The vertical extended shaft single stage centrifugal pump occupies an important place within the pumping industry. It performs as no other pump can, the function of transferring Iiquid from below ground reservoirs or enclosed tanks. While the vertical pump is not necessarily expensive, its design is in many ways more critical than those of more common centrifugal pumping units. Attention must be paid to pump operating speeds, bearing arrangements, shaft design and construction. This bulletin illustrates, to the customer, how this pump will contribute to the solution of complex pumping applications.
