NEGATIVE ABSOLUTE PRESSURE IN FLUENT

Greetings everyone! I've got a problem performing simulation of axial water pump: incompressible water, 10000 rpm, pressure inlet, presure outlet, two domains rotor and stator coupled via mixing plane. The matter is that converged solution gives very unusual result: negative absolute pressure at inlet about -100 atm, wich gradualy rises up to 10 atm at pressure outlet. How could negative pressure occur in solver if it is predefined and climed to be positive? Please help me find out the answer on this question!!!!
