Vertical Process Pump

DANGER: Do not allow discharge valve to remain closed for any length of time.
Pumped fluid temperature will rise excessively causing damage to pump.
Only if your pump will operate submerged in a sump or well, the discharge
valve may be left opened since installation and during the startup procedure.
7.3 OPERATING CHECK
During the initial operating hours, the pump should be monitored constantly. It is thus possible to
detect irregularities immediately and to take appropriate measures for their elimination (See
SECTION ELEVEN - TROUBLESHOOTING CHART).
To monitor flow, pressure, temperature, and lubrication, regular visual inspection and monitoring is
advisable and/or necessary during operation.
Ruhrpumpen recommends checking the pump constantly at regular intervals in order to detect
problems early, in case they arise.
The operational check routine must include at least the following points:
Beware of freely rotating parts, when the pump is in operation there is a high
risk of injury.
• Check at regular intervals that the safety equipment is sound and is arranged and fastened
according to the regulations, and energized where applicable.
• Check the security of all bolting, piping, and wiring.
• Check all gauges, valves, and instruments for proper working order.
• Check all equipment for proper lubrication and correct rotation.
• Check the oil level and validate that the correct oil grade is installed.
• Check that the pumping unit is running quietly and without vibrating.
Unusual or too loud noises point towards a possible fault.
