Frequently Asked Questions
Q: What liquids are compatible with this 12V diaphragm pump?
A: This micro electric diaphragm pump is compatible with clean water and alcohol-based liquids. It is not designed for use with abrasive slurries, oils, or corrosive chemicals beyond those listed.
Q: How does the automatic start/stop function work on this boosting pump?
A: The pump features a pressure-activated automatic start/stop mechanism. It activates when it detects a drop in line pressure (demand for flow) and shuts off automatically once the desired pressure is restored — providing efficient, hands-free operation without manual switching.
Q: Is this diaphragm pump suitable for high-temperature applications?
A: Yes. This pump is specifically engineered to handle elevated liquid temperatures, making it well-suited for steam ironing machines, hot water circulation, and other high-temperature home appliance or commercial uses. Always verify your specific temperature range against your system's requirements before installation.
Q: What does the pre-shipment water test mean for my new pump?
A: Every unit is individually tested with water before it ships to confirm full functionality. You may notice small traces of moisture or water marks inside the packaging — this is a normal result of quality testing, and your pump is guaranteed to be brand new.
