Figure 5. Molded-to-size stator core Starting Torque Starting torque should be considered. This is important in determining the HP required for the pump, but also impacts the life of the stator and its efficiency. Optimizing starting torque versus efficiency is important in the final selection. Selecting a pump manufacturer that optimizes stator compression (see Figure 6) for performance and balances efficiency is essential to optimal PC pump performance. Figure 6. Optimized stator compression Conclusion In summary, make careful choices when considering what type of PC pump to purchase, and what stator options to choose. It impacts the initial capital cost and affects the overall life cycle cost of the pump. Choosing the lowest cost pump may not always be the best choice. Consider the stator material, number of stages and type of geometry, construction and the quality of manufacturing to ensure the best overall value. This value is maximized when considering capital cost, operating cost, spare parts cost and maintenance cost. Avoid considering only one of these during the evaluation.
