Horizontal End Suction Pump for Chemical Process, ASME B73.1-2001
Installation, Operation, and Maintenance Manual – CPP21
The startup procedure is as follows:
1. Before starting the pump, check the security of all bolting, piping, and wiring.
2. Check all gauges, valves and instruments for proper working order.
3. Check all equipment for proper lubrication and correct rotation.
4. Open and look through the oil fill/breather (refer to General Arrangement) to verify that the oil rings are
in their grooves (oil ring and purge mist lubrication only).
5. Verify that the discharge valve is closed.
6. Open the suction valve.
7. Open discharge valve and allow pump to fill with fluid (pump is self-venting).
8. Keep the valves open approximately 60 seconds to ensure that pump is completely full of fluid.
9. Close discharge valve.
10. Uncouple the driver and the pump.
11. Start, and IMMEDIATELY STOP, the driver and observe the rotation of the shaft.
12. Correct rotation should be in direction of rotation arrow.
• If shaft rotation is incorrect, consult driver manufacturer's instructions in order
to change rotation.
13. Priming accomplished and correct shaft rotation established, the pump is ready for continued operation.
14. Securely couple the driver and the pump, and ensure the discharge valve is open to approximately ¼
fully open.
15. Start driver again, and 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. It is thus possible to detect
irregularities immediately and to take appropriate measures for their elimination (See
SECTION ELEVEN -
TROUBLESHOOTING CHART).
