The proper installation of a water ring vacuum pump is critical to its subsequent operation and maintenance.
As with any pump, care should be taken in unpacking the pump so as not to damage or misalign the assembly. For pump and motor units mounted on a baseplate, the unit should be lifted by the base only. Slings or hooks should not be attached to the pump or motor, since this can cause misalignment. Also, the pump should not be run until it is properly installed, nor should it be run without a sealing liquid.
Normally, a pump’s components are protected with a water-soluble preservative, which should be flushed from the unit if any fluid other than water is utilized in a closed-loop system. Pumps made of stainless steel or other non-ferrous materials may be shipped without preservative, that is, “dry.” Finally, the unit should be stored or installed such that any liquid present will not freeze.
