APP High Pressure Pumps
Danfoss high-pressure pumps set new standards for small and medium-sized seawater RO applications ranging from 0.6 to 43 m3 /h (2.6 to 189 pm). Their dedicated high-pressure pumps build on decades of experience in developing pumps for other critical applications. Small in size and unsurpassed in engineering quality, the Danfoss range of high-pressure pumps are at the heart of more than 15,000 seawater RO systems throughout the world.
FEATURES AND BENEFITS
Flexible and versatile
• The most compact high-pressure pump on the market, with more power per kilo than any other pump
• More design options than with any other RO pump: no need for frames, belt drives or gear boxes – APP pumps can be installed horizontally or vertically
• Wide flow range, with one APP pump covering the range of several centrifugal pumps
• Constant flow regardless of pressure variations
Low maintenance
• Self-lubricating design – no need for oil lubricants, ever
– The pump’s only seal is on the mechanical shaft
– All pump parts are made of stainless steel (Duplex or Super Duplex) or polymer
• 8,000 hours maintenance free operation*
Low total costs of ownership
• Ultra-low energy consumption
• Market-leading efficiency: up to 97% (volumetric) and 93% (mechanical)
• Permeate cost, with energy recovery, can be reduced to below 2 kWh/m3
• Worldwide support, stock and service networks
