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.
-
Refer to section 5.3 for lubricant capacities and grades.
As standard, the pump is shipped with grease lubricant unless otherwise
specified. The oil filled pumps differ in gearbox construction where
breather, drain plug, and sight glasses are fitted.
-
If an external relief valve is incorporated in the system check that it is set
correctly. For start-up purposes, it is considered a 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
TM 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.
