*1 The maximum supply air pressure for a type with a resin-made pump body will depend on the liquid temperature.
*2 The water discharge is provided as a rough approximation only. The discharge will differ depending on factors such as the liquid to be transferred and the piping conditions.
*3 Maximum flow rate is a value indicating the pump capacity. We recommend selecting a size that allows some leeway, taking into account the impact on the life span of the diaphragm.
