Proven Solutions: Save Energy, Save Money Improving closed pump impellers inner flow passage roughness to increase up to 11% peak efficiency and lower energy consumption. A coal-powered plant equipped with six boiler feed pumps can reduce parasitic loss, representing at least 500,000 annual savings (driving the pumps) by 1% of the power generated. This process and savings can also be applied to natural gas centrifugal closed pump impellers. Precision Surface Management Matters Kennametal Extrude Hone Abrasive Flow Machining (AFM) surface and flow enhancement solutions provide the energy segment with significant savings in pump efficiency improvements. The AFM process is the method of choice for material removal at the area of greatest restriction and surface improvement of passages not accessible by other methods. AFM has documented efficiency proven solutions in the automotive and aerospace industries. Two-way flow AFM process is a natural fit for closed impellers and diffusers. Inner flow passages of the impellers and diffusers benefit from AFM’s selective material removal as well as surface finish improvement both contributing to improved pump efficiency.
