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.
