ABSTRACT:
The instant invention is a self-adjusting blade insert used for improving the efficiency of low rotating disc pumps by use of pivotal disc inserts disposed between the rotating discs of a multi-disc pump turbine style pump causing a positive displacement of fluid during the low rotating conditions or low viscosity fluid environment. The blade inserts of the instant invention include a biasing spring which allows the blade inserts to pivot outward when sufficient hydraulic pressure creates force against a lower surface of the blade inserts allowing maximum flow at higher rotations or predetermined operating conditions.
