When the pump load is low and it operates for extended periods at less than 80% of its rated power, it is recommended to use a variable frequency drive. Variable frequency drives are not recommended for vertical pumps, as they can cause the pump to lose its dynamic balance and thus get damaged.

The flow rate and head of the variable-frequency pump are both reduced
