Comparing Pump Technologies

For many years, the go-to technology for hygienic manufacturing processes in the food and beverage, pharmaceutical and cosmetic industries have been lobe or external circumferential piston (ECP) pumps and, to a lesser extent, centrifugal, hose and progressive cavity styles. The following chart provides a comparison overview of various pump technologies when taking into account several […]

How to Improve Vertical Turbine Pump Reliability through Optimum Bearing Selection

How to Improve Vertical Turbine Pump Reliability through Optimum Bearing Selection

By Allan BudrisVertical turbine pumps (VTPs) offer many unique advantages for many applications. VTPs are available in deep well, wet pit (short setting or close-coupled), canned, and submersible motor configurations. Accordingly, my September 2008 column on the advantages and cautions of using VTPs on water and wastewater applications concentrated primarily on cavitation, vibration and axial […]
