J Line Pump
Horizontal Double Suction Centrifugal Pump – API 610 Process Pump
48 V1.032818
Priming accomplished and correct shaft rotation established, the pump is ready for continued operation.
Therefore, after all the above mentioned items have been considered, the startup procedure is as
follows:
1. Verify that the discharge valve is closed. For high energy pumps, open the discharge valve to
approximately ¼ fully open.
2. Start driver.
3. Completely open the discharge valve IMMEDIATELY when the operating speed has been
reached.
Danger: Do not allow discharge valve to remain closed for any length of time.
Pumped fluid temperature will rise excessively causing damage to pump.
7.3 OPERATING CHECK
During the initial operating hours, the pump should be monitored constantly. So that it is thus possible
to detect irregularities immediately and to take appropriate measures for their elimination (See SECTION
ELEVEN - TROUBLESHOOTING CHART).
As soon as the pump and driver have reached the normal operating temperature, the unit should be
shut down for final coupling alignment.
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 minimum 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.
