“The hermetically sealed centrifugal pump outperforms magnetic-drive pumps with respect to mode of operation and reliable contents of solids and gases in the pumping medium” — the verdict of PROCESS on a new magnetic-drive pump. That was over two and a half years ago, so its now time to find out how the dry-running horizontal pump has fared in day-to-day service.

Many industrial processes require heat energy to be moved from one place to another via a heat transfer fluid: typically water and steam at temperatures up to 200 °C, and heat transfer oils for the range 200–450 °C. Pumping fluids reliably at such high temperatures is a challenge that sealless canned motor pumps can meet. The new generation of solar thermal power stations provides a practical example.

Microbiologists, biochemists, and chemical engineers need to cultivate organisms in a highly controlled manner. As such, bioreactors have become integral to the pharmaceutical, food, and chemical industries. In order to successfully fulfill experimental requirements, suitable conditions and parameters must be provided, which include accurate temperature control, i.e., heating and cooling.

Asynt has recently announced its new flow-chemistry platform, the fReactor, an affordable device created to bring the many advantages of flow chemistry to one’s laboratory through easy-to-use, flexible and intuitive design.

They are made to work everywhere and still vary widely in size and application: fittings that ensure safety in the oil and gas industries, channel fluids through chemical plants, control the supply and drainage of water, gas or highly corrosive media or regulate the correct flow in the beverage industry.

The EU’s revised Machinery Directive 2006/42/EC specifies that machine controls should be designed to ensure that they do not present hazards. This requirement is not new — it also appeared in the previous (1998) version of the Directive — but what is new is how this safety is to be achieved. Engineers dealing with mechanical design and plant construction are now caught between two new safety standards, EN ISO 13849 and EN IEC 61508, both of which require quantitative risk analysis.

The Vortab Company offers Vortab Elbow Flow Conditioner that eliminates the problem by removing swirl and asymmetric velocity profiles caused by pumps placed too close to the meter. This helps Wastewater treatment engineers find room for the recommended straight pipe run needed by electromagnetic flow meters in sewage lift stations.

Flowserve supplies newly developed, custom-engineered, reactor recycle pumps for DuPont's new IsoTherming–process. The Flowserve pumps are designed to operate at the high pressures and temperatures required in the process, while maximizing availability and providing high mean time between repair (MTBR), the company says.

When considering a pneumatic conveying system, the simple purchase price is no longer the most important business criterion. Today, and especially in the chemical industry, the analysis of costs and benefits goes far deeper: More important than a supposedly low purchase price are total cost of ownership and overall equipment effectiveness — especially when dealing with the transfer of powders and bulk materials.

In line with its goal ‘Higher output with the same quality and safety’, CP Pumpen has launched a new pump size in its established MKP product range of sealless magnetic drive pumps. With this new pump size, it is now possible to transfer hazardous media at higher flow rates using the efficient, rugged and safe magnetic drive pumps from CP.
