In this chapter, we introduce the components in the centrifugal pump and
a range of the pump types produced by Grundfos. This chapter provides the
reader with a basic understanding of the principles of the centrifugal pump
and pump terminology.
The centrifugal pump is the most used pump type in the world. The principle
is simple, well-described and thoroughly tested, and the pump is robust, effective
and relatively inexpensive to produce. There is a wide range of variations
based on the principle of the centrifugal pump and consisting of the
same basic hydraulic parts. The majority of pumps produced by Grundfos
are centrifugal pumps.
