Dura Products announces the availability of its Universal Pump Hold Down System (Patent Pending) which allows a conventional reciprocating rod pump or rotational progressive cavity pump (PCP) to be installed interchangeably into the same seating nipple. This feature makes the product particularly well suited for thermal production where operators may have a need to change the pump type as the well’s temperature profile changes during steam injection or production. The system can be configured for either top or bottom hold down configuration as required.
For either pump type the installation is very simple – set down to install, and straight pull to retrieve – no additional manipulation of the rod string being required. The axial force can be adjusted to suit the application.
The design can be easily customized for any given tubing diameter, allowing full selective nipple I.D. and is suitable for deviated wellbores and sour environments.
The design features a one piece nipple and inner mandrel with field proven metal-to-metal seals. The hold down mechanism has been carefully designed to provide reliable operation and release in the presence of sand and other solids.
The 4-1/2" size has been torque tested to 5,000 lb.ft
