摘要： The present invention is directed to a pump casing and a centrifugal pump comprising a single piece casing, the casing comprising a first cut-water fluid flow path, a second cut-water fluid flow path, a first joint-water path, a second joint-water path, and an impeller cavity, the first cut-water fluid flow path and the second cut-water fluid flow path communicating with the first joint-water path and the second joint-water path, the pump further comprising an impeller positioned within the cavity, and a suction head overlaying the impeller. The first joint-water path communicates with a first discharge nozzle and the second joint-water path communicates with a second discharge nozzle, the first discharge nozzle and the second discharge nozzle situated substantially at opposing ends of the casing.

摘要： A firefighting pump transmission for use with an emergency vehicle pump comprising a PTO gear affixed to a drive shaft of the transmission and an impeller clutch driving gear affixed to the drive shaft adjacent the PTO gear. The clutch driving gear may couple with a multi-disk clutch to turn an impeller shaft. The transmission allows for changing the gearing of the PTO without affecting the ratio or speeds of the impeller driving mechanism, and vice versa. The dual gears on the drive shaft accommodate compatibility with a Commercially Available PTO device to be mounted to the housing of the transmission to power a variety of devices.
摘要翻译：用于紧急车辆泵的消防泵变速器包括固定到变速器的驱动轴上的PTO齿轮和固定到与PTO齿轮相邻的驱动轴上的叶轮离合器驱动齿轮。离合器驱动齿轮可以与多片离合器连接以转动叶轮轴。该传动装置允许改变PTO的传动装置而不影响叶轮驱动机构的比例或速度，反之亦然。驱动轴上的双齿轮可与市售的PTO设备兼容，以安装到变速箱的外壳上，以便为各种设备供电。

摘要： A firefighting pump transmission for use with an emergency vehicle pump comprising a housing receiving a drive shaft, the drive shaft having a PTO gear affixed thereto within the housing, an impeller shaft for turning an impeller of a pump, and means for selectively powering the impeller shaft from the drive shaft, the means for powering may include a multi-disk clutch. The transmission allows for powering the PTO gear while the impeller shaft is idle. A Commercially Available PTO device may be mounted to the housing to power a variety of devices.
