Refer to the performance curve for proper pump selection to prevent overheating from low flow or motor overload from excessive flow.

Installation Requirements

Environmental Considerations

For operation above 40°C ambient temperature or above 1000m elevation, motor power may need adjustment due to reduced cooling efficiency at lower air density.

Minimum Inlet Pressure

To prevent cavitation, ensure adequate inlet pressure using the formula: H = Pb×10.2 - NPSH - Hf - Hv - Hs, where Pb is barometric pressure, NPSH is Net Positive Suction Head, Hf is inlet pipe loss, Hv is vaporization pressure, and Hs is safety margin (minimum 0.5m).
