Pressure specification
The maximum working pressure of this equipment for fluids and air is 180 psi (12.4 bars) .
Ensure all equipment and accessories used with this pump are rated to withstand the maximum
working pressure of this pump. Never exceed the maximum working pressure of the pump, hose
lines or any other components attached to the pump itself.
Pressure relief procedure
In order to avoid the risk of serious injury to operators from splashing/spraying chemicals, the
following safety procedures should be used. This procedure should be used when shutting down
the pump, performing general maintenance, repairing a pump or other components of the
system, replacing components or when pumping operation is ceased.
1. Close the air valve to the pump.
2. Use the air bleed down valve to relieve the air pressure in the system.
3. Relieve the fluid pressure by holding a grounded metal pail in contact with the metal part
of the fluid dispense valve and slowly opening the valve.
4. With a container ready to catch the fluid, open the drain valve.
5. It is a good practice to leave the drain valve open until it is time to dispense fluid again.
If you are unsure that the fluid pressure has been relieved due to a blockage in a component or
a hose, carefully relieve the pressure by carefully loosening the hose end coupling to allow the
fluid pressure to escape slowly. After the pressure has been relieved, the fitting can then be
removed and any blockages removed. If the pump is to remain idle for only a short period of
time, it is not necessary to empty the wet cup.
Flushing
1. The pump is tested with lightweight oil, which is left in to protect the pump parts. If
the fluid you are pumping may become contaminated by oil, flush oil from pump with a
compatible solvent before use. Follow the flushing instruction below.
2. When pumping fluids that set up or solidify, flush the system with a compatible
solvent as often as necessary to remove build-up of solidified chemicals in the pump or
hoses.
3. If the pump is being used to supply a circulating system, allow the solvent to circulate
through the entire system for at least 30 minutes every 48 hours or more often if
necessary to prevent settling and solidification of chemicals.
4. Once a pump is committed to a particular chemical, it is good practice to identify which
chemical a particular pump is designated for to eliminate the possibility of mix up and
contamination.
