Niagara brand vibrating-screen exciters (photo) are offered in four models, each of which is adjustable to provide eight weight configurations, delivering a large static-moment range. These exciters come standard on all of this company’s exciter-driven XL-Class and L-Class vibrating screens,…
This company has upgraded its range of SSA actuators for small valves by adding new features for more energy-efficient and versatile hydronic-room applications. The updated SSA actuators now offer more flexibility due to their broad control possibilities — from analog…
The UHF Band RTM (remote tension monitoring) meter (photo) is a wireless bolt-monitoring system that can be used to remotely monitor the tension in critical joints. This wireless sensor detects and collects the tension level in a bolted joint as…
The new Vibrostore 100 (photo) is a palm-sized device that provides vibration-level and bearing-wear monitoring for balance-of-plant machines at the push of a button. The lightweight device can be used single-handedly, and enables even untrained personnel to take vibration measurements…
This column is based on “Acrylonitrile Butadiene Latex Production – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/nitrile-rubber-production-cost. Nitrile rubber (also known as NBR, acrylonitrile butadiene rubber, acrylonitrile butadiene latex, Buna-N) is a synthetic polymer…
This overview compares various sealing technologies, and points out advantages and disadvantages of applying different mechanical-sealing designs for caustic fluids Caustic applications in chemical plants can play havoc on the mechanical seals of rotating equipment. These applications can be difficult…
Waterhammer arises because of sudden changes in fluid flow, and can present significant problems in processes that involve flowing liquids. This article outlines these potential issues and offers guidance for handling the pressure changes arising from waterhammer Most large-scale processes…
Thermal oxidizers are pollution-control units designed to prevent process-generated volatile organic compounds (VOCs) from entering the environment. Different technologies offer tradeoffs among initial cost, operating expense, complexity, emissions, fuel efficiency and destruction efficiency. This one-page reference provides information on selecting…
NanoRam and NanoRam-1064 handheld Raman instruments (photo) are calibrated in compliance with the wavelength accuracy criteria for qualitative Raman measurements set forth by all global pharmacopeias, including the new USP 858 and 1858 chapters. The system software of NanoRam and…
This pictorial guide illustrates some of the common problems that can occur with polymeric and elastomeric materials that differ from those that occur with metallic seals and components Failures of polymer (plastic and elastomeric) parts and their consequences can be…
