Method and apparatus for increasing performance of a pump

An improved pump of the type having a pump impeller, wherein the improvement comprises:

• an impeller disk having a plurality of impeller disk blades attached on top of the pump impeller such that a total number of blades used by the pump is increased and liquid flow rate is increased and wherein interior edges of the impeller disk blades are located such that when the impeller disk is attached on top of the impeller of the pump the interior edges of the blades contact the impeller of the pump to prevent rotation of the impeller disk and lock the-impeller disk blades.

An improved pump of the type having a pump impeller, wherein the improvement comprises:

• an impeller disk attached on top of the pump impeller such that a total number of blades used by the pump is increased and liquid flow rate is increased;
• and
• an anticavitation disk attached on top of the impeller disk.

A method for improving the liquid flow rate of a pump comprising the step of attaching an impeller disk on top of an existing impeller of the pump such that a total number of blades used by the pump is increased and liquid flow rate is thereby increased.

A method for improving the liquid flow rate of a pump comprising the steps of:

• attaching an impeller disk on top of an existing impeller of the pump such that a total number of blades used by the pump is increased and liquid flow rate is thereby increased;
• and
• attaching an anticavitation disk on top of the impeller disk.

A pump performance disk kit comprising:

• an impeller disk;
• and
• a plurality of impeller disk blades extending at angles from a planar surface of the impeller disk such that when the impeller disk is attached on a planar surface of an existing inner pump impeller the impeller disk blades extend axially from the impeller disk in the direction of the inner existing pump impeller and a total number of blades for use by a pump is increased and wherein the interior edges of the impeller disk blades are located such that when the impeller disk is attached on top of the inner pump impeller the interior edges of the blades contact the inner pump impeller to prevent rotation of the impeller disk and lock the impeller disk blades.

An improved pump of the type having a pump impeller, wherein the improvement comprises:

• an impeller disk attached on a planar surface of an existing inner pump impeller wherein blades of the impeller disk extend axially from the impeller disk in the direction of the inner existing pump impeller such that a total number of blades used by the pump is increased and wherein the interior edges of the impeller disk blades are located such that when the impeller disk is attached on top of the inner pump impeller the interior edges of the blades contact the inner pump impeller to prevent rotation of the impeller disk and lock the impeller disk blades.

A method for improving the performance of a pump comprising the step of:

• providing the pump having an existing inner pump impeller;
• and attaching an impeller disk on a planar surface of the existing inner pump impeller wherein blades of the impeller disk extend axially from the impeller disk in the direction of the inner existing pump impeller such that a total number of blades used by the pump is increased.
