Pumps for Chinese effluent treatment plants
In August this year, the KSB Group signed a framework agreement covering the supply of pumps and mixers for 52 municipal effluent treatment plants in China. The order is for a total of 335 mixers and 466 wastewater pumps of different types and sizes. Read more »
VSD compressors
With electricity prices set to double over the next few years and the federal government committed to reducing greenhouse gas emissions, buyers of new compressors should assess the energy-efficient benefits of variable speed drive (VSD) air compressors. Read more »
Cam followers and load runners
A cam follower, also known as a track follower or load runner, is a specialised type of roller or needle-bearing roller designed to follow cams. Read more »
Pipeline testing, maintenance and safety
Maintenance of pipelines can be a tricky business. Sealing and testing operations need to be conducted not only with complete safety and environmental security but also with considerable speed, to maintain flows of liquids and gases. Read more »
Contactless transfer of solar cells in production
The production of solar cells involves highly sensitive workpieces, since classical solar cells are just a few millimetres thick. NCT transport units can lift and move these highly sensitive workpieces gently. Even difficult-to-handle materials with sensitive, highly porous or finished surfaces can be moved. Objects are handled using a vacuum - resulting in a non-contact process. Read more »
Cooling water pump for Saudi Arabia
KSB Germany is set to deliver a huge vertical tubular casing pump for an intake structure in Saudi Arabia. Driven by a powerful and energy-efficient 4200 kW synchronous motor, the SEZA 24-160 pump unit will handle more than 16,000 L of seawater per second. The water will be pumped into a piping system to supply Yanbu’s industrial park. Read more »
Protecting pumpsets from rock fall
Sykes Group was recently approached by one of its mining customers to assist in solving an age-old problem - how to avoid damage to pumpsets from rock fallout during blasting. Read more »

Dewatering job in Africa
A quarrying company based in Zambia, Central Africa, contacted Colin Bracken, Sykes group regional manager, Africa, to provide it with a complete solution to its pit dewatering problems. Read more »
Saving energy using valve
Often the work performed by an air cylinder is only required in one direction. During some operations, air cylinders are retracting or extending with no applied load on the cylinder rod - however, typically, the same pressure for both the extend (working) and retract (idling) operation is used. The use of common pressure for both functions can use an excess of up to 40% compressed air. Read more »
Software used in the development of a coupling
Thompson couplings has used Autodesk Inventor software to develop a coupling that addresses a longstanding engineering challenge. The design reduces engineering problems associated with traditional couplings - such as loss of power, vibration, increased wear and machine damage - giving it the potential to benefit a wide range of applications, from truck transmissions to helicopter rotary blades.

Ball screws and nuts
A ball screw is a threaded shaft that provides a spiral raceway for the ball bearings assembled in a nut. This combination provides a precision screw to enable controlled rotational motion to be converted into linear motion. Read more »
Opening an opera house with hydraulic control
With a colourful music program ranging from Richard Wagner to George Gershwin and world premieres of the Norwegian National Ballet, the Oslo Opera House opened in April. The complete electrical and hydraulic control and drive technology, as well as the steel structure for the stage technology, was supplied by Rexroth. Read more »
Hose management
Selecting the right hose to do the job is important for industrial applications, particularly from the viewpoints of suitability, performance and cost effectiveness. Of equal importance is the safe and efficient management of hoses. Read more »
Sustainable compressed air energy savings
As business becomes more aware of its carbon impact and finding ways to reduce its carbon footprint, Boge provides details on a tried and tested four-step approach to energy management for compressed air users. Its approach not only benchmarks an existing system but also provides for continual assessment and validation of the compressed air system. Read more »
