MiniBOOSTER Hydraulic Intensifier M-HC2D-029-4.0-1K40

Product Description

The M-HC2D – 029 – 4.0 – 1K40 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. Furthermore, the M-HC-029 Intensifier System is designed with a pilot-operated directional valve on the high-pressure side, making it possible to alternately boost the high pressure to respectively the A or B side of, for example, a cylinder. The system has three extended features compared to standalone boosters: sequence adjustment, pressure adjustment and safety relief adjustment. The system is dynamical by means of being able to provide flow at high pressure for intermittent use (< 10 min duty cycle).

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-029 is provided with four mounting holes for throughbolt 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.

Additional information

Specifications

Automatically activated (sequence valve)
High pressure in both directions
High pressure – up to 500 bar (7,250 psi)
Max. inlet pressure = 350 bar (5,000 psi)
Fast fill – system flows up to 40 l/min
Adjustable outlet pressure

Function Description

The system autonomously directs hydraulic oil from the pump to the workload at max flow when workload back pressure nears pump max pressure. A sequence valve channels oil to a booster, increasing pressure seamlessly. A relief valve regulates maximum output pressure, optimizing performance without user intervention.

Ordering an M-HC-029

Ordering example of an M-HC-029 for 500 bar, connection tube BSPP with HC2D i = 4.0, static use:

M-HC2D-029-1K40 mounted with HC2D – 1.6 – 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.

Selection of intensifier system

Ordering code	Connection	Bypass flow	Max. pressure	Weight
M-HC2D-029-1K40	Tube	40 l/min	500 bar	23.0 kg

Selection of intensification factor

HC2D-_._-A-D	HC3-_._-A-D
1.6	1.5
1.9	2.0
2.2	2.8
2.6	3.2
3.2	4.0
4.0	5.0
5.0	6.6
6.6	9.0
9.0

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: 500 bar
Pump pressure: 207 bar
i = 500 / 207 = 2.4

For static use: Select an intensification factor higher or equal to the calculated value. In this example calculated i = 2.4, select factor i = 2.6. The desired pressure of 500 bar is finally adjusted with the Pressure Reducing Valve (5).

For dynamic use: Select an intensification factor 40% higher than the calculated value. In this example calculated i = 500 / 207 = 2.4 + 40% = 3.4, select factor i = 4.0. The desired pressure of 500 bar is finally adjusted with the Relief Valves (6).
