When it comes to handling low-flow liquids in industrial applications, precision matters. Whether it’s chemical injection, flavoring additives, or dosing enzymes into a process line, the ability to control small volumes of fluid with consistency and reliability is critical to product quality, efficiency, and compliance.
Illinois Process Equipment (IPE) offers pumping solutions specifically designed to meet the challenges of low-flow liquid handling across industries such as chemical processing, food and beverage, and water treatment.
The Challenge of Low-Flow Pumping
Low-flow pumping typically refers to flow rates under one gallon per minute (GPM), though this threshold can vary depending on the application. These scenarios often involve viscous, shear-sensitive, or hazardous fluids that require careful material selection and precise control.
Common challenges include:
- Maintaining consistent flow at low velocities
- Avoiding cavitation and pulsing
- Ensuring compatibility with corrosive or temperature-sensitive fluids
- Preventing product waste due to over- or under-dosing
Pump Technologies for Low-Flow Applications
There’s no one-size-fits-all solution for low-flow pumping. At IPE, we help customers select from a range of pump technologies based on the fluid characteristics, required accuracy, and system layout.
Diaphragm Metering Pumps
Ideal for dosing chemicals in precise volumes, diaphragm pumps offer pulse-free flow and excellent chemical resistance. Options like Grundfos SMART Digital Dosing Pumps include integrated control systems and adaptive flow algorithms to maintain accuracy across changing conditions.
Peristaltic Pumps
These self-priming, low-shear pumps are perfect for delicate fluids or applications that cannot tolerate cross-contamination. Because the fluid never touches internal components, peristaltic pumps offer exceptional cleanability, especially important in food and pharma environments.
Gear Pumps
Gear pumps offer tight volumetric control, consistent output for viscous fluids, and continuous dosing. When paired with VFDs (variable frequency drives), gear pumps can deliver highly accurate flow control for blending, sampling, or continuous feed.
Integration with Processing Systems
Low-flow applications often don’t operate in isolation. They’re part of a larger system involving mixers, tanks, heat exchangers, and control valves. IPE supports system-wide integration with pump services, including:
- Custom skid fabrication
- Turnkey pump and control panel assembly
- Installation and startup support
- Remote condition monitoring solutions
We assist clients in designing process systems that enable pumps and processing equipment to operate effectively within the larger production environment.
Service and Support that Extends Equipment Life
Because accuracy is so critical in low-flow systems, even small mechanical issues can lead to major problems. IPE offers a full range of field and shop pump services to keep equipment running as designed. Our service teams help extend equipment life and minimize waste by catching wear issues before they impact flow consistency.
