1 Pump Maintenance - Repair Brian Trombly Mo Droppers Cummins Bridgeway, Gaylord, Mi The basic centrifugal pump consists of two main elements: 1. The rotati ng element – whi ch include s a n impeller and a shaft. 2. The stationar y element – which inc ludes a casing, stuffing box (or seal cavity) and bearings. Pump Reliability Factors ~ Sizing factors: • A 100 HP electric motor on a 50hp load will work and run smooth and cool and only use 50 HP of energy. (Still not recommended). • A 100 GPM pump on a 50 GPM demand is a bad bet. Pump will run rough, hot and waste energy. Pumps need to be sized based on pressure, flow-rate and head. T he wrong pump for the job will cost you $$$ in energy and maintenance cost.
