First super-low specific-speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low; Secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. Therefore the H ~ Q characteristic curve is often hump-shaped, and at the low-capacity operating condition the instability often occurs; Thirdly the centrifugal pump at high-capacity operating condition is easy to overload because the N ~ Q curve appears a rising trend.

首先由于它的扬程较高、流量较小，所以它的流道狭长，圆盘摩擦损失较大，效率相对较低；其次由于它的流道扩散较严重，易在叶片进口产生回流和在出口产生脱流，扬程流量特性曲线易出现驼峰，在小流量工况下易产生不稳定现象；第三，由于其功率流量曲线呈现上升趋势，在大流量区运行时电机易过载。

One more word of caution. Always check Everything. Transits, progressions, solar arcs. And check them to midpoints as well. I had a client who didn't want a complete reading, just her solar return chart. All she was interested in was where to be on her next birthday so she could get a better job.
