Description
What Are Chemical Feed Systems?
Chemical feed systems are integrated packages used to store, meter, dose and introduce chemicals into a process or treatment system at a controlled rate.
Depending on the application, a chemical feed system may incorporate:
- Chemical feed pumps
- Chemical storage or day tanks
- Metering pumps
- Suction and discharge piping
- Isolation valves
- Check valves
- Pressure relief systems
- Flow measurement
- Level measurement
- Chemical injection points
- Instrumentation
- Control panels
- PLC automation
- HMI interfaces
- Safety interlocks
The system can be supplied as a compact skid-mounted package or customized for larger industrial installations.

Chemical-Compatible Materials
Material selection is an important part of chemical feed system engineering.
Depending on the chemical and process conditions, systems can be configured using materials such as:
- PVC
- CPVC
- Stainless steel
- Alloy 20
- Other suitable chemical-resistant materials
The appropriate material depends on factors such as:
- Chemical composition
- Chemical concentration
- Operating temperature
- Operating pressure
- Chemical compatibility
- Required service life
- Process conditions
Wetted components, piping, valves, seals, tanks and pump components should be evaluated for compatibility with the chemical being handled.
Automated Chemical Feed Systems
Chemical feed systems can be integrated with PLC-based process automation and HMI controls for centralized monitoring and operation.
Automation options can include:
- Automatic dosing control
- Pump start/stop
- Flow monitoring
- Tank level monitoring
- Chemical consumption monitoring
- Pressure monitoring
- High/low-level alarms
- Pump protection
- Automatic sequencing
- Process interlocks
- Emergency shutdown
- Alarm indication
- Local HMI operation
- Remote monitoring or control where required
Automation can help maintain consistent chemical feed rates while reducing manual intervention.
Skid-Mounted Chemical Feed Packages
Aegis Projects can integrate pumps, tanks, piping, valves, instrumentation and controls onto a common structural skid.
A typical package may include:
Chemical Storage/Day Tank → Feed Pump → Piping & Valves → Instrumentation → Injection Point → Control System
The skid-mounted configuration provides a compact and organized system that can be factory assembled and tested before delivery.
