Performance

Performance curves illustrating Flow (m³/hr and UKGPM) versus Head (metres and feet) are provided for various Engine (Pump) rpm settings (1400, 1600, 1800, 2000, 2200). The curves also indicate minimum and maximum capacity limitations. See the official PDF for exact tabulated values and graphical representations.
