The A7V is a variable displacement axial piston pump featuring a bent-axis design, specifically engineered for hydrostatic transmissions in open circuits. Flow is proportional to drive speed and displacement, with stepless variability at constant drive speed. Available sizes include A7V20, A7V28, A7V40, A7V55, A7V58, A7V78, A7V107, A7V117, A7V160, A7V250, A7V355, and A7V500. Control options include LV, DR, EL, HD, and MA devices.
