The R440SS is configured for Clockwise (CW) rotation only. Verify your drive shaft rotation direction before installation. Running the pump in the wrong direction will result in poor performance and premature wear. If your application requires counter-clockwise rotation, see the R660SS or R880SS models in the RollMax series.
