2. INSTALLATION UNPACKING AND INSPECTION GB-75 and GB-152 are delivered enclosed in plastic film and secured by foam in place in a corrugated box. The Drive Air Control Kit and Interconnections Kit are included in the same box. Remove all parts from the shipping box and plastic bag. Be sure not to lose or discard the Drive Air Control Kit and Interconnections Kit. -
Page 14: Site Requirements
The drive air supply provides power to operate the booster. The booster’s very high pressure output is the drive air multiplied by either 75 (BG-75) or 152 (GB-152). This supply is usually “shop” or “factory” air. Drive air requirements are:... -

Point of use of output pressures; • Noise levels. The booster operation is noisy; • Vibration during use; • Access to the unit for operation of the regulators and valve; • Vents to atmosphere. Page 9 ©1998-2008 DH Instruments, a Fluke Company... -
Page 16: Installation
GB-75™ AND GB-152™ OPERATION AND MAINTENANCE MANUAL 2.3.2 INSTALLATION The installation of the gas booster system is broken down into four parts: • Installation of the gas booster (see Section 2.3.2.1) • Installation and connection of the Drive Air Control Kit (see Section 2.3.2.2) •... -
Page 17: Booster High Pressure Instrument Gas Suppply Connection
Depending on the drive pressure set by the DRIVE ADJUST regulator, GB-75 may generate pressure over 70 MPa (10 000 psi) and GB-152 may generate pressure over 110 MPa (16 000 psi). Be sure to use fittings and tubing rated for the pressure that is to be output from the booster. -
Page 18: Initial Start Up
(75 for GB-75, 152 for GB-152). For example, if the desired high pressure output of a GB-152 is 70 MPa (10 000 psi), set the drive air pressure to 70 MPa/152 = 460 kPa (67 psi). Remember that when the SHUTOFF valve is in the ON position, the booster will operate until the high pressure output is equal to the drive air setting times the booster ratio. -
Page 19: O P E R A T I O
DRIVE ADJUST regulator and the regulator is set to at least 140 kPa (20 psig). Operation is continuous until the outlet pressure is 75 (GB-75) or 152 (GB-152) times the shop drive air pressure. At this point, the opposing forces within the pump reach equilibrium and the pump stalls. For example, using a GB-75 with the drive air pressure set to 500 kPa (73 psig), the pump will run until the high pressure output reaches 75 x 0.5 = 37.5 MPa (5 450 psig). -
Page 20: Setting The Booster Output Pressure
(75 for GB-75, 152 for GB-152). For example, if the desired high pressure output of a GB-152 is 70 MPa (10 000 psi), set the drive air pressure to 70 MPa/152 = 460 kPa (67 psi). Remember that when the SHUTOFF valve is in the ON position, the booster will operate until the high pressure output is equal to the drive air setting times the booster ratio. -

A stalled state will occur when the pressure in the high pressure section of the booster is equal to the pressure in the low pressure section times the ratio (75:1 or 152:1). A stall can only occur if the high pressure circuit is plugged. Page 17 ©1998-2008 DH Instruments, a Fluke Company... -
Page 24: Booster Runs Too Slowly
GB-75™ AND GB-152™ OPERATION AND MAINTENANCE MANUAL BOOSTER RUNS TOO SLOWLY A slow running booster means that the pump itself is running slowly which also causes the pressure to be generated slowly. • Check that the drive air SHUTOFF valve is in the ON position. If not, set the valve fully to the ON position. -
Page 25: Booster Runs (Cycles) Continuously
If the shop drive air supply pressure is above 500 kPa (75 psig) for GB-75 or 250 kPa (40 psig) for GB-152, adjust to below this limit. If the booster stops running, increase high pressure supply to IN port instrument gas supply and try again. -
