Rotech Pumps

The page presents process-pump, magnetic-drive, split-case, and replacement-part options. Confirm the current model and configuration against the required application.

They address different equipment and service requirements. Identify the project specification and applicable edition, then verify the offered pump's documented compliance rather than assuming the terms are interchangeable.

Potential replacements require comparison of the duty, materials, dimensions, driver, and connections. Confirm any claimed parts or dimensional interchangeability for the exact models involved.

It may suit water movement where capacity and service access are priorities. Compare the pump curve, installation footprint, and maintenance access with other designs.

It transmits torque without a conventional dynamic shaft seal through the containment boundary. Static joints and other components still need inspection and compatible materials.

Supply the model, serial number, part identification, and service conditions. Photos or drawings can help confirm the correct material and revision.

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.
