ALTEK
PRECISION VACUUM PUMP - MODEL 618V PRECISION PRESSURE PUMP - MODEL 618P
OUTPUT RANGE:
   Model  618P - Pressure: 145 PSIG/10 BAR
   Model  618V - Vacuum:  600 mm/23 Hg
PRESSURE CONNECTIONS:
  Single 1/8 NPT Female Fitting
SIZE:
  Body Diameter:  1.5/3.8 cm
  Length:  8.5/21.6 cm (collapsed)
  11.5/29.2 cm (extended) Generate pressure or vacuum where you need
it with either Altek’s Model 618P (Pressure) or
Model 618V (Vacuum) Pump.
The pumps are tube type, cylindrical shaped
hand pumps with a “T” handle at the compressor
end and a round knob at the volume adjust end.
The overall length is between 11.5 (full extension)
and 8.5 (fully collapsed). They incorporate a
needle valve for venting and a volume adjust
vernier for precision adjustment of pressure.Pressure or vacuum connections  are made
through one 1/8 NPT internally threaded fitting.
The pump is small in size, lightweight and
ruggedly constructed to withstand typical field
use. Model 618’s simple design and quality
construction ensure a long service life.
Every technician can carry one in their toolbox
and be ready to go.

							CONNECTIONS
To install a pressure fitting in the Model 618:
1) Turn the BLEED VALVE counterclockwise to bleed any pressure
2) Use a 5/8 open-end wrench on the input port to prevent it from rotating
while tightening the supply fitting with a 5/8 open-end wrench.
LEAK PREVENTION AND DETECTION
In order to obtain maximum pressure indication stability, leaks
must be avoided. It is strongly recommended that either
Teflon
® tape or commercial pipe sealant be used at all tapered
fittings and connections. If Teflon® tape is used, care must be
taken that the proper amount is applied. Excessive tape may
fray and cause plugging of relief valves, orifices, nozzles, etc.
Overuse of pipe sealant may cause similar problems.
External equipment should also be checked carefully for leaks.
Process connections, flange bolts, and vents must be tightly
closed. Defective gaskets, leaking valves, and damaged
diaphragms are all potential sources of leaks.
For detection of very small system leaks, the traditional soap
bubble method may not be sufficient. Halogen leak detection
devices may be required when using highly sensitive pressure
calibration equipment.
TEMPERATURE CONSIDERATIONS
Since the pressure change of a contained volume of gas is directly
proportional to absolute temperature, temperature control is
critical when using the Model 618 with any high-resolution mea-
suring device. Tubing should be kept away from heat sources (i.e.,
lamps, operating electronic equipment, excessive hand contact,
etc.) as well as from heat-dissipating structures (i.e., open win-
dows, air conditioning vents, etc.) to minimize temperature varia-
tions that might induce errors.
Air is compressed by the Model 618. This compression causes
some heating of the air as it is forced into the system.  Consequently,
a noticeable decrease in pressure—caused by the cooling of the
newly compressed air—may occur immediately after cessation of
pumping.

OPERARTING INSTRUCTIONS
PRODUCING PRESSURE
1) Connect Model 618’s port to the instrument to be
calibrated or checked.  Use small-diameter tubing as
short in length as possible (this will maximize the
pressure adjustment range).
2) Set the FINE ADJUST knob to the full
counterclockwise position.
3) Turn the BLEED VALVE knob fully counterclockwise
to relieve all system pressure and zero any measuring
devices.
4) Turn the BLEED VALVE knob fully clockwise to
close.
5) Repeatedly move the T handle in and out to generate
the desired pressure.
6) Use the FINE ADJUST knob to bring up the pressure
to the precise level.
7) Use the BLEED VALVE to lower the pressure from he
pressure generated. Opening the BLEED VLAVE 
1/4turn will lower the pressure very gradually. Opening
it 1/2 turn will release the pressure faster and opening
it 3/4 turn will quickly and safely release all the pressure
in the system.
WARNING
It is imperative that all system pressure is relieved prior
to making any connections or disconnections. Failure to
relieve system pressure could result in serious personal
injury or equipment damage. Even nominal pressure
values can generate extreme force if fitting or tubing
failure occurs due to improper installation or usage.
Since the Model 618 is capable of generating pressures
exceeding 100 psig, it is important that all pressure
connections and test procedures be done by qualified
service personnel, according to standard engineering
practices, to prevent possible personal injury or
equipment damage.
