The common maximum pressure for a hydraulic tensioning pump can range from 700 to 10,000 psi, providing the necessary hydraulic force for tensioning applications.

Hydraulic pumps in tensioning applications typically run intermittently, engaging when tensioning is required and disengaging when the desired tension is achieved. This controlled operation conserves energy and enhances pump longevity.

Hydraulic tensioning focuses on applying tension to bolts, ensuring even and controlled clamping force. Torquing, on the other hand, involves tightening bolts by applying rotational force. Tensioning is preferred for critical joints requiring precise and uniform force distribution.

Hydraulic tensioning is a method of tightening bolts by using hydraulic force to stretch the bolt, ensuring even and controlled tension. It is crucial for applications where precise and uniform clamping force is essential.
