The miniBOOSTER HC6D-B hydraulic intensifier, also called a hydraulic pressure booster, is a high-flow, dual-acting inline unit that uses two alternating pump sections to convert an existing low-pressure hydraulic supply into higher outlet pressure. The HC6D-B is the B-model configuration with an integrated dump valve, allowing pressure on the high-pressure side to be relieved through the booster. When return port R is pressurized and inlet port IN is open to tank, pilot pressure opens the dump valve (DV), allowing fluid from high-pressure port H to return to tank. The HC6D family offers nine intensification ratios from 1.2:1 to 8.2:1, accepts inlet pressures from 20 to 207 bar (290 to 3,000 psi), and produces outlet pressures up to 800 bar (11,600 psi). Depending on the selected ratio, it can deliver intensified flow up to 65 L/min (17.2 GPM) with inlet flow capacity up to 80 L/min (21.1 GPM). Applications include large hydraulic presses and cylinders, heavy-duty workholding and clamping, pressure testing, bolt tensioning, mobile machinery, construction equipment and high-production industrial systems.
