Precise pump dimensioning

Often a detailed dimensioning of the pump can be avoided with help from the quick dimensioning. When in doubt, the required pumping capacity should be determined more accurately. For this purpose, the following steps explain the selection of a suitable pump according to DIN 1988, Part 3 and 5<ref name="DIN1988">DIN 1988 Teil 3 u. 5</ref>. The required pumping capacity depends on the type of supplied fixture as well as the piping system. The pump must provide the calculated flow rate, Q, at the necessary pressure, herein described as discharge head, H. The flow rate results from the operating values of the fixtures, which should be simultaneously operated. The necessary pressure is composed of three parts:
