valves, or pump speed adjustments. The most efficient of these is pump speed con-trol. When a pump’s speed is reduced, less energy is imparted to the fluid and less energy needs to be throttled or bypassed. Speed can be controlled in a number of ways, with the most popular type of variable speed drive (VSD) being the variable frequency drive …
The value of VSDs in improving efficiency – Plant Engineering
Energy efficiency: Using drives to control motors can lead to big savings Nearly 70 percent of all industrial electrical energy use goes to powering electric motors. These motors are the workhorses of business, from pumps moving fluids to fans moving air to compressors, conveyors, and every type of machine that depends on rotational force to …
5.5 Things Power Plant Engineers Need to Know About Pumps
Reduction in throttling loss is the major reason for VSD systems’ higher efficiency. A small portion of energy savings also comes from the efficiency improvement of the electric motor. Overall, energy savings of up to 70% (depending on the duty cycle) can be achieved with VSD pumps as compared with conventional pumps.

Energy savings With Variable Speed Drives According to Plastics Technology, the hydraulic pump-motor(s) account for 80% of the total energy usage on an injection molding machine. Even during periods of low hydraulic demand a maximum fixed-volume flow is produced. An example of the wasted energy at low demands is during the cooling stage of the …
If each piece of equipment is over-engineered, the power plant will have a system that is too large, performs at less than optimum efficiency, consumes excessive energy and adds higher maintenance …
Cost-optimized pump operation Pumps are by far heaviest consumers of electricity. With the cloud-based application SIWA Optim you can optimize your pump schedules based on current plant data, demand forecast, and daily updated prices. This enables a reduction of energy consumption and costs by up to 15 % whilst safeguarding the supply at the …

Efficient plant operation Today, power producers operate in a highly competitive marketplace.
VARIABLE SPEED DRIVEN PUMPS-BEST PRACTICE GUIDE. 3 PREFACE AND ACKNOWLEDGEMENTS This guide is the result of co-operation between three different industries whose goal was to produce a document that would clearly define; in simple terms the information required when planning to use an electronic Variable Speed Driven Pumping System. The guide
Energy Tips STEA Steam Tip Sheet 21 Consider Steam Turbine Drives for Rotating Equipment Steam turbines are well suited as prime movers for driving boiler feedwater pumps, forced or induced-draft fans, blowers, air compressors, and other rotating equipment. This service generally calls for a backpressure noncondensing steam turbine. The
