Booster Pump Application- Control Guide
In Instead of using a large closed pressure tank, one or more pumps
together with an open storage tank will maintain constant static pressure
in the system. If the system pressure exceeds the allowable level, a relief
valve will lead the water back to the tank. It is recommended that treated
water be used.
The set point will be the static pressure of the system.
It is recommendable always to install a standby pump. If the system is
used for refilling the system please note that there is a risk of cavitation
in the pump when the system pressure is very low. To avoid this the flow
from the pump has to to be throttled down
