In the early 1900s - around the time that naval vessels were first experimenting with diesel engines - another important innovation was emerging at the other end of the propeller shaft line. This ...

PROVIDENCE, R.I. - They are components within a component within a system, but they are critical to the successful creation of cooling. They are shaft seals - seemingly simple items, which are the ...

Wear and leakage are common maintenance problems that result in pump discharge pressure dropping below optimum levels and reduced pump efficiency. Converting pumps to mechanical seals eliminates ...

Shaft seals are used on rotating, reciprocating, and oscillating shafts to contain oil and grease and exclude contaminants. Known as oil or radial lip seals, shaft seals can also contain pressure or ...

As clean-power technologies become more mainstream, offshore and river-based energy generating systems are beginning to come into their own in terms of proven performance. While the sea and rivers are ...

On the face of it, keeping fluids contained seems like a simple job. Your fridge alone probably has a dozen or more trivial examples of liquids being successfully kept where they belong, whether it’s ...

There are various types of mechanical seals, including contacting and non-contacting face seals. They both operate as a sealing system with a stationary component coupled with a matched axial rotating ...

A spring-energized mechanical seal refers to the force used to maintain the seal face and the mating ring in close contact, which is supplied by a mechanical spring device. This device can be a wave ...

In our last installment, we discussed how a shaft seal is just one of a three-part system — a system that also includes the moving shaft itself, as well as the housing into which the seal is installed ...
