Design and function

F2 is a piston pump with spherical pistons (1) inclu-

ding piston rings (2). The pistons are working at the 

angle of 40° to the shaft (3). When the shaft rotates, 

the pistons move up and down in the cylinder barrel 

(4), forcing the oil to pass from the inlet port to the 

outlet in the end cap (5). A ring gear (6) connects the 

cylinder barrel to the drive shaft, causing these to 

rotate at the same speed.

A barrel support (7) with a spring presses the cylinder 

barrel against the end cap. An internal connection 

from the housing to the suction port eliminates a se

-

parate drain line to the tank. F2 is provided with shaft 

and connection flange that fits direct to PTO´s with ZF 

standard.
