Description: h(q) curve for pump where the peak point and shut-off head are not coincidental, or the total head does not continuously decline as the flow rate increases; Name: pump H(Q) curve stable
Description: pump h(q) curve where the maximum head (peak point) and shut-off head are not coincidental, or the total head does not decline continuously as the rate of flow increases; Name: stable pump H(Q) curve
Description: minimum boundary value of the temperature range, in which an operating unit can be used, without serious changes of assigned features, depending on the exposure time. Temporal restrictions like short-time or durability have to be stated; Name: min. temperature range
