General description
General description
This apparatus, originally designed for soil mechanics test applications, can also be used to provide an infinitely variable constant pressure and is used in conjunction with the Hoek cell fit with the permeability end caps, for the investigation of the permeability of rock at high confining pressure, in the laboratory. The apparatus comprises: motorized hydraulic pump; honed piston/spring assembly; precision test gauge 0-3500 kPa range; cylindrical oil/water interchange vessel; valves; 2 kg of high viscosity oil.
The lateral pressure can be applied with the 45-D0588 Low friction pressure maintainer or, as alternative, with the 45-D7022/S sercomp S or 45-C7022/RCK Sercomp Rock, servo-hydraulic control console which is part of the Automatic Uniaxial and Triaxial test systems.
  • Pressure range: 0 to 3500 kPa
  • Overall dimensions: 310x300x390 mm
  • Weight approx.: 16 kg
As alternative to oil-water constant pressure system 28-WF4312 it is possible to use new HYDROMATIC standalone closed loop pressure/volume controller:
  • 28-WF45SG: powers 1 hydraulic pressure line and measures the associated volume change. Used for applying 1 level of pressure higher than atmospheric pressure.
  • 28-WF45DG: powers 2 hydraulic pressure line and measures the associated volume change. Used for applying 2 levels of pressure higher than atmospheric pressure.
For typical configurations of Rock permeability test set see Additional information.
