Abstract
Provided is a progressive cavity pump. The progressive cavity pump operates such that a viscous liquid is discharged by rotating an eccentric rotor with respect to a stator. The progressive cavity pump may be easily disassembled for repair and maintenance, and may be easily attached to an accurate position during re-assembly. Also, in the progressive cavity pump, main components such as a nozzle, a rotor, a stator, etc. may be easily replaced so as to easily adjust dispensing characteristic, while the driving units such as a motor and a rotary shaft are installed in a dispenser, and thus, an idle time of the dispenser may be reduced.
