Diaphragm Pumps

advantages Pumps can run dry for short periods; they are fairly easily cleaned; and they have no glands.

disadvantages Pumps are not reversible; they need valves to operate; and they have pulsing flow.

Mechanical Seals Pumps in the food and beverage industries are almost totally fitted with mechanical seals (see Figure 6). These seals must be simple in construction and designed in such a way as to facilitate cleaning. Cleaning in place (C.I.P.) is a frequent requirement, and mechanical seals for these pumps are specifically designed for this purpose.
