Super Jenny Hydraulic Semi-Automatic Tube Puller

KRAIS Tube Expanders

Key Features

Our Super Jenny Series of Hydraulic Semi-Automatic Tube Pullers, allows the user to continuously pull tubes through heat exchangers, condensers and boilers, without the use of hammers or winches etc. The key to our system is the OD gripping jaw that will pull the tube as the operator actuates the ram. To release the jaw, the operator simply inserts the jaw release tool and the tube becomes free to be pulled by hand, or the ram is returned against the tube sheet to take another stroke. All of our pulling heads work in conjunction with our specially designed high flow electric or pneumatic power packs.

The three pulling head series, allows the user, the flexibility of removing tubes from 3/8” – 2” OD through the ram with 4” OD stub pulling capability.

Our smallest, the “Mini-Jenny”, has been specifically designed for chiller and condenser work. Weighing in at just 18 lbs. (6 kg), this 10-ton capacity ram can pull up to 1” OD tubes. With a 3” stroke, this unit is exception- ally quick, and is ideal for tight access applications.

Our 30-ton “Super-Jenny” is the workhorse of our industry. Available with either a 3” or 6” stroke, this tool is capable of pulling 5/8” – 1-1/4” tubes continuously. It can even pull up to 3” stubs in specific applications.

Our 60-ton “Super- Jenny” has been designed to pull tubes in the tough- est applications. As standard, the unit can pull 1 1⁄2”-2” tubes. As a special, an adapter is offered which will allow the operator to pull smaller diameter tubes with up to 60 tons of pulling force.

For example, a tube extraction of 1 1⁄4” x 10 BWG with a 7” tube sheet was noted to pull at 52 tons of pulling force.
