The pump delivery (Q) and shaft power (P) curves shown at diagrams are the result of measurements for water at t=293K (20^oC). The purpose of these curves is to ensure comparasion between individual pump sizes only. The optimum pump selection for individual application depends on different factors and must be carried out by our specialists for each case.
