To maximize performance and extend the lifespan of the DKYB Pump with Flow Meter, follow these operational best practices:
Fluid Compatibility
Verify that the fluid being pumped is compatible with pump seals, impellers, and flow meter sensors.
Avoid corrosive fluids that exceed material compatibility ratings.
Pressure and Flow Limits
Operate the pump within the specified flow rate and pressure range to prevent mechanical stress and sensor errors.
Sudden pressure spikes or cavitation can damage both the pump and flow meter.
Temperature Control
Ensure the operating fluid temperature is within the recommended range.
High-temperature liquids may require additional cooling or insulation.
Regular Monitoring
Check flow readings frequently to detect anomalies.
Integrate with PLC or SCADA systems for automated monitoring in industrial setups.
Routine Maintenance
Inspect seals, bearings, and coupling alignment regularly.
Clean flow meter sensors periodically to maintain accurate measurements.
The DKYB Pump with Flow Meter undergoes rigorous quality control procedures to ensure reliability, safety, and compliance with industry standards:
| QC Stage | Description | Purpose |
|---|---|---|
| Material Inspection | Raw materials are checked for chemical composition and mechanical properties | Ensures durability and corrosion resistance |
| Component Testing | Pump impellers, flow sensors, and seals tested individually | Verifies compliance with design specifications |
| Assembly Verification | Fully assembled pump and flow meter tested for alignment, rotation, and calibration | Ensures mechanical and measurement accuracy |
| Factory Calibration | Flow meter calibrated under controlled flow conditions | Guarantees precise flow measurement |
| Performance Testing | Pump and meter tested under operational pressures and temperatures | Confirms efficiency and reliability |
| Packaging & Inspection | Final inspection and protective packaging | Prevents damage during transportation |
Tip: Only use DKYB-certified parts and accessories to maintain warranty compliance and operational reliability.
Verify all components are included, including pump, flow meter, coupling, mounting brackets, and electrical cables.
Ensure the installation site is stable, vibration-free, and accessible for maintenance.
Check that the fluid piping is compatible with pump and flow meter specifications.
Confirm power supply specifications match the motor and control unit.
Mounting the Pump
Place the pump on a stable surface using supplied brackets.
Ensure proper alignment with the pipeline and secure all bolts tightly.
Connecting the Flow Meter
Install the flow meter in line with the fluid direction as indicated on the sensor.
Use appropriate threaded or flanged connections to prevent leaks.
Electrical Connections
Connect power cables to the motor drive and control panel according to the manufacturer’s wiring diagram.
Ensure proper grounding and compliance with local electrical codes.
Initial System Check
Open inlet and outlet valves gradually.
Energize the pump and observe the flow meter readout.
Verify that the pump is operating within pressure, flow, and temperature limits.
Calibration Verification
Perform initial calibration checks on the flow meter to ensure accurate flow measurement.
Adjust settings if necessary according to the operation manual.
