GB-K Gas Booster Package Operation and Maintenance Manual
This equipment described in this manual is designed and manufactured for the intended purpose of
generating high pressure gas and regulating two independent gas output pressures. Certain precautions
need to be followed during installation and operation of this device. Reading and understanding the
material is essential to the safe and correct operation of the unit.
Pressurized equipment is potentially dangerous. The equipment described in this manual generates and
controls very high gas pressures. It should not be operated by anyone who has not thoroughly familiarized
themselves with this manual. Additional training in general and pressure specific safety procedures will
help assure protection from harm or damage to personnel or property. Responsibility for the proper and
safe operation of this instrument rests with the user.
Do not use oxygen. This instrument is not compatible with the use of oxygen. Hydrocarbon elastomers
and lubricants are present.
High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can
be released unexpectedly and with extreme force. High pressure systems should be assembled and
operated only by personnel who have been instructed in proper safety practices.

1.1 PRODUCT OVERVIEW
GB-K-75 and GB-K-152 are gas booster packages intended to be used to provide the gas pressure
supplies required by DHI PPCK+ controller/calibrators for high pressure gas.
Both models include a pneumatically driven, piston type, self-cycling gas booster with regulated
output to provide the PPCK+ high pressure supply. The gas booster boosts a lower pressure (3.5
MPa minimum), generally supplied from a bottle to higher pressure. The high pressure gas is stored
in an accumulator volume to assure stable supply to the PPCK+. GB-K-75 has a maximum output
pressure of 50 MPa (7 500 psi) and is used with PPCK+ A3000 and A6000. GB-K-152 has a
maximum output of 76 MPa (11 000 psi) and is used with PPCK+ A10000.
Both models also include an independent low pressure regulator and gauge to supply the PPCK+
drive air requirement.
With a GB-K gas booster, all of the PPCK+ pressure supply requirements are taken care of in one
simple package requiring on the connection of a clean gas source of 2 MPa (300 psi) or higher clean
compressed gas source and a shop air supply to power the booster.

PNEUMATIC CONNECTION PANEL:
1. High Pressure Outlet Fitting: a stainless steel DH 200 female coned end fitting used to
connect the high pressure output to a point-of-use (usually the PPCK+ SUPPLY port).
DH200 F is a gland and collar type fitting for coned and left hand threaded 1/4 in. (6.35 mm) OD
tube, equivalent to AE SF250C, HIP LF4, etc. DO NOT USE INCORRECT FITTINGS; DAMAGE TO
THE FITTING AND DANGER TO THE OPERATOR COULD RESULT.
2. Low Pressure Outlet Fitting: a stainless steel 1/8 in. NPT female fitting used to connect the low
pressure output to a point-of-use (usually the PPCK+ DRIVE IN port).
3. Supply Inlet Fitting: a stainless steel 1/8 in. NPT female fitting used to connect an external
source of high pressure gas. This is the gas pressure that will be boosted to obtain very high
pressure at the High Pressure Outlet and regulated to provide low pressure at the Low
Pressure Outlet.

CONTROL PANEL:
4.High Pressure Outlet Gauge: a 4 in. (102 mm) diameter dial gauge constructed of stainless
steel with a range of zero to 70 MPa (10 000 psig) or zero to 103 MPa (15 000 psig). It is used to
indicate the output of the High Pressure Outlet Regulator (7).
5.Low Pressure Outlet Gauge: a 2 in. (51 mm) diameter dial gauge constructed of stainless steel
with a range of zero to 300 psig (2 MPa). It is used to indicate the output of the Low Pressure
Outlet Regulator (12).
6.Pneumatically Operated Gas Booster Pump: a Pascal press utilizing two pistons connected
together on the same axis having a nominal area ratio of either 75:1 or 152:1. The booster is a
two-stroke, single stage reciprocating pump.
7.High Pressure Outlet Regulator: a self-venting type regulator constructed of 303 stainless
steel, Kel-F, Buna-N, and Teflon wetted materials with an outlet pressure control range of 1.5
MPa (200 psi) to 50 MPa (7 500 psig) or 76 MPa (11 000 psig).
8. Shop Drive Air Inlet Fitting: a brass fitting with a 1/4 in. NPT female connection.
9. Shop Drive Air Pressure Gauge: a 1.5 in. (38 mm) diameter dial gauge constructed of brass
with a range of zero to 1.4 MPa (200 psig). It is used to indicate the output pressure of the Shop
Drive Air Regulator (10).
10.Shop Drive Air Regulator: a self-venting type regulator constructed of 316 stainless steel and
nylon wetted components with an outlet pressure control range of 0.9 MPa (125 psig).
Maximum supply pressure is 1 MPa (150 psig). The control knob is pulled out to make
adjustments; pushed in to lock into position. To prevent accidental pressure changes the knob
can easily be removed (pulled off).
11.Shop Drive Air Shut-off Valve: a brass ball-type, shut-off valve with a 90° full turn operation.
It is used to prevent flow of shop drive air to the booster. This valves turns the booster on and
off.

stainless steel and Nylatron wetted materials with an outlet pressure control range of 0.15 to
1.25 MPa (20 to 180 psig). Maximum pressure supply is 20 MPa (3 000 psig).
