Technical FAQ: DC Micro Diaphragm Pumps
Micro Diaphragm Pump Technical FAQ
1. What is the maximum self-priming height of this DC micro diaphragm pump? The maximum self-priming height is up to 2 meters (6.5 feet). This is achieved through a high-efficiency valve design and airtight diaphragm seals, making it ideal for coffee machines and medical devices where the water reservoir is located below the pump level.
2. How can I adjust the flow rate of a 12V/24V micro water pump? You can precisely control the flow rate by adjusting the input voltage or using PWM (Pulse Width Modulation) speed regulation. Reducing the voltage lowers the motor speed, allowing for fine-tuned dosing in precision medical or laboratory applications.
3. Can the Pincheng micro diaphragm pump run dry without damage? Yes, our diaphragm pumps can run dry for extended periods. Unlike centrifugal pumps, the diaphragm design does not rely on the pumped medium for cooling or lubrication of the critical seals, ensuring high reliability in intermittent air and liquid transfer.
4. What is the noise level of this micro pump during operation? The noise level is strictly controlled below 45dB at a 30cm distance. By utilizing internal acoustic damping and a balanced eccentric motor design, our pumps are suitable for “whisper-quiet” environments like hospital wards and high-end offices.
5. Are the pump materials safe for food-grade or corrosive gas sampling? Yes, we offer multiple material options including FDA-compliant EPDM for food/beverage use and PTFE (Teflon) for corrosive gas sampling. All fluid-contact components are certified to meet RoHS and REACH environmental standards for global compliance.
