Our pressure intensifiers provide closed-loop, servo- controlled pressure to test samples. This can be used to generate confining or pore pressure in connection with multi-channel electronically controlled systems that manage servo-valves mounted to intensifiers. They are also used to measure permeability or for hydro-fracturing tests.
Intensifiers can be used to measure flow in permeability tests as well as volume change in triaxial tests while the required pressure is applied.
Separate hydraulic power is needed to supply a primary power source to the pressure intensifier. This pressurizes fluid to 21 MPa (3,000 psi), which in turn fills the intensifi er’s reservoir. The fluid in the reservoir can then be brought up to the required pressure by the intensifier. A double-pump or a dual piston intensifier with two servo-valves is available as an option for precise pressure or volume control when continuous flow is required.
