20110142687 | FLOOD WATER REMOVAL SYSTEM - Flood water removal systems including a motor, a vacuum generating device, a discharge pump, and a vacuum tank can be efficiently arranged to be transversely mounted to a vehicle. Certain flood water removal systems can include a supercharger driven by the engine to generate vacuum. The systems can include a valve to prevent collapse of a vacuum tank and maintain a predetermined vacuum pressure without varying the speed of the motor. The systems can also include a two-stage exhaust that blends exhaust from the blower with motor exhaust in a silencer to reduce noise generation for operation in residential or other noise-sensitive settings. The systems can also include a vacuum tank comprising a noise reduction baffle to further reduce noise generation. | 06-16-2011 |
