Reduced Pulsations Improve Operation Pulsing, surging flow from traditional metering pumps can produce greater strain on the system and more wear and tear on the pump. Hydra-Cell features a multiple-diaphragm design (except model P100) that practically eliminates pulsations. Reduces pipe strain. Enhances operating safety. Minimizes maintenance. Reduces friction and acceleration losses in the suction line. […]
Manufacturers of variable frequency drives (VFDs) recommend that you perform something called an Auto-tune. Why is that? What is that? It isn’t anything scary or complicated. It simply helps the VFD control the motor with specific motor settings. This document details the importance of performing an auto-tune for your VFD to ensure efficient operation, so […]
The Greening of America’s Buildings The growing green movement has led to a flood of new standards including the US Greens Building Councils Building Performance Initiative, the Green Building Initiative, and LEED — all aimed at increasing energy efficiency and sustainability. Challenged to reduce energy consumption and to document savings, America’s facilities managers are installing […]
Centrifugal and axial compressors are some of the most critical components used within a process plant to handle gases. These machines impart energy to the process fluid, helping to create optimum process conditions while also allowing the transfer of fluid. They typically comprise a major portion of the equipment cost on a project and thus […]
Dan Biby learned it all the hard way. An ordeal concerning several inverter-controlled pump motors with bearing damage made him a believer in the need for shaft grounding. Killer Shaft Voltages Although destructive currents can occur in any motor, they are more common in motors controlled by inverters, also known as variable frequency drives (VFDs). […]
Take Action Today To Improve Your Pump System Are you properly tracking in-feeds, flows, pressure and viscosity, process efficiency and changes to the pumping subsystem over time? Early fault detection based on motor power, along with proper intervention can protect your motors and pumps, improve efficiency, and extend their longevity even in the most dangerous […]
Pumping System Reliability is Critical Pumps and pumping systems account for 25% of the energy consumed by electric motors in the United States. In pumping intensive industries, this number is over 50%. In fact, providing clean drinking water to homes and businesses alone accounts for almost 12.5% of total US pump energy consumption. To improve […]
Reducing energy consumption, costs and emissions in the iron and steel industry The iron and steel industry emits 2.3 Gt of CO2 per year, which amounts to 7% of total global carbon emissions. To meet global climate and energy goals, the IEA estimates that these emissions must be cut by 50% by 2050. This will […]
Variable frequency drives (VFDs) have advanced in capability and function, providing more system control to help eliminate external devices and integrate with programmable logic controllers (PLCs). In most cases, the VFD default settings will be sufficient for your application. If you need to adjust parameter settings, typically no more than a dozen settings are adjusted […]
AEGIS®High-Frequency Ground Strap Ensures Reliable Bond Between Motor Frame and System Ground Reliable-low impedance path to ground for high-frequency currents from the motor frame to drive/facility ground. Improve the grounding system of VFD driven systems plus any attached or coupled equipment. Focus on NEMA and IEC frame motors for off-the-shelf selection in 12” and 24” […]
VFDs Improve Process Control and Reduce Energy Costs According to the American Iron and Steel Institute, energy costs account for 20% of the cost of producing steel. So, by reducing energy consumption, steel plants can increase profitability. By allowing precise control of motor speed, variable frequency drives (VFDs) not only reduce energy costs by 30% […]
