The
Carden universal joint used in this pump is
acknowledged as being far superior to the conventional
single Pin & Bush joint having only contact,
Which is subjected to extreme concentrated load,
resulting in higher wear rate. The Carden type
of universal joint employs two seats of pins
perpendicular to each other, each providing
freedom of angular movement which facilitates
smoother transmission of angular load and also
is designed to better withstand the axial forces,
dominant progressive cavity pumps. |
