Product selection
The required ratio = required high pressure / inlet
pumped or regulated pressure. Available ratios can be
selected from the table below. Ensure that the inlet
pressure does not exceed the pressure given in this
table which also offers a guide to approximate charging
flow rates in litres/min.

Description

The HI 11380 Intensifier amplifies the inlet pressure to a higher outlet pressure by a predetermined ratio. Standard ratios are shown in the table above; special ratios are available on request.

Pressure in the high pressure line can become reduced as a result of a system leak or the use of the stored (pressure) energy. Using virtually no energy, the HI 11380 restores and maintains that pressure in such instances. Rapid adjustment of the high pressure line can be achieved by varying the inlet pressure as the high pressure is directly proportional to the inlet pressure. Check and changeover valves are integrated within the main body of the intensifier as is the pilot-operated vent valve in the 11380–xx–02 version. When the inlet pressure x the ratio = the outlet		  
pressure, then the HI 11380 is in a stalled condition and there is no consumption of fluid. The maximum outlet pressure that can be offered is currently 1,500 bars.

Applications

The HI 11380 was designed principally for applications in the offshore oil and gas industry where the highest standards of product performance and durability are essential. The HI 11380 is manufactured from 316 stainless steel to withstand hostile environments; it can operate on all water-based glycol fluids or on mineral and synthetic oils. This product is ideal for charging accumulators from a low pressure supply; it may also be used for operating several different systems from a single supply.
