SM Diaphragm coupling

Series SM diaphragm coupling is another metallic flexible coupling which adopts German production technique. It uses the flexible elements that are connected through independent chain plates. The chain plate is 2-8mm high strength alloy steel plate. The installation and replacement are convenient. The performance and use range are basically as same as Series JM diaphragm coupling. It has obtained wide application in fields like mine, cement machinery, iron & steel, fan and pump, etc.
