Bearing isolators 101
A bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized, so that they dont separate from one another while in use. Typically, the rotor turns with a rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in.
Technology expands flowmeter capabilities, reduces costs
Capacitance-type magnetic flowmeters have traditionally offered the advantage of having non-wetted electrodes and the ability to measure low conductivity fluids. However, they suffered from a sensitivity to flow noise and zero instability. Innovative technology overcomes these limitations and drives magnetic flowmeters into new areas of application, while reducing installed costs.
Electro-hydraulic system design: Making the right system choices
Designers who understand and can take advantage of the differences between fluid power and traditional electromechanical power can build machines that produce higher quality output with lower lifecycle costs. This white paper suggests that care must be taken, however, in selecting and sizing the hydraulic system elements and in tuning the motion controller for optimal performance.

Accurate liquid phase density on aerated liquids
This white paper discusses SONAR-based, clamp-on gas volume fraction meters which recently have been introduced to the industry that provide an accurate, real time, measurement of entrained gases. Coupling entrained gas volume fraction monitor with most types of process density meters, enables accurate determination of liquid and the liquid-solid components of aerated mixtures.

Design Considerations for High Liquid Rate Tray Applications
Except for a few odd services, high liquid rate applications are typically the domain of either trays or random packings. Aside from the distributors, random packing designs are rather straightforward with the designer choosing the proper size to accommodate the fluid flow rates and achieve the desired efficiency. Trays, on the other hand, have a large variety of adjustable parameters and can be especially complex, especially when designed for high liquid rate applications.
Case Study: How can manufacturers ensure they are choosing the right heat transfer fluid
Reliable heat transfer fluids are vital to the ability of manufacturers to operate efficiently and productively. However, some heat transfer fluids can degrade over time, resulting in deteriorating performance, impacting operating costs and product quality. With these possible consequences, how can manufacturers ensure they are choosing the right heat transfer fluid, and prevent these problems from occurring?
Closed System Technology Drives the Trend Toward Safer, More Cost-Efficient Chemical Dispensing
In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container.
The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.

Special Report -- Control With Flow
With changes in temperature, pressure, density and viscosity all affecting volumetric flowmeter measurement, how can continuous processors accurately measure the flow of fluids? Download this Special Report to find out how Coriolis flowmeters provide a direct mass measurement that is unaffected by changing process fluid characteristics improving both accuracy and optimizing operations at your plant.
Spray Gas Quench Design Considerations
The use of spray nozzles to rapidly cool or quench gas streams is an essential application in many industrial processes, such as chemical reaction vessels, incineration, and power plant absorber gas inlet. An optimized spray quench design requires engineering analysis of the operating environment, spray nozzle performance and process reliability.
This technical paper describes the design considerations for spray gas quench systems such as nozzle selection, process control, system configuration and reliability. Application of this knowledge can result in a gas quench system that operates efficiently and reliably with reduced vessel size, reduced atomization energy consumption, and minimized downtime, to achieve capital and operational cost savings for your process.
Chemical and Pharmaceutical Sight Glass Application Handbook
20-page Sight Glass Application Handbook is a convenient reference for experienced engineers and a great primer for those new to sight glass selection. It offers a full overview of sight glasses for chemical processes, including types of glass, construction, lighting, installation and maintenance.
Not All CPVC Piping Systems Perform The Same
Since its introduction to the market in 1959 by The Lubrizol Corp., chlorinated polyvinyl chloride (better known as CPVC) has proven to be an attractive alternative to traditional metallic piping systems in a wide variety of chemical process environments. Because it is inert to most mineral acids, bases, salts and aliphatic hydrocarbons, it offers a more reliable, long-term performance than many other materials, including metals and most non-metallic alternatives.
This white paper will explain why Lubrizol's newly developed Corzan CPVC Piping Systems are pressure rated 25% higher than traditional CPVC systems. Download now.
