E-Loop
Hydraulic devices test loop under standard and critical operation conditions.
Performances parameters defined by the standard can be evaluated: IEC 60534, IEC 60193, ISA 72 01 01.
Main characteristics:
- Test line diameter: 25-150 mm
- Multistage pump (135 KW)

D.I.T. (Direct Impact Test)
Particle erosion test plant, to characterize the resistance of materials to erosion by a particle-laden flow.
Main technical features:
- Nozzle exit diameter ≈ 8 mm
