Webtrol Pumps

The general-purpose page includes centrifugal, booster, vertical multistage, and submersible well-pump options for water-handling applications.

Multiple stages can provide the pressure needed for suitable boosting or process-water duties. Check the inlet supply, temperature, and minimum operating flow.

Suitable models may serve irrigation water transfer or boosting. Provide water-source conditions, required flow, discharge pressure, and the expected seasonal operating pattern.

Include the lowest available inlet pressure, required outlet pressure, peak demand, and number of simultaneous users. Also describe existing tanks and controls.

Only within its stated capability. Describe contaminants and consider suitable protection rather than assuming every water pump tolerates abrasive particles.

The curve shows performance across a range of flows. Matching the required operating point helps avoid selecting a pump simply because its connections and horsepower match.

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.
