PUMPWORLD

The technical magazine on pumps and pump issues by Worthington.

These articles were produced by the Worthington pump company 35 years ago. The company is no longer in business and at one point was bought out by Floserve. I am not sure if Floserve still sell the Worthington pump brand.

The articles have been made available to me by a friend that used to work for Worthington in Western Canada. I believe he felt that it woulds a shame for these very well done articles to disappear. So he recovered them and sent to me.

In the past I have contacted Floserve to get permission to re-print some of their material without ever being able to get an answer. If they ever contact me regarding these articles I hope they will grant permission to make these available, so in the mean time, enjoy…..
