Q1｜What type of flow measurement is used for this diaphragm pump?
This pump’s flow performance is specified and verified using a float-type flow meter (rotameter) under standard test conditions.
Float flow meters are widely adopted in micro pump testing because they provide a direct, stable indication of volumetric flow under low-pressure gas conditions. Actual flow in an application may vary depending on system resistance, tubing length, fittings, and operating pressure.
Q2｜What is the internal thread size, and which tubing is recommended?
The pump is equipped with G1/8 internal threads on the inlet and outlet ports.
For system integration, it is recommended to use PC-G1/8 push-in fittings, which allow quick and reliable installation.
Compatible tubing options include:
Ø6 mm tubing for compact layouts and lower flow resistance requirements
Ø8 mm tubing when higher flow stability or reduced pressure loss is needed
Tubing selection should be matched to system flow demand and total line length.
Q3｜What design or usage practices help extend pump service life?
Several system-level measures can significantly improve long-term reliability:
Install an inlet air filter to prevent dust, particles, or fibers from entering the pump chamber
Control operating temperature and avoid prolonged exposure to high ambient heat
Avoid excessive back pressure or continuous operation at maximum load
Ensure adequate ventilation around the pump housing for heat dissipation
Proper system design often has a greater impact on pump lifespan than the pump itself.
Q4｜What certifications does this diaphragm pump comply with?
This model is manufactured in compliance with:
CE requirements
RoHS directives
These certifications support use in regulated markets and confirm conformity with electrical safety and environmental standards.
Q5｜Where is the pump manufactured and shipped from?
The pump is manufactured and shipped directly from Shenzhen, China, by the original factory.
For samples and small-batch orders, international delivery is typically arranged via DHL or FedEx, ensuring fast and traceable shipment.
Direct factory supply allows better cost control, flexible OEM support, and shorter lead times.
