INSTALLATION, OPERATION, AND MAINTENANCE
Safety notices – General Safety Rules – Symbols
(danger-warning-caution)
DO NOT
exceed the pumps rated pressure, speed, and temperature, or change the system/duty
parameters from those the pump was originally supplied, without confirming its suitability for the
new service.
BEFORE
operating the pump, be sure that:
• It is clean and free from debris
• All valves in the suction and discharge pipelines are fully opened.
• All piping connected to the pump is fully supported and correctly aligned with the pump.
• Pump rotation is correct for the desired direction of flow.
INSTALL
pressure gauges/sensors next to the pump suction and discharge connections to
monitor pressures.
USE
extreme caution when lifting the pump. Suitable lifting devices should be used
when appropriate.
DO NOT
attempt to dismantle a pressure relief valve that has not had the spring pressure
relieved or is mounted on a pump that is operating.
AVOID
contact with hot areas of the pump and/or drive. Certain operating conditions,
temperature control devices, improper installation, improper operation, and improper
maintenance can all cause high temperatures on the pump and/or drive.
THE PUMP
must be provided with pressure protection. This may be provided through a
relief valve mounted directly on the pump. Relief valve adjusting screw caps must always
point towards suction side of the pump.
THE PUMP
must be installed in a matter that allows safe access for routine maintenance and
for inspection during operation to check for leakage and monitor pump operation.
