Danfoss High-Pressure Pumps
ForeverPure Place is an authorized distributor of Danfoss high-pressure pumps for seawater desalination, reverse osmosis, water injection, and industrial high-pressure applications. Danfoss APP, PAH, and PAHT axial piston pumps are the world's most widely specified high-pressure pumps for RO desalination systems, trusted by system integrators and OEMs worldwide.
Danfoss Pump Series
Danfoss APP Pumps
The Danfoss APP series covers small to medium high-pressure applications with flow rates from 0.8 to 5.1 m³/h at pressures up to 100 bar. APP pumps feature a compact, self-priming design with ceramic-coated pistons for seawater compatibility and long service life. Common applications include small-scale seawater desalination units, spot water makers, and yacht watermakers.
Danfoss PAH Pumps
The Danfoss PAH series is designed for medium to large seawater RO systems with flow rates from 6 to 55 m³/h at pressures up to 100 bar. PAH pumps use axial piston technology with titanium components for maximum corrosion resistance in demanding seawater service. Used in commercial desalination plants, water injection systems, and industrial high-pressure water treatment.
Danfoss PAHT Pumps
The Danfoss PAHT series is engineered specifically for ultra-high pressure seawater desalination at pressures up to 120 bar, with flow rates up to 55 m³/h. PAHT pumps are designed for new generation low-energy SWRO membranes operating at higher applied pressures for improved water recovery.
