GLOBETECH HYDRAULIC

Dubai, United Arab Emirates

The BV series is available in four versions of single pump (from 8 to 230 L/min at 1200 rpm) and six versions of double pump (from 55 to 370 L/min at 1200 rpm), with maximum powers of over 300 HP.
The BV series pumps are extremely compact and are supplied with ISO norm mechanical couplings and SAE norm hydraulic fittings.
This makes them very easy to install and guarantees their interchangeability with other similar pumps.

USES
The above mentioned valves are generally used for blocking work circuits under pressure, such as guarding against falling loads in the event of pipe breaking.
Hydraulic valves - Dubai - United Arab Emirates

Belonging to the same range of the in line single-acting valves,
but different in that, they allow the valve to open
in the direction that is normally closed
thanks to a particular signal of pilot operated pressure.
The high level of pilot ratio, realized in the design phase,
enables rapid and complete opening for the whole
duration of the desired cycle.

The finish-grinding guarantees aperfectseal
even in particularly adverse working conditions

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

Hydraulic Power Pack COMPACT series is a modular system built around the Universal central manifold.
The ability to mount AC from 0.5 Kw up to 4.0 Kw motors.
Plastic or metal tanks of different sizes from 1, 0 Ltrs up to 30 Ltrs capacity.
The high customization, gives the possibility to use the power pack in both mobile and industrial applications and enables the customer to create hundreds of different hydraulic solutions, using only standard modular parts.

MATERIALS:
Alluminium alloy for die-and shell-casting

Bellhousings are the mechanical elements used to connect an electric motor equipped
with standard flange to a hydraulic pump, thus forming the pump/motor unit.
The bellhousings of this range allow to establish a perfect assembly between
electrical motors with standard flange up to 270 kW and the majority of the
hydraulic pumps available on the world market.

The hydraulic power unit is equipped with two accumulators to cover peak requirements.

4 spools, 320 bar maximum working pressure,
170 lt/min max flow rate.

The internal gear pump draws the hydraulic fluid from the tank and pumps it into the accumulator. As soon as the pressure in the accumulator has risen, the accumulator charging valve switches the pump over to circulation, the pump discharges back into the tank trough the accumulator charging valve at practically no pressure.
A non-return valve prevents the hydraulic fluid from flowing back out of the accumulator. If the pressure in the accumulator drops by 10%, the charging valve switches over and the accumulators are charged again. A pressure reducing valve, downstream of the accumulator, supplies oil to the actuators at a constant, controlled system pressure.

4 spools, 320 bar maximum working pressure,
170 lt/min max flow rate.

The control system covers the following functions:

• Starting the first and second pump
• Moving the winch up and down
• Moving the crane up and down
• Switching from pump 1 to pump 2
• Activating the emergency stop

In modern accumulators the hydraulic uid is separated from the gas by a membrane, a rubber bladder or a piston.
Today, machines with hydraulic drives would be unthinkable without these hydraulic accumulators.
The hydraulic accumulator supports the oil-hydraulics within an exceptionally wide spectrum of applications:
From presses to construction and agricultural machinery to modern wind turbines.
It is particularly important to ensure that the correct conguration of hydraulic accumulator is specied according to different design requirements.
With the introduction of the new Diaphragm Accumulator range with operating pressures of up to 350 bar.
