III – Installation and Operation
III.1 – Testing
All pumps are tested with DI water at the factory in our clean room for:
•
Maximum flow rate with no back pressure,
•
Minimum flow rate with no back pressure,
•
Flow rate with 58 PSI (4 bar) discharge pressure,
•
Checked for leakage.
III.2 – Set up
The pump must be installed
horizontally
as shown on general arrangement drawing (see appendix).
This drawing also shows the overall dimensions of the pump etc.
The pump must be
positioned on its feet
. If not, the check valves will not seat correctly and the
pump may malfunction.
III.3 – Connections
III.3.1 – Air/Nitrogen connection
The pump must be connected to a clean dry air or nitrogen supply (in compliance with ISO 8573-1).
On no account should the air/nitrogen supply be lubricated, oil or water droplets will cause the shuttle
valve to malfunction.
Minimum and maximum supply pressure must be between 29 and 72.5 PSI or 2 and 5 bar (please
contact us for different values).
The ID of the tube supplying the dry air/nitrogen should not exceed 5/16"x3/8" or 8x10 mm. The tube
length between the pump and the air pressure regulator should not exceed 10 feet or 3 meters
maximum.
When in aggressive conditions (acid vapors), it is advised to canalize outlet with a tube of minimum
ID 3/8"x1/2" or 10x13 mm, and a length of maximum 3 meters (do not add any muffler at the tube
end).
The pneumatic on/off valve must be 3-way to ensure the shuttle valve on the pump resets itself when
the pump is switched off. The flow control valve must be positioned before the 3-way on/off valve
and you must preserve the values of flow air which you can find on the flowrate curve in appendix.
