3.3.1 Expansion Tank
The expansion tank, included in a standard pump package, has an internal volume of 8.8gal.(33l) and a maximum pressure
of 100psi(690kPa).
The tank is sized for a typical “open” system with a fluid volume of less than 75gal.(280l). When used in a “closed” system,
volumes of up to 140gal.(530l) can be accommodated. We recommend use of a field-supplied safety-relief valve for
systems “closed” to atmospheric venting. Other piping accessories for filling, venting, or adjusting the fluid in the system,
are recommended, but not included.
