American-Marsh Pumps

The page includes end-suction, split-case, vertical turbine, and submersible equipment, along with engineered systems for different water-handling duties.

It is worth evaluating for suitable water applications where capacity and access to internal components matter. Compare the design with the actual operating curve and installation constraints.

Suitable installations include wells, water supply, and irrigation. Water level, setting depth, intake conditions, and available driver arrangements guide selection.

Suitable models can serve circulation and process-water duties. Provide fluid mixture, temperature, flow, and system head so the right configuration can be reviewed.

Provide the nameplate, existing performance data, piping dimensions, and installation drawings. Include any changes in demand since the original unit was installed.

Its rating, speed, mounting, condition, and starting requirements must be checked. The motor must suit the full expected operating range, not just one nominal duty point.

Start with required flow and total head, then check the operating point against the pump curve. Horsepower or pipe size alone is not enough to select a pump.

Possible causes include suction restrictions, air entry, worn hydraulic components, incorrect rotation, or changed system resistance. Compare measured flow and pressures with the expected operating point.

Cavitation occurs when local pressure falls low enough for vapor bubbles to form and then collapse. Review suction conditions, liquid temperature, and available inlet head when noise or performance changes appear.

Alignment, bearings, impeller condition, mounting, piping strain, and hydraulic conditions can all contribute. Record when vibration occurs so inspection can address the cause rather than just the symptom.

Dry running, unsuitable seal materials, poor flush conditions, shaft movement, or normal wear can cause leakage. Repeated failures warrant a review of the operating conditions and seal arrangement.

Use the model's instructions and service history to set intervals. Track operating hours, leakage, vibration, lubrication requirements, and performance changes rather than relying on a universal calendar schedule.

Compare inspection findings, parts availability, repair cost, downtime, and current duty requirements. Rebuilding is worth evaluating when the casing and major components remain suitable for the application.

It may help when demand varies and the system allows speed adjustment. Check minimum flow, motor suitability, control needs, and measured energy use before estimating savings.

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.
