Uses for Danfoss APP 11-13
The pumps are based on the positive displacement principle (axial piston design) which enables a very light and compact design, and they are designed so that the lubrication of the moving parts in the pumps is provided by the fluid itself. No oil lubrication is thus required.
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.
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 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.
