Applications

Transfer of corrosive liquids, including acid solutions.

Each model is listed with three flow/head duty points. The medium compatibility chart gives liquid-specific temperature limits that may differ from the general operating temperature. Select conditions for the actual medium.

Motor power in the installation drawings can differ from the performance data. Confirm the motor and installation dimensions for the medium density and actual duty point.
