The SP200 to SP600 EC–L series of diaphragm pumps combine novel diaphragm geometries with improved drive characteristics. They can be used in critical areas of analytical and medical technology, in applications that require the alternate pumping of gases and fluids. They offer a dry start-up with large suction heights that is just as reliable in fluid mode as it is when pumping gases. This is an advantage in applications that imply longer drying up phases. The technology allows fora smooth re-start of diaphragm pumps after such dry phases.
