Abstract
The present invention relates to a fluid handling system including a collection trough and pump assembly. A centrifugal pump is mounted in the path of cutting fluid that needs to be pumped from a collection system and discharged. A wide and narrow inlet mouth lies very low on the factory floor enabling the centrifugal pump to be mounted right on the floor and not within the floor. An optional vacuum system provides suction within the centrifugal pump that aids in priming the pump at start up and in removing air from a pump chamber within the pump, thus allowing more efficient pumping to take place. An impeller rotates within the pump creating a vortex within the pump chamber which facilitates movement of dirty cutting fluid including metal particles to be pumped through to a discharge outlet.
