unprecedented energy savings in SWRO plants” operating at up to 30,000 m³/day said
Danfoss.
The pump uses the well-established axial piston technology that Danfoss deploys in
its smaller pumps. Danfoss said it has targeted the growing market for mid-size SWRO
plants with the APP78 but at flow rates of up to 1,800 m³/d higher-capacity SWRO plants
can also use the device.
“Customers are building more mid-size plants, and they are more focused on energy
efficiency than ever before,” said global sales director at Danfoss, Jesper Bentzen. The
innovative APP 78 delivers “unmatched output for such a compact construction” according
to Danfoss. The new pump design is also available in a 53 m³/h version, the APP 53.
With the latest launches, Danfoss High Pressure Pumps now cover flow rates from 0.6
to 78 m³ /hour. The APP 78 and APP 53 will be available worldwide from the first quarter of 2015.

iSave – isobaric energy recovery device
Danfoss has introduced the first isobaric ERD that is fully integrated with its own positive displacement booster pump and electric motor. The result is fail-safe flow control - without the use of separate high-pressure flow meters.
