Shop MiniBooster HC6-A Hydraulic Intensifiers without Dump Valve
The miniBOOSTER HC6-A hydraulic intensifier, also called a hydraulic pressure booster, is a high-flow inline unit that converts an existing low-pressure hydraulic supply into higher outlet pressure. The HC6-A is the A-model configuration without an integrated dump valve, so high pressure must be relieved externally, typically through a properly sized pilot-operated check valve. This arrangement is especially useful with large-bore hydraulic cylinders that generate high return flow better handled outside the booster. The HC6 family offers nine intensification ratios from 1.3:1 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 28.3 L/min (7.5 GPM) with inlet flow capacity up to 80 L/min (21.1 GPM). Applications include hydraulic presses, large cylinders, heavy-duty workholding and clamping, pressure testing, bolt tensioning, mobile machinery, construction equipment and industrial automation.
The HC6-A provides localized high pressure and substantial flow without requiring a separate high-pressure pump or power unit, helping reduce system size, piping, energy use, noise and equipment cost. It automatically stops intensifying when the required pressure is reached and restarts if pressure falls because of fluid consumption or leakage. Warning: The HC6-A has no integrated dump valve or internal means of relieving trapped high pressure. The circuit must include a correctly designed and appropriately sized external pressure-release method capable of handling the expected return flow. Never assume the high-pressure side has been depressurized; confirm zero pressure with a properly rated gauge before service. Select the intensification ratio using maximum inlet pressure, return backpressure, required outlet pressure and flow demand, and ensure all hoses, fittings, valves, gauges, seals, manifolds and actuators are rated for the maximum possible intensified pressure. Installation must be performed by qualified hydraulic personnel.
