Centrifugal Pump Alignment
Posted on June 10th, 2009 No commentsProper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability. For appropriate applications, the time, expertise and instruments needed to achieve precision alignment (tolerances of less than 0.005 in) will prevent seal leakage and extend bearing life. Depending on such factors as operating speed and coupling type, not all pumps will require such precise alignment. When assessing a plant’s alignment needs, it helps to understand basic shaft alignment concepts and procedures, as well as application-specific factors that dictate the required tolerances.

Dean Pump’s pH Series ANSI design chemical process pumps
Posted on May 23rd, 2009 No comments
Experience Counts! In 1958, Dean Pump’s pH Series was the benchmark used in developing the ANSI/ASME B73.1 process pump standard. The pumps continue to meet and exceed all ANSI standards for the chemical processing industry. Dean Pump’s pH Series centrifugal process pumps are designed to insure long, continuous service life at low cost. Dean pumps are manufactured in our state-of-the-art facility in Indianapolis, Indiana. A choice of ductile iron or 316SS construction, coupled with multiple seal design types, allows us to quickly custom build your pH pump to suit virtually any process application. Our ready to ship factory inventory, along with a network of factory-trained and authorized distributors, allows us to offer you a 48-hour commitment on pH pump shipments, with NO PREMIUM! This commitment, and our outstanding technical support, enables us to respond to your process pump needs with the utmost urgency. -
Watson-Marlow aids Enpure
Posted on May 17th, 2009 No commentsWatson-Marlow peristaltic pumps are being used by Enpure to feed samples of filtered clean water onto a turbidimeter, enabling continual turbidity measurement. Turbidity measurement helps operators of municipal water-treatment plants ensure a high quality of drinking water and provides continual monitoring to detect the presence of the water-born parasite cryptosporidium bacteria.

New Lowara circulators pump range
Posted on May 15th, 2009 No commentsITT Lowara’s new range of wet rotor circulators for handling water in heating, air-conditioning and domestic hot water circuits are used in both residential and commercial applications. The use of alternative energy, such as solar and geothermal power, has been introduced with the new TCLSOL and TLCK models. The variable speed versions feature an automatic rotation speed adjustment system that allows power demands to be adapted to system requirements. The use of permanent magnet motors puts this range in energy class A, thus strongly reducing consumption.

DULCOflex pump series at Achema
Posted on May 15th, 2009 No commentsThe Heidelberg-based ProMinent will present the peristaltic pumps of the DULCOflex series for the first time at Achema 2009 in Hall 8, Stand D2-E6. Because of their large output range of 17 to 25,000l/h and the large number of different hose materials, applications in laboratories as well as in industry can be implemented. The peristaltic pumps are self-priming, without gaskets and valves. While the pumps for low pressures of up to 8bar are equipped with roller technology, sliding blocks are used for higher pressures of up to 16bar. The main advantages offered by the peristaltic pumps are their ability to gently deliver and to suction dry. Pasty and solid-containing media as well as viscous, abrasive, corrosive or outgassing media can be delivered. The delivered medium comes only in contact with the hose. These series can be equipped with a vacuum device on customer request. This device supports the restoration of the hose’s shape. The suction behaviour is thus improved and provides for a steady delivery of viscous media.

Performance Curves and NPSH Tests for centrifugal pump
Posted on May 14th, 2009 No comments
NPSHR Shown as a Single Line as a Function of Capacity Only. Figure 1 is an example of single‑line performance characteristics of a centrifugal pump. The independent variable capacity is plotted on the horizontal scale. Power, head, efficiency and NPSHR are plotted on vertical scales-each as a function of capacity. Read the rest of this entry » -
Pump Company offers to reduce pump-operation costs
Posted on May 12th, 2009 No commentsPump Company is offering variable-speed drives and efficient motors that can help reduce the cost of pump operation by between 30 and 50 per cent. Traditional methods of throttling oversized pumps result in wasted energy and high costs, whereas a variable-speed drive ensures that no more energy than necessary is used to achieve the required result.

Larox Flowsys introduces lower cost model
Posted on May 11th, 2009 No commentsAccording to Larox Flowsys, while the existing version offers multiple automatic input/output control and alarm modes, the new basic version will have only single manual output control mode. Technical features such as the flow rate, pressure and suction lift remain, but the facility to programme remote adjustment and different feedback signals are omitted from the basic model.
