Colfax Fluid Handling has introduced the Allweiler All-Optflow® series of progressing cavity pumps. Applications include waste, wastewater treatment and paper manufacturing. These progressing cavity pumps offer up to 3800 l/min for applications up to 6 bar (87 psi) and move virtually any type of liquid, including fibrous and solid materials efficiently and reliably.
All-Flo Pump Co. announced it’s All-Safe™ DRM (Diaphragm Rupture Management) system to instantly alert pump operators in the event of a diaphragm rupture.
The strictness of demands imposed by legislators and operators on plants and systems employed in the process engineering industry in general and in aseptic process engineering in particular, continue to intensify. Whilst terms such as reliability, availability, life cycle costs, or diagnostic capabilities were used when it came to the characterisation of process pumps previously, cost and energy-efficiency are nowadays increasingly regarded as priority factors.
Covering a wide range of centrifugal pumps for surface and submersible installations, Rovatti pumps are designed and manufactured for potable and industrial water supplies, irrigation, industrial and domestic sewage and waste, drainage, washing, fire fighting and artificial snow making, to name but a few. Among the latest and most significant achievements resulting from the Corporate commitment, it is important to highlight the latest developed production, certainly at the forefront of pumping technology. First of all the enlargement of both AISI 316 casted stainless steel borehole pumps Extreme series and the E series.
The technique of process intensification and micro reaction technology has exceeded the laboratory stage recognizably for some time. Hence, the interest in the practical implementation in production processes for the manufacturing of fine chemicals and pharmaceutical products is high. The associated scale-up requires the adaptation of system components. With regard to metering pumps, this development means the realization of larger dosage volumes and flow rates at consistently high precision. Therefore, HNP Mikrosysteme offers with mzr® 11558 the next size of their hermetic inert pump series of micro annular gear pumps.
The Frankenthal-based pumps and valves manufacturer today publishes its Report on Financial Year 2011. The provisional figures show a new record in sales revenue. In 2011, the KSB Group’s sales revenue increased by 7.2 percent, exceeding the two billion euros mark for the first time. The pump and valve manufacturer achieved a total sales revenue of € 2,079.1 million and posted growth in the three segments – pumps, valves and service – as well as in all four sales regions.
The UK-based specialist pump manufacturer Flotronic already had a solution to aggressive chemicals handling requiring a high flow rate – the Chemflo. The challenge was to produce a cost-effective pump that could handle aggressive chemicals and other products at lower flow rates. The new pump also needed to transfer material at temperatures up to 80°C and be ATEX-compliant and ultra-safe. The turning point in developing a solution came from a simple enquiry. Could a pump be machined out of a solid block of PTFE? And so the ‘Minichem’ was born –a n air-operated double diaphragm pump, machined from one solid block of PTFE.
The need for saving energy meanwhile has been realized everywhere. Economic necessity and political pressure by the EuP Directives have led to the verification of all industrial sectors for energy dissipation and to get it replaced by energy saving solutions. Since pumps are among the major industrial consumers of electricity, here the main activities are concentrated. Pump audits of existing pumping systems have successfully shown spectacular savings of up to 90%. Thus the taken measures do pay for itself quickly. However also negative examples are known where ignorance did lead to misallocation and quite the contrary did occur. For example the simply installation of frequency converters without any analysis of the system conditions does not assure energy savings.
