model SPV21, SPV22, SPV23 SPV24, for the excavator, compactor, paver, concret pump. 

Sauer PV series Axial piston variable displacement pumps, Series 20, are of swash plates construction with variable flow capability suitable for hydrostatic transmission in closed loop circuit. 

The Flow  rate is proportional to the pump´s driven speed and displacement, which, in turn, is  determined  by the swash plate  angle.  The  latter  infinitely  adjustable  between zero and maximum displacement. 

Flow  direction  is  reversed by tilting  the swash plate  to the opposite  side  of  the neutral  or zero displacement position.
