Common usage problems of stainless steel self-priming pumps


A stainless steel self-priming pump is not primed with water. This is a common problem. Many people assume that since it's self-priming, it should automatically draw water without priming. This is a mistake. Self-priming pumps pump liquids and cannot create a vacuum. Therefore, priming is essential when the pump is first used without any liquid stored in the pump body. Conversely, if the pump is turned on without priming during initial use, it will not pump liquid. Long-term operation can also cause the pump to dry-run due to idling, burning components such as the seal and impeller.
