Our High Pressure Desalination Pumps give the following benefits
Low Energy Consumption - Total efficiencies up to 95 percent – among the most efficient in the market.
Long Service Life - Danfoss guarantees service free operation for more than 8000 hours. Pumps correctly operated often run 25,000 to 30,000 hours without service.
- Pump self-lubricated by the water itself
- No need for oil lubrication.
- Few wearing parts
- The design does not require valves inside the pump.
- Corrosion resistant materials
Corrosion Resistance - All wetted parts of the pump are designed in duplex, super duplex stainless steel and polymer, ensuring resistance to corrosive and low viscosity fluids, e.g. seawater and brackish water.
High-Pressure Operation - Continuous operation at a discharge pressure between 10 and 80 bar (145-1160 psi).
Wide Flow Range - One pump size covers the same flow range as several centrifugal pumps, because the flow is a linear function of the speed (rpm).
The pumps run at speeds between 700 and 1500 rpm (APP 10.2), 1800 rpm (APP 5.1 to 8.2), 3000 rpm (APP 0.6 to 2.2).
Constant Flow - Unlike other pump principles, the APP pump provides an almost constant flow regardless of variations in the pressure.
This means that the flow will remain constant irrespective of e.g. a gradual membrane contamination.
Low Pulsation - A design featuring up to nine pistons reduces pressure pulsations in the discharge line down to 1.5 percent, making pulsation dampers unnecessary, and reducing installing cost.
Compact Design - The most compact pump in the market, giving system builders a free hand to design more compact systems
The pump may also be directly mounted onto an electrical motor via a bell housing with a flexible.
