Verify all wetted components against actual service conditions.
Hydraulics
Calculate complete suction and discharge requirements.
Protection
Contain leaks and detect abnormalities.
- Chemical source (tank, tote, drum connections)
- Suction conditioning (strainers, flooded suction provisions)
- Transfer or metering pump selection
- Pressure management (relief, controls)
- Isolation and service access
- Injection and process interface
Transfer pumps move bulk chemical between locations; metering pumps deliver controlled doses tied to process demand — often requiring separate pump stages rather than forcing one pump to perform both duties.
Secondary containment requires engineering around route, pressure, drainage, access, and leak-location methodology. Detection sensors must be positioned where fluid actually flows during a credible leak scenario.
- Define all chemicals and operating states
- Separate transfer from metering duty
- Calculate the hydraulic envelope
- Verify the complete wetted path
- Select pressure-control devices
- Engineer containment and leak response
- Define controls and safe states
- Complete manufacturer and regulatory review
What is a chemical feed system?
A complete apparatus including source connection, suction piping, pump, isolation valves, calibration devices, pressure accessories, injection hardware, secondary containment, instrumentation, and control logic.
What is the difference between transfer and metering pumps?
Transfer pumps move chemical at higher flow rates between locations; metering pumps deliver controlled volumes into processes. Complex systems may require both stages.
Can magnetic drive pumps run dry?
Most depend on pumped liquid for cooling and lubrication. Dry running risks overheating internal components, necessitating minimum-flow protection.
Do peristaltic pumps use check valves?
The pumping mechanism doesn't require them, though surrounding systems may need isolation, relief, anti-siphon, or backflow prevention.
When should systems use double containment?
Consequence-based analysis considering chemical hazard, route accessibility, occupancy sensitivity, and regulatory requirements determines necessity.
How do leak detection systems work?
Sensors in sumps, pans, or interstitial spaces trigger local alarms, PLC reporting, or shutdown sequences when material is detected.
Why use true-union valves?
They permit body removal without cutting surrounding pipe, reducing maintenance disruption while maintaining full material and pressure specifications.
What information specifies a chemical feed skid?
Chemical name, concentration, temperature, transfer/dosing rates, suction conditions, discharge pressure, specific gravity, viscosity, solids, vapor behavior, duty cycle, utilities, controls, area classification, and containment requirements.
