What is life of diaphragm?
Life of diaphragm depends upon liquid to be handled and cannot be specified. But in case of our pump we have done some innovative improvisation. We have put diaphragm movement limits on link that connects diaphragm to handle. This prevents overstretching of diaphragm on upper and lower end of stroke. Overstretching is one of the major reasons for diaphragm breakage, and that factor is fully taken care of.
