Centrifugal Pump Alignment

Proper 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.

ITT Research Shows Ozone Oxidation In Wastewater Successfully And Efficiently Treats Endocrine Disrupting Compounds

ITT Corporation , the leading provider of pumps and systems for the movement and treatment of water and wastewater, recently released the results of a comprehensive study showing that ozone oxidation is highly effective for treating micropollutants like Endocrine Disrupting Compounds (EDCs). These potentially threatening substances, such as discarded pharmaceuticals, can be found in municipal wastewater effluents. The results were outlined in a presentation at the North American Regional joint conference of the International Ozone Association (IOA) and International Ultraviolet Association (IUVA) in Boston by Dr. Achim Ried, Director of Research and Development at ITT’s Water and Wastewater business in Germany.

Pump Company offers to reduce pump-operation costs

Pump 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.
