DC 6V Mini Air Pump, Vacuum-Liquid Dual Mode, High-Pressure for 4mm Tubing(DC 5V-6V / China Mainland)

Compact DC micro water pump, model JQB2438437, designed for reliable small-volume fluid transfer and easy integration into DIY and equipment projects. Key benefits and reasons to choose this pump: - Low power consumption and modest current draw make it suitable for portable and low-power systems, as the pump runs at a rated current of 0.29 A at DC 6V. - Broad compatibility with common DC supplies and controllers, since the pump operates at a rated voltage of DC 6V and a suitable voltage range of DC 5V to 6V. - Simple plumbing integration with matching 4 mm outer diameter inlet and outlet ports, enabling a tight fit with standard small-diameter tubing. - Compact form factor allows installation in confined spaces and makes the pump easy to mount in enclosures and prototypes. - Stable performance for continuous or intermittent operation in low-flow applications, reducing the need for oversized pumps in small systems. Important specifications: - Pump model: JQB2438437. - Inlet and outlet outer diameter: 4 mm. - Rated voltage: DC 6V. - Rated current: 0.29 A. - Suitable operating voltage: DC 5V to 6V. Performance and compatibility notes: - The 4 mm outer diameter ports are suitable for common small tubing used in hobby and prototype applications, offering leak-resistant connections when properly fitted. - The pump is compatible with 5V and 6V power supplies, USB power banks that provide sufficient current, and low-voltage battery packs, provided correct polarity and safe wiring practices are followed. - For control from microcontrollers or external drivers, use an appropriate switch or transistor driver to avoid driving the pump directly from limited-output pins. Practical use scenarios: - Small aquarium circulation and desktop terrarium water movement where compact plumbing and low power are priorities. - Prototype cooling and component drip loops in electronics projects that require gentle liquid circulation at low voltages. - Small hydroponic setups, plant watering modules, or tabletop fountains where precise, low-volume flow control is needed. Installation tips: - Use tubing that matches the 4 mm outer diameter ports for a secure connection and consider hose clamps for permanent installations. - Verify the power supply provides stable DC 5V to 6V and at least 0.3 A to ensure reliable startup and continuous operation. - Observe correct polarity during wiring and allow for adequate mounting space and ventilation for long-term use. This pump provides a compact, low-voltage solution for small fluid handling tasks with clear electrical and plumbing specifications for straightforward integration.
