90L100 axial piston pumps have variable displacement. 90L100 axial piston pumps have cradle swash plate design with intended for closed circuit applications. The flow rate of 90L100 axial piston pumps are proportional to the pump input speed and displacement. The latter is infinitely adjustable between zero and maximum displacement. Flow direction of 90L100 axial piston pumps are reversed by tilting the swash plate to the opposite side of the neutral (zero displacement) position. Read More
