  • Fluid Handling Achieve optimum centrifugal pump performance Food Processing
    Centrifugal process pumps often must perform in hostile and stressful operating conditions. As a result, the likelihood of their premature failure increases over time raising risks of incurring considerable costs and lost productivity from downtime. With pressures mounting to achieve better pump
  • Pump Basics
    The most important characteristic of a centrifugal pump is that of converting energy from a source of motion (the motor) first into speed (or kinetic energy) and then into pressure energy. A pump's role is in fact to confer energy to the pumped liquid (energy later transformed into flow rate
  • When to Use PD Pumps (Copyright Viking Pump, Inc.)
    When to use a centrifugal or a Positive Displacement pump ("PD Pump") is not always a clear choice. To make a good choice between these pump types it is important to understand that these two types of pumps behave very differently. Flow rate versus pressure By looking at the performance chart
  • Applying Inverters to Centrifugal Compressors in HVAC Chillers (.pdf)
    When applying an inverter to centrifugal compressors on HVAC chillers, there are a number of factors to consider. For some compressors, lubricating oil circulation may be driven by the rotation of the compressor shaft itself, via a gear-driven pump arrangement. If you slow the motor speed
  • Adjustable Speed Drives as Applied to Centrifugal Pumps
    . Centrifugal pumps are generally sized to operate at or near the best efficiency point at maximum flow. The maximum flow requirements, however, frequently occur for a very short period during the operating cycle with the result that some method of flow control is required. The traditional approach to flow
  • Pumping Efficiencies Into Oil & Gas
    Efficient, versatile, reliable centrifugal-pump technology can play a crucial role in many applications within the United States' new "Golden Era" of oil-and-gas
  • Controllers with Pump Control
    Surges or pressure transients occur in centrifugal pumping systems when any sudden change of flow is introduced.Electronic starting and stopping of the pump motor will be explored as a cost-effective solution that reduces surges or hammering problems.

  • T-Mag Sealless Pump Solution
    Customer had an existing centrifugal in this application. I was not able to identify it due to the rusted tag. He was looking to use one of our competitor's mag pumps for this application, which would have cost twice as much as the T-Mag Mag Drive Pump. He wanted a sealless pump solution...
  • Putting efficiency into oil and gas
    Centrifugal pump technology can play a crucial role in many applications within the USA's new 'golden era' of oil and gas exploration and production. Focusing on the key areas of saltwater handling and asset transfer, Doug Cumpston discusses the challenges and the solutions offered by Griswold Pump
