miniBOOSTER® – Pressure Boosters

Tensioning devices in machine tools where various working steps such as rough machining, smoothing and polishing are carried out at different clamping pressures in order to prevent clamping delay. Directly proportional pressure boosters correspond to the standard HC datasheets in all dimensions and functionality. The only external difference is the designation.

Input pressure:

• 20 bar to 200 bar

Output pressure:

• Up to 800 bar (HC1 / HC2 / HC 4 / HC6 series)
• Up to 2000 bar, higher on request (HC7 / HC8 series)
• Up to 5000 bar, higher on request (HC9 series)

The HC2D is a dual action unit with a high throughput which can achieve flow volumes of up to 11.0 l/min at the high-pressure end. Like other miniBOOSTER^® models, the HC2D boosts the input pressure to a higher output pressure and automatically compensates oil consumption in order to keep the high pressure constant. The output pressure is set by adjusting the input pressure. Considering its delivery rate, the HC2D is a compact device which weighs just 3.8 kg.

The HC6D is a dual action unit with a high throughput which can achieve flow volumes of up to 56.0 l/min at the high-pressure end. Like other miniBOOSTER^® models, the HC6D boosts the input pressure to a higher output pressure and automatically compensates oil consumption in order to keep the high pressure constant. The output pressure is set by adjusting the input pressure. Considering its delivery rate, the HC6D is a compact unit which weighs just 20 kg.

• Input pressure: 20 bar to 200 bar
• Output pressure: Up to 800 bar

This pressure booster is used for hydraulic systems designed on a modular basis. The connection schematic based on NG6 standards allows it to be fitted without pipework. Fitting the pressure booster right next to the application guarantees rapid response times in terms of pressure build-up. Use within the NG6 standard means the maximum operational pressure must be reduced to 500 bar. * NG 10/16/25 on request

Input pressure:

• 20 bar to 200 bar (lower pressures on request)

Output pressure:

• 20 bar to 500 bar with M5 screw fitting (standard NG6 system)
• 20 bar to 800 bar with M6 screw fitting (deviation from NG6 system)

The HC3-D and HC3-F pressure boosters are used for hydraulic systems designed on a modular basis. The miniBOOSTER^® connection schematic allows them to be fitted without pipework. Fitting the HC3-D or HC3-F right next to the application guarantees rapid response times in terms of pressure build-up. Use based on the miniBOOSTER^® connection schematic means the maximum operational pressure must be reduced to 500 bar.

Input pressure:

• 20 bar to 200 bar

Output pressure:

• 20 to 500 bar with M5 screw fitting
• 20 to 800 bar with M6 screw fitting

The HC5 pressure booster is used if high pressure is required on both sides of a dual-action cylinder or on both sides of a hydraulic swivelling device. This means that there is no need for switching valves in the high-pressure system. Typical applications include cutting and spreading devices, etc.

• Input pressure: 20 bar to 200 bar
• Output pressure: Up to 800 bar

The HC2D2 is a naturally aspirated 2-media booster which can achieve throughput of 3l/min. on the high-pressure side. Like other miniBOOSTER^® models, the HC2D2 increases the input pressure so that the output pressure is higher and automatically compensates the oil consumption in order to maintain the high pressure. The output pressure is adjusted by setting the input pressure. Relative to its throughput capacity, the HC2D2 is a compact device which weighs just 4.15 kg.

The HC6D2 is a naturally aspirated unit for two media which can achieve flow volumes of up to 41 l/min at the high-pressure end. Like other miniBOOSTER^® models, the HC6D2 boosts the input pressure to a higher output pressure and automatically compensates oil consumption in order to keep the high pressure constant. The output pressure is set by adjusting the input pressure. Considering its delivery rate, the HC6D2 is a compact unit which weighs just 24 kg.

• Input pressure: 20 bar to 200 bar
• Output pressure: Up to 800 bar
• Design: Only available as A-variant; outlet screw max. 10 bar pressure

Pressure booster pump used in battery-powered or pallet applications. The HC2P consists of a geared pump and an HC2 miniBOOSTER^® pressure booster. As with the other pressure booster models, the oil is compressed on the high-pressure side. The high pressure is adjusted by controlling the low-pressure side using the geared pump. The default setting for the geared pump is 50 bar.

• Input pressure: 0.4 bar to 2 bar (on the pump suction line)
• Output pressure: Max. 650 bar (higher possible on request)

The portable system is perfect for mobile fittings in order to utilise the full pump capacity for the express function of the hydraulic cylinder(s) and boost pressure and generate high pressures where required (crushing/clamping). Typical applications: Mobile fittings (cutters, crushers, shearing) for injection moulding machines and hydraulic presses.

• Extremely robust
• The system is delivered fully mounted and factory-tested and is ready for immediate installation
• High throughput rate and high pressure
• Available in models with different boost factors
• Various connection options
• The device is available with a range of fitting options

The miniBOOSTER^® M-HC7 portable pressure booster system is a robust device designed for used in demanding industrial applications. The M-HC7 can be used in conjunction with any low-pressure device (20 to 200 bar) which delivers a volume flow of at least 2 l/min. It can achieve output pressures of up to 800 bar. The unit is designed with reliability in mind. The M-HC7 is fitted with a 10 µm filter and a visual filter status display. This increases service life and reduces downtime.

Time is money: The M-HC7 can deliver up to 15 l/min and is designed to add the system capacity to the working process as soon as a pressure boost is required. This minimises cycle times. Many applications require extraordinary precision from the device. The M-HC7 has an easy-to-read manometer with a 4-inch (approx. 10 cm) diameter which enables an accuracy of 1 % (up to 10 bar>).

• Bolt stretchers
• Lifting systems
• Rail systems
• Crimping/cutting systems
• Rescue equipment
• Torque range

With a weight of just 10 kg and a practical carry handle, the device can be used anywhere it is needed. The M-HC7 works with an existing hydraulic low-pressure supply. No additional tools are required. All the controllers built into the device make it simple to operate and reliable to use.

Input pressure:

• 20 bar to 200 bar (M-HC6 /M-HC7 series)
• 20 bar to 350 bar (M-HC7 series)

Output pressure:
