* The maximum pressure that can be applied to the pump under any installation conditions.
** A stored water temperature of 60 oC is considered sufficient to meet all normal requirements and will minimise deposition of scale in hard water areas.
*** A suction lift of up to 4.6 metres can be achieved if a footvalve and strainer is used.
