Automatic Cyclic Pressure/ Volume Controller (Cyclic VPC)
Cyclic Volume Pressure Controller is a High Accuracy Advanced Electro mechanic or servo hydraulic Closed-loop controlled Pressure System for Static and Cyclic Confining or cyclic Pore water pressure up to 4000 kPa with volume change control up to 1000 ml with different range of working frequency up to 10 Hz.
This series of pumps is available in single or twin configurations and can be either electromechanical or servohydraulic, depending on the test frequency requirements.
