* 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.
*** *** With footvalve fitted.
Although these pumps are self priming we recommend a footvalve/strainer is used if a suction lift is required.
