Pump
Cavitation
To prevent cavitation:
Make sure the pump is appropriate for the installation
On a variable speed pump, make sure the setting is correct – a slower
speed that still has enough head pressure is best, as it will minimise the
pressure difference at the pump.
Mount the pump as low as possible relative to the tank, so the water
pressure from the tank feeding in to the pump is maximised.
Lower the resistance to water flow to the pump (use wider – at least ½ “
diameter pipes; reduce the number and ‘sharpness’ of s-bends, etc)
If cavitation at the pump remains a problem, you may need to consider:
Installing a larger pump with a larger impellor to reduce the vacuum at
the impellor
Converting the system to mains pressure
