3.4 Start Up Procedure.

- Check that all piping and associated equipment are clean and free

from debris and that all pipe connections are secure and leak free.

- For pumps installed with flushed product seals check that all auxiliary

services are in place and connected and provide sufficient flow and

pressure for flushing purposes, refer to product seal section 4.3.

- Ensure lubrication is provided for both pump and drive. RTP

pumps are

shipped without oil. Refer to section 5.3 for lubricant capacities and

grades.

- If an external relief valve is incorporated in the system check that it is set

correctly. For start up purposes it is considered good practice to set the

relief valve lower than the system design pressure. On completion of start

up the relief valve should be reset to the required setting for the

application. The required setting should never exceed the lower of either

the pumps maximum pressure rating or the system design pressure. For

setting integral relief valves, refer to sections 3.8.

- Ensure both suction and discharge valves are fully open, and pipework is

free from all obstructions. RTP

pumps are of the positive displacement

type and should therefore never be operated against a closed valve as this

would result in pressure overload, resulting in damage to the pump and

possibly the system.

- Ensure rotation of the drive shaft is correct for the direction of flow

required, see Fig 7.
