The full motor horsepower is translated into fow via the shaft. These pumps are used for a wide range of applications, from chemical transfer to process solution recirculation to waste treatment. This series is capable of self-priming up ro 20 feet of lift. The mechanical seal is a self-cooling, Tefon bellows which is cooled by the solution being pumped. The construction materials and seals avaiable make this pump extremely versatile. The horizontal design has a working temperature from167℉ to 194℉(75℃ to 90℃), depending on the material of construction, and can handle most chemical solutions. The SD/LD/SL series pumps are designed to run outside the tank or process module. The SD/LD series pumps incorporate a FRPP molded base, legs and pump-to-motor casing. There are no bolts or metallic parts in contact with the solution being pumped.

SD/LD/SL泵是可靠的自吸泵，马达全部的马力经由轴心完全转化为流量，此型泵广泛地使用於从化学药水循环或加工溶液循环到废水处理等各种用途，此型泵可自吸达20英呎，机械轴封是自我冷却的，经由抽送的溶液来冷却，可供应的不同结构材质及轴封使此种泵的用途非常多样化，依其结构材料的不同，其卧式设计的工作温度由75℃到90℃(167℉到194℉)，而且可处理绝大部份的各种溶液，SD/LD/SL是设计用於槽外或加工模组之用，SD/LD加入一个FRPP射出成型的脚座，脚架及泵到马达的外罩，没有螺栓或金属会接触到所抽送的溶液。

You're in the batter's box when the 6-ft., 1 in. pitcher unleashes a bundle of blonde fury: whippet arm windmilling across the mound, ball screaming toward the plate at some 65 m.p.h. Because of the short, 40-ft. mound distance in softball, that's like trying to hit a 90 m.p.h. pitch in baseball. Swing and a miss.

当你在击球区看着一位六尺一英寸的投手释放出金色美女的激情：她轻盈的臂膀在投手土墩（mound：投手所站在的小高地）旋转，球以65英里/小时的速度呼啸着向垒板而来，因为垒球中土墩距离只有40英里，65英里/小时速度这棒球里相当于90英里/小时。
