The Automatic Dual-Stage Hydraulic Power Pack is designed to supply controlled hydraulic oil flow to the load frames during testing operations.
The controller unit features a compact configuration. The Hydraulic Power Pack, Control Unit, and Readout Unit are positioned for easy accessibility, improved productivity, and safe operation.
Performance
- Loading rate: 1 – 20 kN/sec
- Accuracy: °5%
- Rapid approach pump included as standard
- Maximum working pressure: 400 bar
- Maximum pressure safety valve to prevent overloading
- Low noise operation
- Dual Stage Pump System
- The dual-stage pump consists of:
- Low-pressure gear pump
- High-pressure radial piston pump
- The low-pressure gear pump provides rapid approach.
- The high-pressure radial piston pump performs the test execution.
- The rapid approach feature significantly reduces the time between piston start and specimen contact, increasing testing efficiency when multiple specimens are tested.
