Danfoss launches new high-pressure RO pumps for off-shore

Danfoss has launched the latest update of its APP range, the APP S 674 series of high-pressure pumps designed for reverse osmosis systems. With their small footprints and low-maintenance costs, the new pumps were engineered for offshore rigs where space, weight and reliability are key criteria. But the pumps are also well suited for any application where energy efficiency and worry-free operations matter. The three new pumps have flow rates from 0.8 m3/h (3.5 gpm) and all the way up to 38.4 m3/h (169 gpm).

According to Jesper Bentzen, sales director at Danfoss, the APP S 674 range is ideal for RO systems where produced water is used in a variety of oil and gas applications, including fresh water for drinking and technical water for NOx reduction in gas turbines or injection into wells.

“The offshore industry told us what they wanted, and we listened,” says Bentzen. “The APP S 674 pumps are compact and efficient, and their simple maintenance schedules let operators concentrate on their business, not ours. Everything is crafted in Super Duplex stainless steel, and both the materials and the foundries are NORSOK approved so we can provide full traceability for all pressure-critical parts. The pumps are engineered and certified according to API, and we can also deliver with ATEX if required.”

Like all other APP pumps from Danfoss, the new APP S 674 range 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.
