Optimizing Pumping Systems
By Robert Asdal, Hydraulic Institute and Pumps Systems Matter

Interest in energy efficiency is not a fad. The economics of industrial production, the limitations of global energy supply and the realities of environmental conservation will be enduring themes for decades, if not the millennia. As energy costs increase, pump manufacturers respond with an understanding of the importance of making equipment more efficient at saving energy.»
Magnetically Driven Pumps: An Overview
By Richard Tym ITT Goulds Pumps

Magnetically driven (mag drive) centrifugal pumps have been in use since 1947 when the first magdrive pump was developed. Mag drives have always been the workhorse pump in applications with corrosive and often toxic fluid applications, and particularly over the last 20 years they’ve become more common in the chemical process industries (CPI).»

Centrifugal Pump Maintenance
Optimal functioning of centrifugal pumps over time depends on sound maintenance practices. The following material represents tips and guidelines for routine preventive and protective maintenance for centrifugal pumps. Monitoring A basic maintenance routine for centrifugal pumps should include monitoring of the following items: Bearing and lubricant condition. Monitor bearing temperatures, lubricant level and vibration. The lubricant should be clear with…

Technology Profile: Isopropanol Production from Propylene

This month's Technology Profile describes a typical indirect propylene-hydration process for the production of isopropanol. In this process, refinery-grade (RG) propylene reacts with sulfuric acid to form isopropyl alcohol sulfates, which are then reacted with water to form isopropanol

Pumping Fundamentals — Volume 2: Operations and Maintenance
Volume two of this two-part series covers many of the strategies employed during pump diagnostics such as vibration analysis, and the steps needed to develop and carry out a condition-based monitoring program. Also included is information to ensure reliable pump operation and efficient, cost-effective maintenance efforts. Several articles are dedicated to lubrication selection and use for all types of pumps. You will find strategies for pumping saline solutions, fluids with high dissolved gas content, hazardous fluids and ultrapure fluids.
