A major oil-tanker operator discovered its existing fuel oil pump system could not meet new environmental regulations for ships entering European ports designated in emission-controlled areas (ECAs).  CIRCOR understood the regulations and responded...

Moving heavy, sand-laden crude oil through its pipelines had always been a tough challenge for a large oil producer located in Venezuela. Because of high levels of basic sediment and water (BSW) in the crude oil, the company’s mainline transfer pumps would gradually lose capacity and require rebuilding every three to four months. These frequent, major repairs resulted in costly downtime, and the company tasked its reliability engineers with finding a solution.

A major Southeastern U.S. electric utility was experiencing excessive maintenance requirements on pumps initially supplied by a competitor for the lubrication (lube) oil system on its General Electric (GE) 7F gas-turbine fleet. Premature failing of the pumps' bearings was determined to be the root cause....

When two separate sewage treatment plants on the border of Germany and Poland decided to combine their operations into a new facility more than 10 years ago, the primary requirement for pumping was clear: create a solution with low Total Cost of Ownership...

The Flerzheim cooperative sewage plant in Germany's Rhine-Ruhr region was looking for a better way to handle raw sludge - and at the same time optimize its operations to cut the facility's energy expenses and maintenance costs...

In August 2014, CIRCOR Fluid Handing Reliability Services was contracted to devise a plan to flush multiple new piping systems on a new tension leg platform under construction in Texas.

For over 40 years, some of the worst conditions in Canada haven’t stopped CIRCOR pipeline pumps.

VT Shipbuilding found itself faced with a complex and cumbersome list of suppliers, including an array of sources for vital pumping equipment. That meant a two-fold challenge: to streamline its supplier list, yet still ensure that the company had quick access to quality pumps...

To maintain their competitiveness in China, the fluids-handling giant needed to reduce their investment in inventory. Alfa Laval needed to serve their Asian customers from Asia. However, Alfa Laval was determined to stay with CIRCOR, due to our product quality and unrivalled client service, and we did not let them down...

Maintenance personnel from a chemical company in Brazil approached CIRCOR’s Reliability Services to discuss contamination problems in the lubrication systems of their centrifugal compressors in their plant ethylene units. Reliability Services conducted a training seminar outlining best practices in flushing procedures and were awarded the contract for Turnaround services due to their extensive experience and vast technical knowledge.
