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).
The standard configuration is designed to balance chemical compatibility, stable operation, and long service life in typical OEM applications.
| Component | Material / Feature |
| Pump Head | PA66 engineering plastic |
| Diaphragm | EPDM |
