Hydraulic PAMI Air Tensioning Pump

The standard choice, Model PAMI-1500, is specifically calibrated for 1500 bar hydraulic tensioners. The PAMI Air-powered hydraulic pump is engineered as a lightweight, high-performance air power pack, meticulously designed for pressurizing either a single tensioner or smaller sets of tools. It provides an optimal solution that bridges the gap between hand pumps and standard PAXX air pumps by offering the necessary pressure without the excess flow rate. Featuring a 2.4 L tank and a nearly 0.1 L/min flow rate at maximum pressure, this pump proves suitable for a wide array of tensioner applications. Weighing only 15 kg and boasting a compact size, it's effortlessly portable and perfectly suited for applications with limited space constraints.

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.
