Reliability: Avoid pump shaft failures
We welcome and thrive on questions from reliability engineers and try to answer some as best we can.
Compare pitot tube pumps with high-speed centrifugal pumps for low-flow applications
When seeking a pump for a low-flow, high-head application, there is a temptation to choose a high-speed (HS) integral gear-driven centrifugal pump because of its advantages over multi-stage centrifugal and other types of pumps.
Advances in dry gas seal technology for compressors
Compressor owner-operators now have unprecedented and solidly verifiable options.

The FM-approved FireChek thermal shutoff valve with resettable memory shape alloy can now be used to automatically shut down a pneumatic control system when a nearby fire occurs, or when the ambient temperature reaches 135°F, 150°F or 165°F.
HP Reliability: Consider high-pressure throttle bushings made from fluoropolymers
In February 2004, I reported on how horizontal multistage pumps could be upgraded with a high-performance plastic produced by DuPont, Vespel CR-6100.

Ingersoll Rand debuted its TURBO-AIR NX 8000 integrally geared centrifugal compressor at the Turbomachinery & Pump Symposia show in Houston, Texas in September.
Use root cause analysis to examine failure of a cooling water pump
Without a holistic approach and a structured root cause analysis, it is hard to unearth complex and multiple issues, particularly design deficiencies.
HP Innovations
EGC Critical Components has announced its dures brand of materials, a new family of proprietary thermoplastic polymer composites developed specifically for the manufacture of bushings, bearings and wear rings in pumps handling a wide range of liquids, including those that contain solid matter.
