Hydraulic Pressure Intensifiers – Single-Stroke Cylinder Type

The Hänchen intensifier is a custom, heavy-duty, pressure intensifier designed for non-standard applications. This model allows the input fluid to be the same as, or different than, the output fluid as a result of its non-reciprocating, axial type construction. Specifically, the primary cylinder can be run with mineral oil and the secondary chamber can be run with a different fluid such as water or water containing media. This type is commonly found in the hydroforming industry. Additionally, higher flow rates can be achieved in this type of pressure intensifier. These pressure intensifiers can be designed with output pressures of up to 5,000 bar/72,500 psi.

Hänchen is a supplier and pressure intensifier manufacturer for various applications including construction, mechanical, marine, and industrial.
