Wilo Pumps

The page covers water circulation, pressure boosting, drainage, and wastewater duties, with equipment used in building services and industrial systems.

Its inlet and outlet are arranged in line, which can simplify some piping layouts. Check mounting requirements, service clearance, and the required operating duty.

A booster raises supply pressure to meet downstream demand. Selection should use the available inlet pressure and expected flow variation, including peak usage.

Control capability depends on the pump and package. Specify the required pressure or temperature response, external signals, and alarm connections before choosing the configuration.

Do not assume so. Solids passage, materials, motor protection, and the hydraulic design must suit the liquid; circulation and wastewater models serve different duties.

Results depend on actual load, operating hours, and system control. Compare measured performance at the required duty rather than relying on an efficiency label alone.

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.
