Abstract
A double-seal/oil-reservoir system for motor/pump assembly includes first seal (S1) and a second seal (S2) of a carbon/ceramic ring type that are axially spaced from one another along a drive shaft (24). A containment volume 'V' is defined between the first and second seals (S1 and S2) in which an oil or oil-like fluid is contained to prevent seepage or weepage of the fluid circulated by the pump.
