However, pumping in extremely cold conditions, such as near-zero temperatures, comes with its own particular risks. Stefan Hörnschemeyer of Tsurumi Pumps offers practical advice on what to do when the temperature drops.

Groundwater from surroundings as well as rain can flood the whole site if not dealt with properly. When digging below the water table, the amount of water entering the site from the surrounding can be quite large, but this depends on the environment. Ola Hällgren presents an introduction of the role of submersible pumps in controlling the water level. Thu, 05 Mar 2009 00:00:00 GMT http://www.worldpumps.com/view/429/dewatering-a-construction-site-using-submersible-pumps-/ http://www.worldpumps.com/view/430/the-diesel-or-electric-dilemma-/ Until now, the choice between electric-driven or diesel-driven pumps for dewatering applications has not been an even contest. However, rising fuel costs have forced many engineers to re-consider their choice. Here, Roland Berns of BBA Pumps BV argues that in spite of the initial higher purchase price, diesel-driven pumps will pay their costs back many times over in fuel savings.

Production losses due to mechanical failure or higher energy consumption due to lower hydraulic efficiency can be significant factors in the plant operating costs. Miguel Angel Rivas, product portfolio manager for Sulzer Pumps, discusses the options available.

In order for the dosing pumps to work efficiently, works operators need to be constantly aware of what is happening in the treatment process so that dosing levels and speeds can be adjusted accordingly. UK-based Partech Instruments has developed feed forward control systems employing on-line analysers in the inlet stream to send real-time data to a dosing control system for automatic adjustment of the dosing pump.
