KEY TAKEAWAY
Pump flow, pressure, chemical compatibility and control requirements must be specified together.
Define the chemical and process requirement
Start with the chemical name, concentration and safety data, then describe the purpose of dosing. The required treatment dose should come from an appropriate process assessment; it should not be inferred from the pump size or a generic online example.
Share the water flow range, operating hours and injection conditions with the designer. A variable-flow process may need proportional control rather than a pump that runs continuously at one setting.
Check wetted materials and pressure
The pump head, seals, valves, tubing and injection components need to be compatible with the chemical and operating temperature. Request written compatibility confirmation for the proposed materials and chemical concentration.
Select against the required delivery rate at the actual backpressure. Review the manufacturer's performance data and permitted operating range. A maximum flow figure and a maximum pressure figure should not be assumed achievable together.
Specify the complete dosing assembly
Ask the installer to assess the suction arrangement, injection point, calibration method and required safety accessories. Storage, containment and operator protection should follow the chemical instructions and relevant site requirements.
- Chemical name, concentration and safety data
- Required dosing range and process flow
- Injection pressure and suction conditions
- Power supply, signal type and control method
- Tank, tubing, valves and compatible service parts
Plan commissioning and ongoing checks
Define how the delivered flow and process result will be verified during commissioning. Keep a record of settings, calibration, inspections and consumable replacement. Provide operator training for the exact equipment and chemical in use.
For export enquiries to African markets, send Aqua Best the process brief and destination. The pump, tank and accessories can then be quoted as a defined package with the local installation scope made clear.
