General Information
PVG 32 miniBOOSTER
The PVG miniBOOSTER raises the hydraulic pressure from the pump to the workload. It is ideal when you
need an extra high outlet pressure, either constantly or temporarily.
The PVG miniBOOSTER is typically used in mobile attachments, cranes, off highway equipment, injection
molding machines and hydraulic presses. It is applicable to machines with insufficient pump capacity to
prevent machine stoppage when peak pressures occur.
The PVG miniBOOSTER comes in the following three main variants:
HC3-PVG
•
M-HC-010
•
M-HC-011
•
All ordering, inquiries, technical support etc. of the miniBOOSTER products must be directed to
miniBOOSTER Hydraulics A/S. For further information and contact details please visit the miniBOOSTER

HC3-PVG32 miniBOOSTER
The HC3-PVG32 is a compact unit weighing only 4.0 kg. It is ideal for use in a variety of applications where
building up and maintaining high pressure is required. The HC3-PVG32 raises supplied pressure to a
higher outlet pressure and automatically compensates for consumption of oil to maintain the high
pressure. Adjustment of the outlet pressure is carried out by varying the supplied pressure.

Function
The basic operation is illustrated in the function diagram. Oil is fed through the proportional valve PVG32
to the IN port in the HC3-PVG, flowing freely through the check valves KV1, KV2 and DV to the high
pressure side HP. In this condition maximum flow through the booster is achieved giving a fast forward
function.
When pump pressure is reached on the high pressure side HP, valves KV1, KV2 and DV will close. The end
pressure will be achieved by the oscillating pump unit OP. The unit will automatically stall when end
pressure on high pressure side HP is reached. If there is a pressure drop on the high pressure side due to
consumption or leakage, the OP valve will automatically operate to maintain the end pressure. Pressure
can be relieved from the high pressure side HP through the pilot operated check valve DV. By connecting
port R to the supply pressure and port IN to tank, allowing the fluid from the high pressure side HP to
flow back to tank.

M-HC-010
The M-HC-010 In-line Intensifier System is designed to boost the hydraulic pressure from the pump to the
workload. The system operates by solenoid activation. The operator is in full control of the system and
can decide if a boosted pressure to the workload should be applied.
The system is dynamical by means of being able to provide flow at high pressure for intermittent use (<
10 min duty cycle).
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.

The intensification factor depends on available inlet and desired outlet pressure. To calculate the initial
factor, use the following formula:
i = Desired high pressure / pump pressure
Desired pressure: 500 bar
Pump pressure: 200 bar
i = 500 / 200 = 2.5
For static use: Select an intensification factor higher or equal to the calculated value. In this case i = 2.8
with HC3 booster. The desired pressure of 500 bar is finally adjusted with the HP relief valve.
For dynamic use: Select an intensification factor 60% higher than the calculated value. In this case i =
500 / 200 = 2.5 + 60% = 4.0 The desired pressure of 500 bar is finally adjusted with the HP relief valve.

M-HC-011
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.
The system is dynamical by means of being able to provide flow at high pressure for intermittent use (<
10 min duty cycle).
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.
