Series 90 axial piston variable displacement pumps are of cradle swash plate design with variable displacement, and are intended for closed circuit appliions. 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
