Operating Instruction

3 Pressure tank

A diaphragm pressure tank is used on the discharge side of the pump or pumps to maintain

pressure in the line when there is no demand. This will keep the pumps from continuing to

run. With the Technovar control unit, it is not necessary to have a large tank for supply

purposes.

In selecting a tank, make sure it is permit and suitable for systems pressure. The tank should

have a capacity of more than 10% of the maximum system flow rate g/min of one pump (also

in a multiple pump system!).

Pre charge the tank to the following:

Required pressure

Note:

De-pressurize the tank prior to charging to ensure accuracy of the

pre-charged pressure.
