Pneumatics or Hydraulics

Pneumatics or Hydraulics Both pneumatics and hydraulics are applications of fluid power. Pneumatics uses an easily compressible gas such as air or a suitable pure gas—while hydraulics uses relatively incompressible liquid media such as oil. Most industrial pneumatic applications use pressures of about 80 to 100 psi. Hydraulics applications commonly use from 1,000 to 5,000 psi but…

Shore Hardness

Shore Hardness or Durometer is one of several measures of the hardness of a material. Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert Ferdinand Shore who developed a device to measure Shore hardness in the 1920s. The term durometer is often used to refer to the measurement as…

O Ring Material Issues

O-Ring Material Issues. Recently, we shared the three most common O-Ring design flaws. By identifying potential problems like insufficient gland volume, high tolerance levels and over compression, engineers can resolve potential O-Ring issues before they happen. Choosing the proper material is as crucial to the success of an O-Ring as the design. Key questions must be…

O Ring History

O Ring History The first patent for the O-ring, is dated May 12, 1896 as a Swedish patent. J O Lundberg  the inventor of the O-ring, received the patent. The US patent  for the O-ring was filed in 1937 by a then 72-year-old Danish born machinist,  Niels Christensen. Soon after emigrating to the USA in 1891, he patented…

Global nitrile butadiene rubber market set for rapid growth

Market News Global nitrile butadiene rubber market set for rapid growth, to reach around £346 million by 2020 according to a new research report. Nitrile-butadiene rubber is a complex family of various butadiene monomers and unsaturated copolymers. Its chemical and physical properties vary based on the polymer’s composition of nitrile. This form of synthetic rubber is…

For Water and Wastewater Pumps

Because mechanical shaft seal failures are the number one cause of pump downtime, it was decided to dedicate this  to mechanical seal basics. Years ago, most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate…

Mechanical Seals

Main elements of a mechanical seals All mechanical seals are constructed with the following basic sets of parts: A set of (very flat) machined and lapped primary sealing faces: The very close (near) contact between these two flat mating surfaces, which are perpendicular to the shaft, minimizes leakage. Dissimilar materials are usually used for the…
