Danfoss announces new pump for RO applications
Danfoss RO Solutions continues to build its range of dedicated high-pressure pumps for small and medium-sized reverse osmosis plants.
The latest addition, APP 38, has a capacity of 38m3/h and is thus the Danfoss APP pump with the largest capacity to date – despite sharing the same small footprint as the APP 21 – 30 pumps. Danfoss is adding the new APP 38 after the successful introduction of the APP 16 – 22 pumps, which the company revealed at IDA in Australia in September 2011.
According to Sales Director Jesper Bentzen, the APP 38 represents an important milestone for the RO division. “Pound for pound, and cubic inch for cubic inch, the APP 38 gives more high-pressure capacity than any other pump on the market. We know from our market research that this one pump can replace many double-pump configurations. And we also expect to break into new segments as customers discover the advantages of such high capacity with a small footprint and low energy bills.”
Like all other APP pumps from Danfoss, the new APP 38 is exceptionally energy efficient, operating at up to 97 per cent volumetric efficiency. The axial piston design results in constant flow regardless of pressure variations, as well as fewer moving parts for improved reliability and reduced maintenance costs. Belt drivers and pulsation dampers are both things of the past with the APP series, and no oil lubrication is needed, as the pumped medium itself lubricates moving parts.
“Energy efficiency and reliability are key parameters for our RO customers,” continues Bentzen, “and our proven performance in these areas is always a door opener. But what often ends up closing the deal is our compact design and small footprint. Our APP pumps can be installed either vertically or horizontally, and they punch way above their weight. This gives our customers, both on and offshore, a lot of design flexibility at very light weight.”
The Danfoss range of APP pumps extends from just 0.6 m3/h and now up to 38m3/h.
Many APP pump sizes are fully compatible with the Danfoss iSave, a revolutionary integrated isobaric energy recovery device that further increases energy savings by up to 60 per cent – and eliminates the need for separate high-pressure flow meters, exchangers and booster pumps.
