APP pump range expansion gives new options for SWRO

Tuesday, May 14, 2019

SWRO system designers and installers have trusted Danfoss axial piston pump (APP) technology as a high-efficiency and highly flexible solution for many SWRO applications — land-based, offshore, and marine.

And for good reason. The APP pump range delivers efficiency rates as high as 92%. APP pumps are also easy to maintain and can go a long time between service appointments.

To date, the Danfoss APP pump range included sizes as low as 0.6-1.5 and as high as 53-86. Now, we’re ready to offer an additional size to make the range even more flexible and give our customers even more options.

The new Danfoss APP 92 is an extension of the APP 53-86 and is an ideal choice for medium-sized SWRO plants. It can easily run in parallel, resulting in higher flow.

The compact size and low weight of the APP pumps allow flexible configuration in almost any environment. They are also easy to maintain and can be serviced in the field, which makes the pump ideal for use in remote locations.

Pueblo Bonito Sunset Beach Golf & Spa Resort, a popular luxury resort, replaced an aging reciprocal pump with a new Danfoss APP pump, netting them simplified maintenance, high energy cost savings, and a low total cost of ownership as fresh water flows 24 hours a day, 7 days a week.

Case studies

  • Suez chooses oil-free Danfoss APP pump to power Bahamian RO plant retrofit

    For a resort in Bahamas APP pump and iSave ERD were selected to supply fresh water. Both components are well-known for long service intervals, high reliability and energy efficiency. They eliminate risk of oil contamination on the plant site, as they use the pumped medium for lubrication.

  • Seawater
    Creating a sustainable future with seawater

    Over the past decade, the use of Sea Water Reverse Osmosis (SWRO) for desalination has taken off. With proven efficiency rates up to 92% and energy savings of up to 65% compared to traditional solutions, the opportunities of SWRO technologies deserve further exploration.

    Canaragua uses Danfoss pumps and ERDs for ultra-compact RO plant in Gran Canaria

    Even though Canaragua has installed dozens of SWRO plants throughout the Canary Islands, the project in Puerto de Mogán was unusual because of the focus on compactness. The municipality needed to expand water production, and the best place to locate the new plant was in the middle of the historic town right off the main square.
