Max. inlet pressure = 207 bar (3,000 psi)
Fast fill – system flows up to 100 l/min
Extended service life
Robust design
Flexible design; several boosters/intensification factors
Switch from by-pass to intensified flow
Description
The M-HC-011 In-line Intensifier System is designed to boost the hydraulic pressure from the pump to the workload. It operates only when needed, to save energy.
Typical applications
Mobile attachments; motors – steering systems – cutters – crushers – shears, off highway equipment, injection molding machines and hydraulic presses. Applicable to machines with insufficient pump capacity to prevent machine stoppage when peak pressures occur.
Easy installation
M-HC-011 is provided with four mounting holes for through bolt installation. The four connection ports are placed logically in pairs and in line of each other on the HIC block. All surfaces are electroplated for good protection and fine surface finish.
Functions
The function of the system is simple, but smart. The hydraulic oil is by-passed directly from the pump to the workload at maximum flow when back pressure from the workload has reached a set point close to the maximum pressure of pump.
A sequence valve opens and directs the oil to the booster, which makes the pressure rise. The shift between maximum pump pressure and high pressure happens without intervention from the user and ensures that the workload at all times will be driven at a maximum speed in relation to the required high pressure.
A relief valve is installed to control the maximum allowable pressure that the system can output, and allowing the booster to go for a higher end pressure producing flow at the decided pressure.

Ordering an M-HC-011
Ordering example of an M-HC-011 for 700 bar, connection flange with HC3 i = 3.2, static use:
M-HC3-011-FL55 mounted with HC3-3.2-A-D
Guidance to calculate the intensification factor for dynamic or static use is at the bottom of this section.
Attention note!
Valve pre-settings are required, please specify when ordering the intensifier system.

| M-HC6D-011-1L55 | Tube | 55 l/min | 700 bar | 32.0 kg | M-HC6D-011-1L |

| M-HC3-011-FL55 | Flange | 55 l/min | 700 bar | 7.7 kg | M-HC3-011-FL55-03 |
| M-HC2D-011-FL100-PVG32 | Flange | 100 l/min | 700 bar | 9.0 kg | M-HC2D-011-FL100-PVG32 |

The intensification factor depends on available inlet and desired outlet pressure. To calculate the initial factor, use the following formular:
i = Desired high pressure / pump pressure
Desired pressure: 550 bar
Pump pressure: 207 bar
i = 550 / 207 = 2.7
For static use: Select an intensification factor higher or equal to the calculated value. In this example calculated i = 2.7, select factor i = 2.8 for an HC3 booster.
For dynamic use: Select an intensification factor 40% higher than the calculated value. In this example calculated i = 550 / 207 = 2.66 + 40% = 3.7, select factor i = 4.0 for an HC3 booster. The desired pressure of 550 bar is finally adjusted with the Relief Valve (6).
