美国Yeomans（约曼）9235系列干井潜水泵是固体颗粒污水处理泵，其结构坚固耐用，质量优异，维护成本低，并配置专利技术的闭环冷却系统。这种独特的“CLC” 电机设计不需要外加水保护罩，避免了与“污水冷却”设计所带来的问题。
　　Yeomans Series 9235 dry-pit submersible pumps provide rugged solids-handling pump construction and a quality, low maintenance, patented closed-loop cooling system. The unique “CLC” motor design eliminates the need for external water jackets and the problems associated with “sewage-cooled” designs.

　　*闭环冷却干井潜水电机设计采用专利技术的自动冷却系统。与其它竞争者的设计不同的是，“CLC”系统并不采用内部循环的污水进行冷却，因此就避免了电机过热和冷却通道被堵塞而导致的电机过早损坏。同时，也避免了对冷却通道进行定期的清洗和冲刷。
　　* The Closed-Loop-Cooled dry-pit submersible motor design utilizes a patented cooling self-contained cooling system. Unlike many competitors’ designs, the "CLC" system does not utilize internal circulation of the dirty sewage water for cooling, thereby eliminating motor overheating and premature failure caused by clogged cooling passages. The need for periodic cleaning and flushing of cooling passages is eliminated.
