20150021901 | GUIDE LINER FOR BREAK-AWAY FITTING - A break-away fitting facilitates installation and removal of a pump in wet well system, along at least one guide rail. When installed, the fitting mates an outlet of the pump to an outlet pipe of to wet well. The fitting has a body with a first and a second surface, the surfaces arranged to be substantially perpendicular to each other. A flanged opening in the first surface is sized and adapted for attaching the body to the outlet flange of the pump. The second surface has indentations for engaging the at least one guide rail, so that the body slides in the vertical channel. To minimize the dangers from static electricity in the wet well, the body may be formed from a non-sparking material, such as brass or bronze, or a surface of the indentations may be covered by a non-sparking material, including high-density polyethylene or poly(tetrafluoroethylene). | 01-22-2015 |
20100099286 | MULTI-VOLTAGE PUMP WITH DISCREET VOLTAGE CORDS - A device for interfacing power from an electrical supply having power terminals, that permits implementation of a wide range of power cord lengths and voltage connection combinations. The device includes a body having a cord side and an appliance side. The body has four or more terminals located on the cord side of the body, with one terminal being a ground terminal. At least one electrical connecting device is adapted to connect terminals. In a first configuration, the device is used at a lower voltage. In a second configuration, the device is used at a higher voltage. | 04-22-2010 |
