Frequently Asked Questions: 310 Medical Micro Water Pump
What makes the 310 micro pump “medical-grade” compared to standard pumps?
The primary difference lies in material safety and reliability. Our medical-grade 310 pumps utilize FDA-compliant EPDM diaphragms and USP Class VI-compatible housings. Unlike consumer-grade pumps, these are manufactured in controlled environments to prevent contamination and undergo rigorous 500+ hour continuous duty cycle testing to ensure zero-failure performance in critical healthcare applications.
Can this micro pump handle high-viscosity medical gels or only thin liquids?
It is specifically engineered for both. While standard pumps often clog with thick fluids, our 310 series features a reinforced valve structure and a high-torque DC motor. This allows it to maintain a consistent flow rate for high-viscosity hand sanitizers and ultrasound gels without overheating or motor stall, ensuring a smooth, drip-free user experience.
How does this pump manage noise levels for hospital or bedside use?
Patient comfort is a priority. We’ve optimized the internal motor balance and used vibration-dampening elastomers to keep noise levels below 40.5 dB. In a typical medical environment, this is whisper-quiet. For integration, we recommend using flexible silicone tubing to further isolate mechanical resonance from your device’s housing.
Is the 310 micro pump compatible with alcohol-based disinfectants?
Yes. The pump head and internal seals are made from chemically resistant EPDM and PP polymers. These materials are specifically tested for long-term exposure to 75% Ethyl Alcohol and Isopropyl Alcohol (IPA). They won’t swell, crack, or degrade, which prevents internal leaks and maintains the chemical purity of your disinfectant.
What is the self-priming capability of this 6V micro liquid pump?
Our 310 diaphragm pump is fully self-priming up to 0.5 meters (1.6 feet). This means it can draw liquid from a reservoir located below the pump level without needing manual priming or a gravity feed. For medical designers, this provides greater flexibility when arranging internal components in compact, handheld, or wall-mounted devices.
