Up to 500 Bar Pressure Hydro Test System
The Electric Motor or Diesel Engine Driven Hydro Test System is specifically designed for hydrostatic pressure testing applications that require high pressure with comparatively higher flow rates. The system is capable of generating pressures up to 450 bar while delivering a flow rate ranging from 21 LPM to 73 LPM, making it ideal for testing large-volume pressure equipment.
Powered by an electric motor or diesel engine in the range of 20 HP to 40 HP, the system offers flexibility for both in-plant testing operations and on-site field applications where electrical power availability may be limited.
Key Applications
This system is primarily used for hydro testing of:
Pressure Vessels
Industrial Boilers
Large Volume Fabricated Equipment
Heat Recovery Units
High-Capacity Process Equipment
The higher flow rate allows faster filling and pressurization, significantly reducing overall testing cycle time for large components.
Why Higher Flow is Required
In hydro testing of pressure vessels and boilers, the internal volume is relatively large. A higher flow rate:
Ensures quick filling of the test object
Reduces air pockets during pressurization
Enables uniform pressure buildup
Improves overall testing efficiency
