Harwood Engineering Company Single Acting Intensifier

For situations where the intended use is for something like small compactions and fatigue machines, a single acting intensifier has the advantage of increased packing life and significantly easier maintenance as opposed to a double-acting intensifier.  For applications where the desired pressure can be achieved in a single stroke it is sensible to use an SA over a DA as it is less expensive, less of a hassle to change packings, and hence less down time for maintenance.
