When a US wastewater treatment plant in South Carolina saw lower flows than expected, due to a delayed housing project, the facility experienced repeated vapour lock resulting in higher operational and chemical costs. The manual dilution operation resulted in increased operational and chemical costs, so a solution was sought in Grundfos' digital dosing technology.

Energy savings can be obtained in several ways, but before manufacturers turn to hydraulic optimisation of units or apply new electrical drives or powerful control systems, they should look at the dimensions of the pipelines and make sure they get the duty point specifications right. This can be done with the aid of web-based tools from Vogel Software.

Frothing and breakdowns were regular occurrences for printer Portishead Press as their air-operated diaphragm pump and its seals could not cope with the caustic coating solution used by the printer. The company needed a pump that could move the coating fluid quickly, without introducing air, so they looked at a Watson-Marlow close coupled peristaltic pump to provide the answer.

Brazil is known for its use of hydropower, but when a small, remote tourism complex in a Brazilian nature reserve needed additional power supply, a conventional hydropower solution was deemed too expensive. A more affordable option came in the form of a KSB centrifugal pump driving an electric motor acting as a generator.

Pumps represent a significant target for energy savings. The need to measure, monitor and manage consumption is viewed as an integral part of all process systems. Here, Jack Creamer from Schneider demonstrates that a process energy optimization approach can allow energy consumption to be analysed and managed, giving potential efficiency gains of up to 30%.

Horizontal drilling and hydraulic fracturing technologies grant access to natural gas encased in shale formations. However, this is just the start of overcoming challenges associated with a shale well’s 20 plus year life expectancy. New diaphragm pump technology from Neptune Pump Company is providing solutions to the harsh realities of shale well production.

At the heart of any hydraulic system, pumps are exposed to severe wear by running at high revolutions over extended periods of time, often handling high temperatures and pressures. Today, some of the latest lubrication science is creating even greater benefits from this often-forgotten component, says Shell's Mark Draper.
