Note: * The shaft end can be double D and key connection. DN700 and above are double key shaft end. * The table above: Flange connection is DIN2501 PN10 but at the same time, the flange connection can also meet DIN2501 PN16,ASME B16.47-A 125LB/150LB,BS4504,PN10/16,JISB2220 10K. * Please inform us if there is any dimension need to be adjusted. If working pressure is PN16, the shaft diameter is different from the above.
