Danfoss APP pump runs maintenance-free for 11 years
More than a decade ago, Watec replaced a traditional reciprocating pump with an axial piston pump from Danfoss. The pump was installed in a plant on a remote island, so reliability was crucial. Today, the pump continues to run maintenance-free while millions of gallons fresh water have been produced – resulting in a low total costs of ownership.
Qualification of APP pumps and iSave ERDs
Our high-pressure APP pumps and iSave energy recovery devices have been tested by NavSea and are now qualified for operation in harsh environment onboard US military ships. Further, the tests have proved high energy efficiency with more than 70% savings compared to systems being used today.
Desalination at sea
Danfoss high-pressure pumps are extremely versatile and can fit many application types. See how our APP 78 pumps and iSave 70 pressure exchangers can make fresh water production possible at sea.
New iSave 21 Plus
Danfoss launches a new generation of the popular iSave 21 ERD for smaller SWRO plants. Improved reliability, design flexibility and high efficiency are some of the features of the new iSave 21 Plus.
