Danfoss targets mid-size seawater reverse osmosis with pump launch

Pump manufacturer, Danfoss High Pressure Pumps, has launched its largest positive displacement pump which the company has described as designed for mid-size seawater reverse osmosis (SWRO) plants.

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.
