| Pumping Systems |

|
|
| a) Air Operated Hydraulic Pumping Systems to 50,000 psi |
|
| High Pressure air operated hydraulic pumping systems are complete, self-contained units and ready to operate. Just hook up standard shop air supply (maximum 100 psi) to connection supplied on the side of the console. Discharge capacities range to 64 in3/min.
System includes hydraulic oil reservoir, oil filter, air operated hydraulic pump, pressure gauge, panel mounted high pressure valves, safety head assembly, panel mounted air regulator and gauge and air line filter and lubricator. All components are enclosed in a steel console with only the back exposed. Dimensions of standard systems are 26" wide, 24" deep and 40" high. |

|
| b) System Capabilities |
|
The output pressure is predetermined by adjustment to the air regulator setting
Output pressure is maintained constantly and pump compensates for pressure drops or losses.
Hydraulic input is gravity fed, however, if pump is used alone, the feed can be pressurized to the limit of the pump. Within the pump the large diameter air piston drives a smaller piston to provide fluid flow at high pressure.
Air consumption will be approximately 56 CFM of free air at 100 psi input.
Reservoir = 4 gallon capacity, do not pressurize. |

|
| c) 150,000 psi Pumping System |
|
The Pumping System is designed for generating hydraulic pressure up to 150,000 psi by means of an air operated hydraulic pump and an intensifier. The 10 to 1 ratio intensifier is fully illustrated on facing page 11.5. This system is complete and ready to operate requiring only the connection of an air supply of approximately 80 psi.
The steel console is 26" wide, 24" deep, 40" high and includes manual valves, air regulator, filter and lubricator, air gauge, high pressure gauge, reservoir, oil filter, pump (0-16,000 psi), related high pressure tubing and fittings.
|
 |
|
The 0-20,000 psi pressure gauge is connected to the low pressure side of the intensifier which has a ratio of 10 to 1. Pressure on the high pressure side of the intensifier is thus determined by multiplying the gauge reading by 10. A small variation must be allowed for friction from the intensifier packing.
The air operated hydraulic pump pressurizes the system to 16,000 psi with valves “A” and “B” closed and the intensifier piston is automatically positioned to the low pressure end of its stroke. With valves “A” and “C” closed, valve “B” is opened to allow the pump to pressurize the low pressure end of the intensifier. The fluid in the high pressure end of the intensifier is thus pressurized with a 10 to 1 ratio. If the intensifier reaches the end of its stroke before the desired pressure is achieved, the intensifier may be recycled. The intensifier output is approximately 1.2 cubic inches per stroke.

| Intensifiers |
|
|
|
|
The 150,000 psi Hydraulic Intensifier is designed with a ratio of areas on the two pistons of 10 to 1. Consequently, pressures up to 150,000 psi can be achieved by using a commercially available lower pressure (15,000 psi) pump.
Operation of this intensifier is illustrated in the typical installation shown in the schematic on facing page 11.4.
Material of construction for the pressure containing parts is 4340 alloy steel (or equivalent) properly heat treated for use at elevated pressures. Only non-corrosive type fluids should be used. The high pressure packing is housed in a separate removable stuffing box. This design permits improved concentricity and facilitates close tolerance machining of the packing area.
Capacity per stroke at the high pressure end is 1.2 cubic inches. Capacity at the low pressure end is 12.6 cubic inches per stroke. Piston travel is 4 inches.Weight is approximately 150 pounds |
 |
|
Standard connections are for 1/4" O.D. tubing (HF4) on the low pressure end and 3/8" O.D. x 1/16" I.D. tubing (XF6) on the high pressure end. |

| Gas Boosters |
|
|
|
|
The Gas Booster Systems are complete and ready to operate. All that is required is an air supply for the pump (approximately 70 psi) and a commercially available container of compressed gas.
The steel console is 26" wide, 24" deep, 40" high and includes manual valves, air regulator, filter and lubricator, air gauge, high pressure gauge, reservoir, oil filter, pump, gas booster and related high pressure tubing and fittings.
Operation is by means of an air operated hydraulic pump which pressurizes one end of the gas booster which then compresses the gas in the opposite end of the booster. To accomplish this, the gas inlet valve is opened
|
|
|
to permit gas to fill the gas end of the booster. Check valves are provided to permit gas flow in one direction only. With the gas outlet valve open, the hydraulic pump is operated in order to pressurize the hydraulic end of the booster. Thus, the gas is compressed in the booster. If required pressure is not reached by the end of the stroke, the gas booster can easily be recycled for additional strokes.
Note the gauge on these systems is connected to the hydraulic side of the booster. On the Model GBS-30 which has a 1 to 1 ratio, there is a direct reading of the pressure in the gas end of the booster. The Model GBS-60 has a 30 to 1 ratio and the gauge will accordingly indicate a reading of one-thirtieth (1/30) of the actual pressure in the gas end of the booster. An additional gauge can be furnished for connection to the gas end of the booster to provide direct pressure readings of the gas pressure.
Details of the gas boosters are shown on facing page 117.

| High Pressure Generators |
|
|
|
|
The HiP High Pressure Generator is a manually operated piston screw pump. It is designed for any application where a liquid* is to be compressed within a small volume to develop pressure.
Pressure Ranges:
0-5,000 psi l 0-10,000 psi l 0-15,000 psi l 0-30,000 psi l 0-60,000 psi l 0-75,000 psi l 0-100,000 psi
All wetted parts are of 316 stainless steel and 17-4PH stainless steel. Parker Poly Pak® is standard .
The High Pressure Generator is easily mounted to a work bench and maximum pressures may be obtained with a minimum amount of effort
by the operator. The standard connection is a High Pressure coned-and-threaded (HF4) opening for 1/4" O.D. tubing up to 60,000 psi and XF4 connections |
 |
|
for pressures above 60,000 psi. Adapters are available with optional Teflon packing at no additional cost for other type connections including pipe. |
