Peristaltic pump tackles troublesome pH at Greencore
Food manufacturer Greencore is reporting "significant savings" in downtime and repair costs on water treatment plant at its site in Selby, North Yorkshire, thanks to a high pressure peristaltic hose pump.
Peristaltics take on the nasties
Surface treatment technologies specialist AHC Benelux reports that its peristaltic pump is working well, handling aggressive wastewater fluids.
Plant life matters
Although the cost of components - such as rolling element bearings, rotors and fasteners - in hydraulic pumps is usually very small, compared to the list price of the pumps themselves, the cost of stopped production and any consequential losses resulting from component failure is almost invariably significant.

Pump primer
On average, each of us drives past around 1,000 pumps on our daily commute to work. That's all types, including pumps installed in process plants, industrial facilities, construction sites, HVAC equipment - you name it. But wherever and whatever they are, this crude statistic reminds us of the sheer variety of pumping duties, and pump types and sizes. Which should make it all the more surprising that so many of us stick to a type, even down to the manufacturer, we know, and rarely question whether there might be something better.
Pump suction
Selecting a pump is always about balancing several factors - for example, the volumes and contents to be pumped, the efficiency required and how frequently the pump will be run. But where space is at a premium, or the cost of changing process the liquid structures or pipework is prohibitive, may be a cocktail of plant engineers may also have to deal chemicals, meaning with an additional factor - namely the vapour pressure poor suction static head. Failure to take may need to be this into account can cause cavitation, determined with catastrophic consequences.

Choosing the right pump can be hit-and-miss, as plant engineers seek to escape issues such as over-sizing and over-engineering. Steed Webzell investigates
Pumping challenge
Engineering invariably involves a balancing act - mostly between, on the one hand, keeping within budget, while, on the other, developing robust, dependable solutions that meet parameters, such as design life and risk mitigation.

The vast majority of pumps and fans could be running more efficiently and saving their plant operators serious money. Brian Tinham examines equipment advances and cautionary tales
