WebDissimilar pumps may be installed in parallel, as well, as long as the pumps have similar shutoff head characteristics and/or are not operated together continuously unless … WebThe pump performance curve shows the correlation between media flow (Q) and the pressure differential or head (H) that the pump creates. The units for Q are normally [m 3 /h] or [l/s] The unit for H is normally [m] H (head) can be recalculated to p (pressure) by using the following equation: p = ρ x g x H [pa] p = pressure [pa] ρ = density [kg/m 3]
WebDec 14, 2012 · The combined H-Q curve in parallel operation is labeled in the figure as two pumps in parallel. At a head of 1200 ft, the capacity of each pump is 1000 gpm. Therefore, in combination, the parallel pumps … WebWhen two or more pumps are arranged in parallel their resulting performance curve is obtained by adding the pumps flow rates at the same head as indicated in the figure below. Centrifugal pumps in parallel are …
WebApr 26, 2008 · The so-called system curve is a parabola in the plane H × Q, which represents the head that must be overcame by the pump, i.e., the static head plus the quadratic flow function system losses.The operating point—the point in which the pump meets the system requirements in terms of head and flow—is obtained by the …
