Iwaki Metering & Process Pumps

Iwaki pumps handle chemical transfer, circulation, and controlled chemical dosing. Applications include water treatment, chemical processing, metal finishing, electronics manufacturing, and other operations requiring materials compatible with the pumped liquid.

Iwaki offers magnetic-drive centrifugal pumps, chemical metering pumps, air-operated double-diaphragm pumps, and high-purity pumps. The appropriate product family depends on whether the application requires bulk transfer, circulation, or precise dosing.

A magnetic-drive pump transfers motor rotation to the impeller through magnetic coupling. This arrangement eliminates a conventional rotating shaft seal, reducing a common potential leakage point in chemical-transfer applications.

A transfer pump moves liquid between locations or circulates it through a process. A metering pump delivers a controlled quantity of chemical, making it suitable for dosing applications where feed rate matters.

Selected Iwaki pumps are designed for corrosive chemical service. Compatibility must be checked for the specific chemical, concentration, temperature, and all wetted components, including seals, diaphragms, valves, and bearings where applicable.

Yes. Iwaki pumps are used in water-treatment applications involving chemical feed and fluid transfer. Pump selection should account for the treatment chemical, required dosage, discharge pressure, and operating schedule.

Yes. Iwaki offers high-purity pump products for applications with demanding fluid-handling requirements. Confirm wetted materials, cleanliness requirements, connection types, and any required documentation before selecting a model.

Start with the required flow, discharge pressure or total dynamic head, liquid properties, and suction conditions. For metering applications, also identify the minimum and maximum feed rates and required adjustment range.

Control capabilities depend on the model. Specify whether the application needs manual adjustment, external start and stop, or proportional dosing, then confirm that the selected pump supports the required control signals.

Calibration checks actual chemical delivery under operating conditions. Backpressure, fluid properties, suction arrangements, and component wear can affect output, so a setting alone may not confirm the delivered feed rate.

Suitability varies by pump design. Provide viscosity, solids concentration, particle size, and abrasiveness when requesting a selection. A pump intended for clean, thin liquids may be unsuitable for a slurry or thick chemical.

Do not assume dry-running capability. Many centrifugal pumps depend on the pumped liquid for internal lubrication or cooling. Follow the selected model's instructions and evaluate protection against an empty supply tank.

Maintenance depends on the pump type and service conditions. Tasks may include checking connections, inspecting wetted components, cleaning valves or strainers, and verifying metering output according to the manufacturer's maintenance instructions.

Possible causes include an empty supply tank, suction restrictions, trapped gas, worn components, or changing system pressure. Compare actual operating conditions with the pump's specifications before adjusting settings or replacing parts.

A replacement may be possible after comparing hydraulic performance, chemical compatibility, connections, electrical requirements, and controls. Matching only motor horsepower or pipe size does not establish that two pumps are interchangeable.
