• Maintaining performance in older pumps is a balancing act 

  Pumping applications account for more than 20% of global electric motor energy consumption and conscientious plant owners have been trying to maximise the efficiency of this equipment for many years. This task is made more difficult for older equipment for which the full specification data is no longer available or has been re-appropriated for a new task. Jerry Ruc, field engineer with Sulzer, looks at some common causes of poor performance and suggests methods of improving efficiency.

• Energy-reducing sludge solution 

  Progressive cavity pump specialist SEEPEX has developed a new system to improve dewatered sludge handling, enabling long distance transfer with reduced operational costs by using a combination of PC pump technology and dense-phase conveying.

• When three pumps are better than one 

  Engineers at WANNER report they have designed a high flow rate skid that incorporates three of the company’s Hydra-Cell G35 pumps operating in parallel.

• How much will your pump really cost you? 

  When it comes to specifying pumping equipment, many companies, particularly those under increasing pressure to cut costs, could actually be making decisions that will cost them more in the long run. Steve Schofield, director and chief executive of the British Pump Manufacturer’s Association (BPMA), explains how lifecycle costing can help to reveal the true cost of a pump.

• Not too much to ask…. 

  Boulting Technology helped to upgrade Thames Water’s 90 year old Littleton raw water pump station. The water company wanted to increase the performance of the site, while also making it more flexible, reliable and energy efficient. It also wanted to implement an automated system that would speed up pump start-up procedure. Thames water wanted all this without losing any of the pump station’s 1920’s charm! PWE reports.
