The pumps unique design allows for self priming. To prime,
regulate the air pressure to between 15 psi (1 bar) or lower or
use an air ow regulator to reduce to a slow stroke frequency.
With the high pressure side connected to a vented system, allow
the pump to cycle until a consistent ow of liquid is achieved.
Let the pump ow freely to purge any air in the liquid system.
Loosening the outlet gland or pipe can also assist in priming the
pump.
Increase the air pressure using the air pressure regulator until
you achieve your desired output liquid pressure. At this point
the pump will stall. You can calculate the output pressure by
multiplying the input air supply by the actual pressure ratio of
the pump. The pump will automatically restart if there is a drop
in downstream high pressure.

Parker Autoclave Engineers pumps discussed in this manual are
used for pumping oil, water and oil/water mixtures. Special seals
are also available for chemical service. Please contact Parker
Autoclave Engineers to discuss availability of special seals.
Verify liquid pressure system is protected with
an over pressure relief device.
WARNING
Use an air pressure regulator to assure maximum air
drive pressure listed on the pump label is not
exceeded. An air pressure regulator must also be used to
assure the pump will not exceed maximum liquid output
pressure listed on the pump label.
WARNING
The pump and high pressure liquid system must be
vented prior to installation and start-up.
WARNING
DO NOT exceed the maximum liquid pressure and tem-
perature rating specied on the assembly drawing and
label for your pump. It is recommended to use a liquid
relief valve or rupture disk to prevent over
pressurization of your high pressure system.
DO NOT exceed the maximum air drive pressure listed on
your pump label.
WARNING
Be sure to securely tighten high
pressure tube, pipe or gland with the appropriate torque
after the priming has been achieved.
Reference Tools, Installation, Operation and
Maintenance Manual for tube gland torque value.
WARNING
While testing has shown o-rings to provide satisfactory
service life, actual life will vary widely with differing
service conditions, properties of reactants, pressure and
temperature cycling and age of the o-ring.
FREQUENT INSPECTIONS SHOULD BE MADE
to detect any deterioration and o-rings replaced
as required.

Fig. 7.0 Air Line Schematic
As shown above, a ltered main air supply line is required. The
ltered air supply will go to a pressure regulator which can be
set to achieve the desired output liquid pressure according to the
pressure ratio of the pump.
