Pumps shall be listed and labeled in accordance with __ __.

Pumps must be listed and labeled in accordance with UL 343, which establishes the safety standards for electric pumps. This standard pertains to the construction, performance, and testing of power-driven pumps, ensuring they meet the necessary safety and operational criteria. Compliance with UL 343 ensures that the pumps are designed to minimize risks associated with mechanical and electrical failures, providing assurance to end-users about the reliability and safety of the equipment.

Other UL standards mentioned might cover different types of equipment or specific applications but do not specifically address the requirements for pumps. This makes UL 343 the relevant standard for ensuring the safety and efficacy of pump systems.
