Standard Pumps For Tap Water Type PAH
High-pressure pump range based on the axial piston principle (5–9 pistons) enabling a very light and compact design. Very low pulsation and airborne noise.
PAH 2/4/6.3, PAH 10/12.5, PAH 20/25/32 and PAH 50/63/70/80/100 are pumps designed to supply water flow under high pressure. The pumps are based on the axial piston principle enabling a very light and compact design.
The pumps are designed so that lubrication of the moving parts in the pumps is provided by the water itself. No oil lubrication is thus required.
All parts included in the pumps are designed to provide long service life, i.e. long service life with a constantly high efficiency and minimum of service required.
The pumps are fixed displacement pumps where the flow is proportional to the number of revolutions of the input shaft and the pump displacement.
