Water Flow Measurement:
Water flow is measured using a high-precision miniature electromagnetic flowmeter (electromagnetic induction volumetric flowmeter).
The test setup includes approximately 1 m inlet and outlet tubing to simulate practical installation conditions.
Noise Measurement:
Noise is measured at a distance of 1 m from the pump during normal operation under standard working conditions.
Lifetime Testing:
Lifetime is evaluated under continuous 24-hour no-load operation, with both inlet and outlet open to atmosphere (ambient pressure conditions).
For most OEM applications, the standard material configuration provides a practical balance of compatibility, durability, and stable performance.
| Component | Material / Feature |
|---|---|
| Pump Head | PA66 engineering plastic |
| Diaphragm | EPDM |
| Valve | EPDM |

Unstable flow often results from backpressure fluctuations, improper tubing connections, or particle contamination in the fluid path. Installing precision filters, using rigid tubing, and ensuring tight fittings can stabilize flow and prevent suction or discharge inconsistencies.
Pump performance can be affected by vibration, orientation, and intermittent operation. Using vibration-damping mounts, proper inlet/outlet alignment, and avoiding long periods of dry running helps maintain consistent gas-liquid transfer and extends pump lifetime.
Select compatible materials for corrosive fluids, control inlet/outlet pressure, and provide speed control signals if needed. Ensuring system cleanliness and integrating the pump with appropriate filtration and feedback loops reduces maintenance and improves operational stability.
