In honor of those who gave their lives in service to our country, Cornell Pump Company will be closed for Memorial Day, May 25, 2020. We hope you have a wonderful holiday and we will be back on Tuesday, May 26th.
Often, pump maintenance and repairs are done out in the field with no access to shop tools. One of the most common maintenance tasks is replacing the shaft sleeve. Did you know there’s an easy way to remove the shaft sleeve, using only two hammers? This method works so well that it is often preferred over shaft sleeve pullers and other methods inside the Cornell shop!
Keeping one hammer steady on the shaft sleeve, strike the opposite side of the sleeve with the other hammer. Do this along the length of the sleeve, until the sleeve metal is stretched enough to be pulled off by hand. Watch the video to see how quickly and easily this method works!

Many may remember the eruption of Mt. St. Helens on May 18, 1980. Cornell Pump is located about 50 miles from the volcano as the crow flies, and the eruption was fiercely felt and imminently visible for our hometown. During that eruption, 57 people were tragically killed, the mountain blew more than 1,110 feet (335 m) off its top, and 3.9 billion cubic yards (3 billion meters cubed) of debris raced down the mountain into the surrounding landscape, choking off rivers and damming Spirit Lake, on the North flank of the mountain.
Those initial lahars (violent mudflows of earth, ice, snow, and water heated by the volcano) and subsequent smaller eruptions had created a dire situation by 1983. Debris had plugged the lake’s natural drainage and if the “earth dam” had been overrun it would have caused flooding and damage to the recovering towns below, with massive property damage and loss of life possible.
The Army Corp of Engineers called on Cornell to provide pumps that could be shipped very quickly, operate efficiently and reliability, and remove the massive amounts of water needed to reduce the breach risk. Cornell answered with 20 of our 10YB model pumps, removing more than 100,000 GPM—working within a month of the contract award.

A Cyclone VT Series lineshaft turbine (25’ 6RB-75HP Open Lineshaft Turbine) is loaded onto a transport semi for delivery. Cornell offers both enclosed (oil-lubricated) and open (media-lubricated) lineshaft designs in 10 models, with numerous discharge heads combinations, and variable shaft lengths.
Based on our popular RB series of pumps, the Cyclone series is a single bowl short-set turbine ideal for applications in agricultural, municipal, and industrial markets. The Cyclone series meets or exceeds the efficiencies of other manufacturers in configurations offered. Learn more about the Cyclone Vertical Turbine series.
Last week, we looked at poor suction piping; but mistakes can be made on the discharge side as well! The problems in the graphic below are what Cornell has seen most commonly causing piping issues on the discharge side.
We encourage you to thoroughly look at your Operations & Maintenance manual (O&M) that came with your pump—where you can find tips like these, and much more.
Cornell has CD4MCu pumps in stock and ready to ship; 13 of our most popular models are available in this duplex stainless steel. CD4MCu provides enhanced strength and corrosion resistance compared to single phase stainless steel.
If you need pumps with excellent abrasion and corrosion characteristics, contact Cornell today!
Most issues with pump performance occur on the suction side, and many of these are due to poor piping practices.
Here are some common issues that can arise and cause problems:
Last week, we talked about the importance of having your Operations and Maintenance (O&M) Manual handy for maintenance and repair on your pump—those are great times to reference your guide. Another great time though, is when the pump arrives!
The O&M manual will help familiarize you with the pump operation, and importantly should have a checklist of steps that you should follow to ensure the proper and safe operation of the pump. Below is graphic of a generic start-up checklist. These are good general procedures, but your O&M manual will have a list specific to your pump model—and it may be different than what is listed below, as in the case of refrigeration pumps. Refer to your O&M manual for your specific pump.
You should address each of these points to successfully start-up your pump! Be safe in your pump operations.
We hope you are enjoying out Tuesday Tips! Please drop us a line at firstname.lastname@example.org if you have any topics you’d like to see covered.
Cornell Pump’s Co-Pilot Pump monitoring system is receiving rave reviews during this time of limited in-person contact. The new monitoring system allows end-users to check their pump’s operation from thousands of miles away by simply checking an intuitive app or their mobile device or desk top.
Cornell Pump, along with most other manufacturers, send Operation and Maintenance (O&M) manuals out with pumps at the time of purchase. Our manuals are chock-full of good operational ideas and techniques for getting the best performance and longest life out of your rotating equipment. With more than 225 pump models across more than a dozen series, we have a lot of good information and specific manuals for pumps.
In other #TuesdayTips, we’ll delve into specific portions of the manuals, such as when and how to lubricate pumps, start-up best practices, troubleshooting, and more.
For this Tuesday, the tip though is—keep your O&M manual in a place where you easily reference it!
If you have misplaced your manual, you can contact Cornell Pump for a replacement copy. Ideally, we request your pump model and serial number, to get you an exact match for your pump, but we can work with you if you are not able to find that information. You can send requests for manuals through Cornell’s contact form on our website.
Break out your manual to follow along with future tips! (And because it’s a good practice to keep it handy to answer questions as they arise.)
