Cyclic pressure, proven to 100,000 cycles.

Why cyclic pressure testing matters

The Pressure Cycle Test System is a critical solution for validating the durability and reliability of components exposed to fluctuating pressures. Designed to simulate real-world operating conditions, this Pressure Cycling Test Rig ensures safe component performance across industries such as aerospace, automotive, hydraulics, and energy.

As a Hydraulic Pressure Cycling Test Rig or Pneumatic Pressure Cycle Testing Bench, the system subjects components to repeated loading, helping engineers assess fatigue strength and service life. Precisely monitoring pressure-versus-time profiles — the same data a Pressure-Versus-Time Test Bench or Pressure Fatigue Test Stand records — gives accurate, repeatable data for endurance evaluation.

For demanding environments, the rig behaves as a High-Pressure Cycling Test Rig or Pressure Pulse Testing System, replicating extreme pressure variations to uncover potential weaknesses. Applications range from a Component Endurance Test Stand for mechanical parts to a pressure test system for tubes and hoses, or a Valve Pressure Cycle Test Bench for individual valve qualification.

1. Dual-pressure output & test capacity

The system generates two independent, simultaneous pressure outputs:

• High pressure: 0–2000 psi (138 bar)
• Low pressure: 0–500 psi (34 bar)
• Cycle rate: Adjustable from 1 to 10 cycles per minute, tracked on Omron digital counters
• Total capacity: Up to 100,000 cycles per test programme

As an Automated Pressure Cycle Test Machine and Programmable Pressure Cycling System, cycle parameters are set once and the rig runs unattended — functioning as a Burst and Fatigue Life Testing Rig or Pressure Repetition Testing Unit through to completion or failure detection.

2. Hydraulic power pack & filtration

Hydraulic power pack

A 200-litre SS-304 stainless steel reservoir with fluid-level indicator and temperature controller feeds an explosion-proof gear pump rated 2000 PSI at 300 GPH, driven by a 7.5 kW motor. A bladder accumulator absorbs excess pressure to minimise fluctuations, while a heat exchanger maintains operating temperature between 15°C and 35°C.

Contamination-free filtration

A suction strainer and pressure-line filter combine 6-micron absolute filtration on the pressure line with 10-micron nominal filtration on the return line. Non-bypass, explosion-proof filters with clogging indicators ensure test fluid remains contamination-free throughout every cycle.

3. Measurement, control & data acquisition

The system employs advanced instrumentation for real-time monitoring and analysis:

• Digital pressure indicator: 0–3000 PSI gauge with ±0.25% accuracy.
• RTD-based temperature monitoring: continuous fluid temperature tracking.
• Solenoid-operated DC valves: precise, repeatable fluid control.
• Real-time data acquisition: graphical visualisation and logging for detailed performance analysis and compliance reporting.
• Touchscreen control panel: user-friendly interface for automated operation and remote monitoring.

4. Safety mechanisms & interlocks

Automatic shutoff conditions include:

• Motor overload or high temperature
• Overpressure detection
• Low fuel/fluid level
• Phase failure protection

An emergency stop button gives operators instant system shutdown, while quick-disconnect couplings (QCDC) with non-return valves (NRVs) prevent fluid spillage and contamination during hose changeovers between test articles.

5. Construction, mobility & durability

Built from SS-304 stainless steel for corrosion resistance, the rig uses globally recognised brands for pumps, motors, and sensors, and is wheel-mounted for easy relocation between test setups. Each unit undergoes 100% quality testing and performance validation for cycle accuracy and emergency shutdown response before dispatch.
