Zusammenfassung:	A progressive cavity pump comprises a sealed drive part between a rotor and a universal joint. The universal joint includes a socket configured to receive a drive shaft of the rotor. A cover, such as a lock nut, is disposed over the connection portion between the rotor and the universal joint. A seal is held in place by the lock nut to prevent abrasive material from entering the interface between the rotor and the universal joint. 전진 공동 펌프가 회전자와 유니버설 조인트 사이의 밀봉된 구동부를 포함한다. 유니버설 조인트는 회전자의 구동 샤프트를 수용하도록 구성된 소켓을 포함한다. 잠금 너트와 같은 커버가 회전자와 유니버설 조인트 사이의 연결부 위에 배치된다. 시일이 잠금 너트에 의해 적소에 유지되어 연마 재료가 회전자와 유니버설 조인트 사이의 계면으로 진입하는 것을 방지한다.
