Hydraulic & Pneumatic Pressure Test Bench
Design, Supply & Commissioning
We offer custom-engineered Hydraulic and Pneumatic Pressure Test Benches designed for valve and actuator performance testing under precise and controlled conditions. Our systems are built for accuracy, repeatability, and operator safety, compliant with major international testing standards.
Types
Application
Advanced
- Manual Test Bench – operated by hand pump and gauges.
- Semi-Automatic Bench – basic automation for pressure control and logging.
- Fully Automated PLC-Controlled Test Bench – precise digital control, automatic cycling, and data logging.
- Testing valves, hoses, pipes, cylinders, filters, pressure vessels
- Hydraulic system components (pumps, actuators, fittings)
- Aerospace and automotive — brake systems, fuel lines, accumulators
- Oil & Gas — wellhead components, control systems
- Industrial maintenance — safety and reliability checks
- Ensures product safety and reliability
- Detects leaks, material flaws, or seal failures
- Reduces field failures and warranty claims
- Allows performance validation under simulated real conditions
- Supports R&D and quality control
Main Components
Common Parts:
- Test Chamber / Enclosure – safe area where the component is tested.
- Pump Unit – generates hydraulic or pneumatic pressure.
- Pressure Control Valves – regulate pressure to desired levels.
- Pressure Gauges / Transducers – measure and display applied pressure.
- Safety Relief Valve – prevents over-pressurization.
- Data Acquisition System – records pressure, time, and test results.
- Fixture / Clamping System – securely holds the test component.
- Control Panel (Manual or PLC) – allows the operator to control and monitor tests.
- Reservoir / Compressor – stores test medium (fluid or air).
Working Principle
Hydraulic Test (Liquid Pressure Test):
- The component is filled with water or oil and sealed.
- A hydraulic pump increases pressure to the test level (often 1.5× the working pressure).
- The system is held under pressure for a specified duration.
- Leakage, deformation, or failure is checked visually or via sensors.
Used for valves, hoses, pipes, cylinders, and pressure vessels.
Defination
A Pressure Test Bench is a modular, self-contained test system that uses fluid or gas under controlled pressure to verify that a product or system can safely withstand operating and proof pressures without leakage or failure.
When:
- Hydraulic test → uses oil or water as the pressure medium.
- Pneumatic test → uses compressed air or inert gas (like nitrogen).
Pneumatic Test (Air/Gas Pressure Test)
- The component is filled with compressed air or inert gas (like nitrogen).
- Pressure is gradually increased to the test level.
- Leak detection is performed using soap solution, ultrasonic detectors, or pressure drop monitoring.
