Seal Replacement Video

Cornell’s new instructional video explains how to replace a seal on a pump with a threaded impeller. Useful in manure, as well as some industrial and mining applications, the video can be viewed in conjunction with many of the other instructional videos on Cornell Pump’s YouTube channel.  We cover a range of topics, from replacing wear rings, changing bearings on refrigeration pumps, how to install packing and lantern rings, pulling impellers, and more.

If you have a Cornell Pump maintenance topic you’d like to see covered in a video, please let us know;  e-mail  We’re shooting new videos every month!

Cornell Self Primers Work Well in Tomato Trash Wash



Cornell self-priming pumps replaced electrical submersibles in a tomato processing plant. The pumps are used in the trash wash phase, where tomatoes are cleaned prior to being processed. This wastewater stream carries leaves, grit, dirt; stems, and other materials.

The electric submersibles were unreliable, often failing, and backing up the wastewater into the facility. Given the need to expeditiously process the tomatoes in the short growing season, the delays were very costly to the plant.

The Cornell 6-inch self-primers worked flawlessly.

Cornell Pump in Kentucky

Cornell Pump, in conjunction with our distributor Endesol, is in Lexington, Kentucky for a regional Pump School.

Dozens of engineers and water operators are learning about municipal applications today.

To see an expanded school offering, check out our annual Pump School in September.

Signaling the Future

Cornell Pump has new, illuminated signs on our building. Featuring the Cornell Pump logo, company name, and tag line Efficient By Design, the new signs replace signs that had been installed when Cornell moved into the building in 1999.

The signs  glow with halo LEDs at night, making Cornell Pump more noticeable and easier to find in the long Oregon winter.  They also look sharp, with an architectural flair.

You can see the Cornell Pump factory in Clackamas, Oregon. If you attend our annual pump school, you can come inside for a tour!

Wednesday March 14 – National Potato Chip Day

Crinkly, chunky, BBQ, salt & vinegar—there are many ways to enjoy potato chips. Cornell Pump helps in the irrigation, hydro transport, and frying of America’s number one snack food.

Facts about National Potato Chip Day:

  • Chips are rumored to have started in 1853 in Saratoga, NY.  A picky restaurant patron kept sending back his potatoes as too thick and limp. The cook cut the spuds as thin as possible and fried them until crisp—rather than complain, the customer loved them. What we know as potato chips, were called Saratoga Chips and appeared on area menus in the 1850’s.
  • In the early 20th century, chips were packaged as a snack food.
  • Flavored chips appeared in the 1950’s.
  • Chips are over a $15 Billion a year industry.

For information about hydro transport pumps and hot oil pumps, such as those used in making potato chips, download the Cornell Food Processing Pumps Brochure.

Enjoy some potato chips today—which is also National Pie Day in honor of 3.14; the first three digits of Pi π. (You can google a potato chip chocolate pie and have the best of both national days….)

SP Series is Sweet in Hawaiian Sugar Plant

Much Better Up Time and $50K Flush Water Cost savings per year

A sugar cane producer in Hawaii was having issues with previously installed slurry pumps, transporting wastewater through a production plant. The liquid was abrasive, and the customer used rubber-lined slurry pumps to deal with the sugar’s and plant fiber material’s tendency to scour the inside of the pump.

The installed pumps needed frequently maintenance/service shutdowns, and required flush water for the seals. For the application, the specific gravity of the sugar slurry was 1.05%, the TDH was 60’, the operational RPM was 470, and flow was 4,900 GPM.
Cornell Pump suggested our 10SP series because the customer preferred to stay with a slurry pump. The SP comes in metal and rubber-lined, 2”-12” discharge. Cornell suggested the metal liner to better deal with the abrasion. With the specific gravity and percentage of solids in the application, Cornell’s MP or N series pumps in hardened material could have also handled the slurry.

Three 10 SPs were installed in 2014, and a fourth was held on standby. The spare was never used, even though the 10 SP’s ran 24 hours a day, every day. The seals were not replaced, because they never leaked.

The Cornell 10SP pumps delivered an estimated $12,000 a year in saved maintenance. An even bigger cost savings accrued to the plant by not requiring flush water. A typical 10” pump needs about eight gallons a minute of flush water for a mechanical seal. At 0.004 cents a gallons (average US price per gallon of municipally supplied water) that may not seem expensive. Eight gallons a minute run 24 hours a day, is 4.2 million gallons of flush water, at an average cost of $16,800 a pump per year. The three pumps saved over $50,000 a year in flush water costs.
The pumps operated for a little over two years, and save the producer over $130,000 in operational costs. The plant ended up shutting down, because of overall world sugar prices.

Pumps provided to the sugar plant:

  • Four 10SP Cornell Cycloseal® slurry pumps.
  • Frame mounted with 150HP-1200rpm motors.
  • Cast iron housings
  • Chrome iron liner with chrome impeller
  • Chrome iron back plate with Cycloseal®
  • 150HP 230/460 volt, 1200 rpm TEFC motor
  • Steel overhead motor base with belts, shives, and guard.
  • 2 year warranty

Cornell at SME February 25-28

Visit Cornell Pump at the Society for Mining Engineers (SME) show in Minneapolis, MN. We’re in booth #1027.  We’ll be showcasing or SP,MP, and SM slurry lines for difficult mining applications. You can learn more about our mining products here.

Show runs Sunday, February 25 through Wednesday February 28, 2018.

Happy National Almond Day!

Cornell Pump supports National Almond Day on February 16, 2018!  Many of our pumps aid almond growers in California. According to the Almond Board of California, more than 130 million trees produced about 1.8 billion pounds of almonds in 2016. The 6,800 almond farmers grew nuts for the U.S., along with 90 other countries, and the economic impact was about $11 billion in California.

Whether you grab a handful of roasted almonds as a snack, enjoy them in the Northwest’s own Almond Roca®, or sprinkle them on a salad, we hope you get to partake in tasty almonds today.

Cornell Pump is grateful to connect with farmers and ranchers everywhere to supply robust, high efficiency pumps for irrigation, dewatering, and manure handling needs.    You can see our irrigation and manure pumps here:
