APP Pump 1.5-3.5

APP 1.5, APP 1.8, APP 2.2, APP 2.5, APP 3.0 and APP 3.5 pumps are designed to supply low
viscosity and corrosive fluids under high pressure, e.g. in seawater reverse osmosis
filtration applications and for high-pressure saltwater pumping.
The pumps are based on the axial piston principle enabling a very light and compact design.

The design ensures that lubrication of the moving parts in the pumps is provided by
the fluid 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 in which the flow is proportional to the number of
revolutions of the input shaft and the pump displacement, regardless of any counter-pressure.
The pumps are supplied with an integrated flushing valve that allows the salt water to flow
from inlet to the outlet, when the pump is not running.

Benefits
• One of the smallest and lightest pumps on the market.
• Can be powered by a combustion engine.
• Long service life / No preventive maintenance required in the warranty period.
• Generates insignificant pulsations in the high-pressure line.
• No oil lubricant required.
• Integrated flushing valve
• All parts of the pump are made of high corrosion resistant materials; e.g. Duplex (EN1.4462/UNS S31803-S32205) and Super Duplex (EN1.4410/UNS S32750), stainless steel and carbon reinforced PEEK
• High efficiency
