3.4.2 Installations with CIP Systems.
The Revolution pump range is designed to be effectively cleaned by the CIP
procedures recommended for in place cleaning of process plants. It is
recommended that a differential pressure of 2 to 3 Bar (30 to 45 psi) be
developed across the pump head during cleaning in order to develop the
necessary fluid velocities required for thorough cleaning.
To assist in maximizing the effectiveness of cleaning within the pump head, it is
recommended that during the cleaning cycle a flow rate equivalent to a velocity of
1.5 metres per second in a pipe of equal diameter to the rotor case connections is
achieved. In a pump with a 2.5 inch port, this means 300 litres per minute (for the
R800).
We also recommend rotating the pump during the CIP cycle to help the flow enter
all cavities.
3.5 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 fitted with flushed product seals check all auxiliary services are in
place and connected and provide sufficient flow and pressure for flushing
purposes.
-
Ensure lubrication is provided for both pump and drive. The Revolution can
be shipped with different lubrications see section 6.3 for 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.
-
Be sure both suction and discharge valves are fully opened and that pipe
work is free from all obstructions. The Revolution is a positive displacement
type pump 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.
-
Make sure that the drive shaft rotation is correct for the direction of flow
required. See Fig 8.
