Pump Solutions for Transfer, Circulation and Dosing Duties
Pumps selected around duty point, fluid properties, materials, installation conditions and the required operating cycle.
[ The Range ]
Five Pump Categories
Centrifugal Pumps
Continuous transfer and circulation of water, utilities and suitable process liquids.
Positive Displacement Pumps
Controlled transfer of viscous fluids or duties requiring predictable displacement.
Air-Operated Double-Diaphragm Pumps
Intermittent transfer, drainage and selected chemical, slurry or solids-containing duties.
Submersible and Drainage Pumps
Sumps, dewatering, wastewater and drainage applications.
Metering and Dosing Pumps
Controlled injection or low-flow chemical dosing duties.
[ 01 / Overview ]
Depending on the service and the selected manufacturer’s range, suitable pump technologies may include centrifugal, positive displacement, air-operated double-diaphragm, submersible and drainage, and metering and dosing pumps.
Each category below states the duties it typically suits and the factors that govern selection. The final choice depends on the installed system, not on flow rate alone.
Pump Categories
| Pump category | Typical application | Selection focus |
|---|---|---|
| Centrifugal Pumps | Continuous transfer and circulation of water, utilities and suitable process liquids. | Duty point, system curve, suction conditions, efficiency, materials, seal and driver. |
| Positive Displacement Pumps | Controlled transfer of viscous fluids or duties requiring predictable displacement. | Viscosity, speed, pressure, relief protection, clearances and fluid compatibility. |
| Air-Operated Double-Diaphragm Pumps | Intermittent transfer, drainage and selected chemical, slurry or solids-containing duties. | Air supply, fluid compatibility, solids size, suction lift, diaphragm and wetted materials. |
| Submersible and Drainage Pumps | Sumps, dewatering, wastewater and drainage applications. | Liquid level, solids passage, cable length, installation depth, materials and operating cycle. |
| Metering and Dosing Pumps | Controlled injection or low-flow chemical dosing duties. | Required accuracy, flow range, discharge pressure, turndown and chemical compatibility. |
Typical Applications
- Cooling-water and chilled-water circulation
- Water supply, transfer and treatment systems
- Wastewater, drainage, sump and dewatering duties
- Marine seawater, ballast and auxiliary services
- Chemical transfer and dosing
- Process liquid, utility and equipment-support systems
- Fuel, lubricant or viscous-fluid transfer where the selected pump is suitable
