Additional Equipment
Additional equipment such as a Power Monitor, Temperature
probe and a Flow meter should be fitted at all times when using
a pump in a potentially explosive atmosphere. The pump / unit
must also be “Earth Grounded” at all times. A pump should
never be “Run Dry” especially in Potentially Explosive
Atmospheres.
General Usage Precautions
1. The pump must be “Earth Grounded” at all times to prevent
Electrostatic charge build up. (When an ATEX approved
pump is requested, a “Ground” contact point is provided
or identified by the protective earth ground symbol.) The
electrical installation must conform to all location relevant
codes.
2. The pump must not be used beyond its ratings and if
the original operating conditions change, it is the users
responsibility to check with the manufacturer to confirm
if the pump is still acceptable for the new operating
conditions.
3. The manufacturer will only consider the pump safe for
the purpose and duty conditions originally specified
by the purchaser. The manufacturer will not accept
responsibility for pump failure or personal injury arising
from misapplication of the product.
4. In the event of any one of the following conditions
occurring the pump should be shut down and the cause
investigated and rectified.
Unaccountable rise in discharge pressure
Release of liquid from the pressure relief mechanism
Excessive noise emissions
Unaccountable rise in operating temperature
Excessive power consumption
Loss of flow
5. Unauthorized modification or use of components other
than original The manufacturer spares revokes any
liability for consequences, which may result.
6. A pressure relief method must be used at the discharge
of the pump to provide over pressure protection. For
ATEX Potentially Explosive Atmospheres, a “return to
tank type piping system” is recommended to prevent high
temperatures due to recycled fluid.
7. Pumps cannot be driven by belts or chains.
8. Lubricate Power Frames if used with the appropriate
lubricant specified in the standard instructions.
9. Check any gear reducers, motor, couplings, etc. for
instructions and lubricate as recommended.
10. Packing should not be used in potentially explosive
environments. Packing adjustment is critical to prevent
high surface temperatures. Packing must leak to cool
itself.
11. Care must be exercised on the initial start of a new pump
to prevent dry running. The pump can not tolerate dry run
for more than a few seconds. Even after initial break in,
pumps must not run dry as high temperatures can happen
very quickly.
12. Inspect the pump for internal wear regularly. Look for
signs of heavy grooving, galling, twisting or breakage.
These are the signs that rapid wear has taken place. This
is a good indication that the pump may not be a good
match for the service conditions. Rapid wear could result
in unexpected failure that could be the source of ignition
of the explosive environment.
13. The purchaser/user must ensure that all maintenance
work including disassembly and reassembly is carried out
by authorized and qualified personnel, who are sufficiently
trained in the operation of the pump.
14. Due to the tight internal tolerances of a gear pump the
most reliable way of repairing a pump is by the use of
a repair kit, which contains all the normal wear parts to
restore the pump to like new condition.
15. Make sure that heavy deposits of dust are not allowed to
accumulate. Clean the pump periodically.
16. Don’t run the pump faster or at a higher pressure than
rated.
17. Don’t flush the pump with steam or air without protecting
against shaft rotation due to the gears in the pump being
forced to turn like a turbine.
18. The use of a power, pressure and temperature monitoring
of the pump and system is highly recommended.
19. Refer to the provided temperature table for information
relating to ambient and fluid temperatures.
20. Properly vent or flush the pump of fluids or gases before
disassembling for service.
21. Obtain, read and keep maintenance instructions furnished
with the pump.
