Danfoss APP 21-43

Product Description

The pumps are based on the axial piston principle enabling 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 Danfoss 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.
