Consider more than curves when choosing a pump
WebMaximum Suction Lift Affecting the Total Suction Head is the Maximum Suction Lift, which is the height from which a pump can “pull” water. This number is impacted by atmospheric pressure and friction in the system. (The terms “pull” or “suck” are misleading. The atmospheric pressure actually “pushes” the fluid into the vacuum. Web2 Feb 2024 · TDH is the pressure to push water through a system. The suction lift requires the least energy, the pressure boost requires the most, and friction loss varies according to pipe size. It's important to remember that this equation only calculates static head loss, which does not include pump power consumption or gravity head. feels like the first time song
