Finish Thompson Pumps

The page includes magnetic-drive centrifugal, drum and barrel, sealed centrifugal, and air-operated diaphragm options for fluid-transfer applications.

Consider one for transferring liquid from a compatible container. Specify container depth, fluid properties, required delivery, and the intended motor or drive arrangement.

No. The tube, seals, hose, and dispensing components must all suit the chemical and cleaning procedure. Separate equipment may be appropriate where cross-contamination is a concern.

A magnetic-drive design transfers torque across a containment barrier, while a conventional sealed design uses a shaft sealing arrangement. Compare process suitability and service needs for both.

Suitability depends on the pump type and fluid behavior. Provide viscosity at operating temperature so flow, inlet requirements, and drive load can be evaluated.

Check container access, hose routing, discharge control, material compatibility, and application-specific electrical requirements. The complete transfer assembly matters, not just the pump tube.

Identify every chemical, concentration, temperature, and cleaning fluid. Compatibility must cover the casing, seals, gaskets, bearings, and other wetted components, including any changes during the process.

Do not assume it can. Many designs depend on liquid for lubrication or cooling; follow the exact pump's operating limits and specify dry-run protection where appropriate.

Possible causes include gas in the suction line, restrictions, worn components, changed viscosity, or insufficient inlet pressure. Compare operating measurements with the selected pump's performance curve.

Follow the facility's isolation and spill-response procedures and have qualified personnel inspect the system. Provide the chemical details and operating conditions before arranging repair or replacement parts.

No. Removing a dynamic shaft seal addresses one leakage path, but piping joints, static seals, and containment components still need correct installation, compatible materials, and inspection.

Temperature changes viscosity, vapor pressure, and material limits. Review normal operation, startup, cleaning, and upset conditions so the pump remains suitable throughout the intended duty.

Follow the model's schedule and adjust inspection frequency for the fluid and operating history. Document containment condition, performance trends, and any protective-device alarms.

Often, but inspection must establish whether wetted parts and containment components remain serviceable. Provide decontamination information and compare repair scope with the cost and suitability of replacement.

Contact Process & Power at (901) 362-5500 with your location, equipment identification, and application or service concern. The team can review selection, parts, and service options for your needs.

Include the required duty, fluid or process details, operating conditions, utilities, and installation dimensions. For existing equipment, add nameplate photos, model and serial numbers, and a description of the problem or planned change.
