The PF single injection pumps are particularly maintenance-friendly. They have been preferably used in the off-highway segment. They possess the same operating principle as the PE in-line fuel injection pump. They have a pump element, in which the injection volume can be changed by means of a control notch.
Many single injection pumps feature an integrated roller plunger. They then receive the designation PFR. In some versions for small engines, the roller plunger is fitted in the engine. These pumps are referred to as PFE pumps.
