Danfoss highlights RO applications on new website
Pump manufacturer Danfoss has launched a new website which features reverse osmosis applications of its modular axial piston pump (APP).
The new site (www.ro-solutions.com) features Danfoss’ modular, containerised APP along with its
iSave energy recovery devices (ERDs). The iSave combines an isobaric pressure exchanger, booster
pump and motor to reduce substantially its size compared with separate devices according to
Danfoss. This, coupled with the APP’s capacity to produce flow rates delivered by centrifugal pumps
twice its size creates an exceptionally compact array the manufacturer says.
The modular design of the APP makes it possible to configure multiple pump and ERD arrays;
scale pumping capacity to demand; and configure parallel systems. “Instead of a plant becoming
obsolete due to limited output, it can be turned into one of several modules that work together as a
single system,” says Danfoss.

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.

Non-return valves by Danfoss
Our range of Super Duplex and Duplex stainless steel non-return valves feature a conical poppet design to ensure a perfect seal when used with a low-viscosity medium such as seawater.
