What is the roller pump capacity, speed, max pressure, and spray material specification?

The choice indicating a roller pump capacity of 0-35 gpm, speed of 600-2600 rpm, a maximum pressure of 300 psi, and a specification for nonabrasive materials is correct because it aligns with the general operational parameters expected of roller pumps used in aquatic pest management. Roller pumps are designed to handle liquid applications effectively, and their capacity range typically accommodates moderate flow requirements found in various aquatic treatment scenarios. The specified speed range ensures adequate pump performance while maintaining efficiency.

A maximum pressure rating of 300 psi is suitable for most nonabrasive applications, allowing for effective distribution of spray materials without risk of damaging the pump or the materials themselves. The specification for nonabrasive materials is essential, as it ensures the integrity and longevity of the pump when used with standard pesticide formulations and other treatment solutions, which are typically non-abrasive in nature.

The other options vary in their specifications either by exceeding functional typicals or including abrasive materials which might be inappropriate for standard use with roller pumps. Such misalignments could lead to performance issues or equipment damage, underscoring why the selected answer is the most appropriate choice for understanding roller pump characteristics in aquatic pest management.
