BASSFLY DC Gear Pump 5V 6V 9V 12V, Self-Priming, Bidirectional

Description

• Bidirectional self-priming design with a Japanese NIDEC SANKYO gear pump structure; supports forward and reverse self-priming for flexible liquid-flow direction and transport of liquids including oil and water.
• Multi-voltage compatibility: supports DC 5V, 6V, 9V, and 12V; maintains stable operation even with 18V overvoltage and is compatible with various devices and systems.
• High-quality Japanese components: an internal water seal and an ABS and PPE outer housing provide durability and sealing for long-term use.
• Precise control of low flow rates: the gear-pump design provides moderate flow rates for applications requiring stable, controllable liquid transfer, such as analytical instruments and perfusion systems.
• Lightweight and portable: each pump weighs approximately 103g, allowing flexible installation in embedded or portable devices and supporting various cable and interface configurations.

The pump has not been used, but it has a small surface scratch caused by transportation. The parameters of the four pumps are nearly identical; the difference is in the cable and plug. This is a Japanese NIDEC SANKYO gear pump and a self-priming bidirectional pump. Nidec products are generally characterized by good quality and attention to detail. They use Japanese Mabuchi motors and a Japanese NOK water seal. The materials consist primarily of ABS and PPE, and each subcomponent has a component identification mark. The pump's rated voltage is 12V, but 5V is sufficient for operation. Even with 18V overvoltage, the operating condition remains very good. The higher the voltage, the higher the liquid pressure. With a reduced nozzle and no tube, no pressure is noticeable. The characteristic of a gear pump is that its flow rate is generally not high. If you need to change the direction of water flow, reverse the positive and negative wiring terminals. Test the parameters under several typical voltage conditions for reference: 5V: pump water current, 40mA. 12V: pump water current, 80mA. A single pump weighs approximately 103g.
