At what percentage should a chemical feed pump be operated for optimal performance?

Operating a chemical feed pump at a percentage range of 30-70% is considered optimal because this range allows the pump to achieve a good balance between flow rate and the efficiency of the chemical injection process. When a pump operates within this range, it typically experiences less wear and tear compared to running it at very low or very high percentages.

In the lower percentage ranges, such as 10-20%, the pump may not be able to maintain stable operation, which can lead to issues such as pulsation or inadequate chemical dosing. Operating at higher percentages, particularly in the upper ranges like 70-90%, may also increase wear on pump components and lead to potential thermal issues or cavitation, which can damage the pump over time.

Therefore, maintaining the pump operation within the 30-70% range ensures that it runs efficiently and reliably, leading to better performance in managing the chemical feed process while also extending the lifespan of the pump itself.
