Many EASA service centers have installed facilities for operational testing of pumps. Equipping a pump test facility for variable speed operation can provide greater flexibility and expand opportunities to evaluate pump performance. For close coupled pumps (integral pump-motor units), a variable frequency drive is all that’s needed. If an independent motor is required for testing, other variable speed options such as clutches and DC motors will also work.
