GRAPHALLOY, a graphite-metal alloy manufactured only by Graphite Metallizing Corporation, has long been used to provide reliability when pumping low-specific-gravity fluids or when “run dry” conditions occur. Successful applications include heater drain and condensate hotwell services in electric generating power stations, stripper pumps on barges, and light hydrocarbons pumps at hot, ambient, and cryogenic temperatures […]
Cavitation prevention and protection is an important consideration in the design and operation of valves used in water distribution systems. One should be able to determine if cavitation exists, and if so its intensity and effects on the system. Cavitation in valves is a destructive condition that seriously affects the operation and service of the […]
Challenge At a paper plant, a critical hydrate slurry pump with a high concentration solids had infrequent high vibration which posed a threat to equipment reliability. The vibration expert could take only point-in-time measurements and was unable to detect when the vibration reached at its maximum. Download this whitepaper to find out how Chesterton Connect™ […]
An air-operated double diaphragm pump is a very reliable pump type and certainly very easy to operate and maintain. Nevertheless, there are a number of things that allow you to “kill” your pump. 1. Run the pump dry without limitations 2. Run the pump with dirty and/or very humid air 3. Start-up of the pump […]
1. Examine– Visually examine and clean flanges, bolts, nuts, and washers and make sure to replace any defective components, if necessary. 2. Lubricate– Lubricate bolt threads, nut threads & facing, and washers 3. Install– Install new gasket (Do not reuse old gaskets or use multiple gaskets). Download this whitepaper from Durlon to learn the 8 […]
Backflow is the result of water flowing in the reverse or unwanted direction. This generally happens when the normal supply or upstream pressure in a pipe drops below the downstream pressure, allowing contaminated water to get drawn in the opposite direction of the usual water flow. Not only is it inconvenient, but it can also […]
The technology used to produce metering pumps has barely changed in over a generation. As a result, conventional metering pumps have operational limitations and greater cost consequences. Hydra-Cell is not a conventional metering pump. Hydra-Cell Metering Solutions pumps enable you to meet and, in most cases, exceed API 675 performance standards with linear, virtually pulse-free […]
You have bought a pump, or you are considering a purchase. Perhaps you experience problems with the pumps in your mining process. In all cases, it might be worth taking a few moments to read our tips. What do I expect from this pump? What pumps are right for my process? Is the temperature consistent […]
Pump failure is an expensive problem. Not only does it cost money to have the pump repaired, but there is also the loss of productivity and the resulting impact on the business which has suffered the failure. Following the failures of two Worthington 10-stage split case diffuser style pumps, engineers at a hot strip mill […]

By Brooke Winner and Jacque Boudreau Evolving Waste Stream The modern waste stream is continuously increasing in solids content. In recent years, wastewater professionals have witnessed unprecedented growth in flushable wipes being deposited and accumulating in the waste stream. The consumer and industrial wipes market was estimated around $2.1 billion in 2018 and is expected […]
