DV Hydraulics developed and built an advanced hydraulic test installation, designed for performing high-pressure tests up to 4000 bar.

This installation is equipped with proportional pressure control and combines precision, safety, and user-friendliness in one compact unit. The installation was fully tailored to the specific requirements of the customer and configured for reliable operation, even under prolonged load and extreme pressure levels.

Technical Specifications

• Proportionally adjustable pressure control between 0 and 4000 bar, for both increasing and decreasing pressure

• Short cycle time of approximately 1 second, depending on dead volume

  • At a volume of 500 cc, the compressibility of oil results in a compression of nearly 31% at 4000 bar (approximately 156 cc)

  • With a secondary flow rate of 0.3 liters/min, this corresponds to ±30 seconds filling time

• Installed electrical power of 4 kW, sufficient for stable operation of the installation

• Primary hydraulic circuit:

  • Pressure: 250 bar

  • Flow rate: 8 liters per minute

• Secondary flow rate with water: approximately 0.3 liters per minute when the desired test pressure is higher than the primary pressure

• Hydraulic tank with a capacity of 120 liters, equipped with:

  • Temperature protection

  • Level protection

• Air-cooled system with:

  • Circulation pump

  • Built-in filter

• Electrical control cabinet with extensive functions:

  • Start/stop operation

  • Monitoring of the installation

  • Emergency stop provision

  • Stabilized power supply

  • Selector switch for testing at 1000 or 4000 bar

• Pressure control module with control valve for precise and stable pressure regulation in the secondary circuit

• Pressure sensors for 1300 bar and 4000 bar

Construction & Test Area

• Steel chassis with the following dimensions:

  • Length: 2000 mm

  • Height: 2000 mm (working height: 900 mm)

  • Depth: 900 mm

• Fully enclosed with steel plates to optimally secure the high-pressure section

• Integrated drip tray under the work surface

• Entire construction painted in RAL 9010

• Lockable test compartment:

  • Width of 1000 mm

  • Closure via a steel door

  • Door equipped with an electrical contact for safety

• Stainless steel test block mounted on the work surface

Reliable Performance at Extreme Pressures

This high-quality test installation offers an accurate, safe, and efficient solution for applications requiring tests at extremely high pressures. Thanks to its modular design and flexible configuration, the system can be easily adapted to a wide range of test requirements. The combination of advanced technology and maximum safety features makes this installation ideal for critical test environments where reliability and control are essential.
