Summary:A progressive cavity pump includes a sealed drive 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 locking nut, is disposed over the connection between the rotor and universal joint. Seals are retained in place by the locking nut to prevent abrasive materials from entering into the interface between the rotor and the universal joint. 渐进腔式泵包括在转子与万向节之间的密封驱动。所述万向节包括被配置成接收所述转子的驱动轴的插口。盖(诸如，锁紧螺帽)被设置在所述转子与万向节之间的连接上。密封件被所述锁紧螺帽保持在适当的位置，以防止磨料进入所述转子与所述万向节之间的接口中。
