The Danfoss PAH High-pressure water pumps are especially designed for operation on technical water, such as reverse osmosis-, demineralised and de-ionised water. Twelve pump sizes with displacements from 2 to 80 ccm/rev in 4 different frame sizes are available providing flow in the range from 50-8000 l/h or 0.25-35 gpm.
The axial piston principle provides very high efficiency, small and compact design and long service life.
The Danfoss pumps are water lubricated and do not involve any other lubricant, making this unique pump maintenance free over its entire service life.
• Maintenance free, due to water lubrication and direct drive (no belt)
• Very high efficiency compared to centrifugal and triplex plunger pumps
• Small, compact and light design
• Negligible pressure pulsation, no need for pulsation dampeners
• Extreme recirculation capability without overheating (up to 90%)
• Wide speed control range
• All stainless steel design Fulfils most stringent hygiene requirements, i.e. VDI 6022, HACCP
• Available as ATEX certified
