II.2 – Reception
Upon receipt of the pump, please check that:
•
The carton has not been damaged in transit. If there is any visible damage, immediately contact
the carrier.
•
The pump is not damaged. If there are signs of damage, you should report this immediately to
SGPPL ASTI or your local distributor.
•
An operating instruction manual has been included in each package. Please request another copy
if it has not been included.
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 “APP 4 EXT”). This drawing also shows the overall dimensions of the pump etc.
The pump must be
installed 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 connections
The pump must be connected to a clean dry air or nitrogen supply. 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 (2 and 5 bar).
For optimum pump operation, we recommend a supply pressure of 58 PSI (4 bar).
The ID of the tube supplying the dry air/nitrogen should not exceed 3/8” (10 mm). The tube length
between the pump and on/off valve should be between minimum 10 feet (3 m) and maximum 19 feet
(6 m).
When in aggressive conditions (acid vapors), it is advised to canalize outlet with a tube minimum
ID 5/8” (15 mm).
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
(see appendix “APP 4 CAB”).
A remote control box with on/off switch and a needle valve (P/N 24 000 04) is available as an optional
extra.
III.3.2 – Fluid connections
The pump is self-priming. The inlet is at the bottom and the outlet at the top.
Two optional fittings are available:
•
PFD4 322
or
PFS4 322
: pump is supplied with flared fittings suitable for 7/8”x1” (22x25 mm)
TEFLON
®
tube. The tube needs to be flared prior to fitting using SGPPL ASTI Forming Tool
(P/N MF12228).
