Description

Closed circuit
Size 030 042 055 075 100 130 180 250
Series 90
Maximum loads of 480 bar (6960 psi)

Series 90 axial piston variable displacement pumps are of cradle swash plate design with variable displacement, and are intended for closed circuit applications. The flow rate is proportional to the pump input speed and displacement. The latter is infinitely adjustable between zero and maximum displacement. Flow direction is reversed by tilting the swash plate to the opposite side of the neutral (zero displacement) position.
- The Series 90 - Advanced Technology Today
- 8 Sizes of Variable Displacement Pumps
- Complete Family of Control Systems
- Proven Reliability and Performance
- Optimum Product Configurations
- Compact and Lightweight
