## Abstract

A double-sided impeller with a dual intake fluid housing apparatus is designed to suction an extraneous fluid through both a first intake and a second intake, where gases trapped in the fluid housing may escape and mitigate cavitation. The apparatus includes a fluid impeller, a fluid housing, an output volute, and a shaft. The fluid impeller is double-sided with a first plurality of blades and a second plurality of blades respectively adjacent to the first intake and the second intake. The fluid housing surrounds the fluid impeller and in fluid communication with the extraneous fluid. The shaft is rotationally coupled with the fluid impeller such that torque applied to the shaft applies torque to the fluid impeller. The output volute is in fluid communication with the fluid housing and tangentially positioned such that the motion of the extraneous fluid in the fluid housing is directed toward the output volute.

## Claims

### Claim 1

A In re application of: comprises:
a fluid impeller;
a fluid housing;
an output volute;
a shaft;
the fluid impeller comprises an impeller body, a first plurality of blades, and a second plurality of blades;
