Witryna17 gru 2011 · The upper curve shows pump head with the ring clearance reduced to 0.004 in. (To operate with such a small clearance, special casing rings were designed that are free to float and align themselves with the impeller rings.) With the tighter rings, the head increased about 20 ft (3 percent). Witryna17 gru 2011 · For typical process pumps, reducing wear ring clearance by 50 percent will produce an efficiency gain in the range of 2 to 4 percent. The exact gain will be related to the pump's specific speed, the pump type, how much the clearance can be reduced and where the pump operates on the curve.
