The electric power industry faces a situation in which significant investments are needed, and rate increases will be necessary to finance them. This will directly impact your company’s bottom line.
Pump systems are often heavy users of energy, especially large pumps that run continuously. Such pumps are often oversized and operating far from their best efficiency points and therefore waste considerable amounts of energy. Pumps are usually consuming more energy than necessary for one of the following reasons: the pump is oversized and has to be throttled to deliver the right amount of flow. Energy is lost in the valve; pumps that are not running close to their best efficiency points (BEP) operate at lower efficiency. Throttled pumps usually fall into this category; pumps running with by-pass, or recirculation, lines open; pumps are running although they could be turned off; the pump is worn and the efficiency has deteriorated; the pump/system was installed or designed incorrectly (piping, base plate, etc.)
Just as certain health symptoms in people are often – but not always – associated with certain illnesses, there are a few symptoms in pumping systems that often exist when there are improper sizing, selection, operation, or other issues that result in less-than-optimal performance.
Do you know how much your pumping systems are costing you?
In order to help facilities run their systems more efficiently and economically, a pump system assessment identifies problematic systems where the greatest opportunities for improvement exist.
This course will provide you an overview of Pumping System Optimization as well as case studies with potential cost savings.
- You will be able to recognize an inefficient pumping system.
- You will be able to discuss potential energy savings in a pumping system.
- You will be able to explain how to assess a pumping system.
- You will be able to identify steps to improve system efficiency.
