  • The UTC-4820 Motorized (Semi-Automatic) Power Pack, controlled by a pressure rate control valve is designed to supply the required oil to the load frames for loading.
  • The power pack can load different frames with required pace rates.
  • A rapid approach pump is supplied as standard.
  • The power pack is equipped with a safety valve (maximum pressure valve) to avoid machine overloading.
  • Maximum working pressure of the system is 400 bar.
  • UTC-4920LP is used with UTC-4820 Motorized (Semi-Automatic) Hydraulic Power Pack for reading the applied load by pressure transducer during the compression tests.
  • Please see the page of UTC-4920LP “LPI Battery Operated Digital Read-Out Unit” for details of the properties.
  • UTC-4920LP Unit should be ordered separately.


  • Low pressure gear pump
  • High pressure durable variable output pump
  • On the dual stage pump, a high delivery low pressure gear pump is used for rapid approach, while a low delivery high pressure durable variable output pump is used for test execution.
  • Rapid approach property of the machine shortens the time interval from when the piston starts moving until the upper platen touches the specimen and helps to save a great amount of time in a busy test laboratory.


  • Dual pump is driven by an AC motor
  • 220 V (110 V), 50-60 Hz single phase and 550 W


  • Safety valve (maximum pressure valve)
  • Pressure relief valve
  • A distribution block is used to control the oil flow direction supplied by the dual stage pump which has the safety valve and pressure relief valve mounted upon it.


  • The tank (20 L capacity) includes enough oil to fill the mechanism which pushes the ram during the test.
  • The level and oil temperature can be seen on the indicator fitted to the tank.
  • Hydraulic motor oil number 46, must be used.


  • Maximum pressure valves to avoid machine overloading
