Pumps can be classified in several ways, including by type of fabrication (rotary or reciprocating), case shape (volute or diffuser), impeller shape (open, semi-open, or closed), impeller blade shape (forward, backward, or straight), flow shape (axial, mixed, or radial), and type of use (such as fire pump, dredge pump, or deep well pump). Proper maintenance is important for pumps to function effectively.
