1pc KPV14A3A DC 3V Diaphragm Vacuum Pump Compact Negative Pressure Air Pump Description A compact diaphragm vacuum pump designed to generate stable suction and negative pressure for small air and gas applications. The KPV14A3A runs from 3V DC power and is suitable for integration into portable or lowvoltage systems that require a reliable source of vacuum. Key benefits Lowvoltage operation: Designed for 3V DC supply, making it easy to power from battery packs, USB stepdown modules, or lowvoltage controllers. Effective suction: Diaphragm mechanism creates negative pressure for air and gas handling in tight spaces where larger pumps are impractical. Easy integration: Small, singleunit pump that can be installed into custom enclosures or experimental setups with minimal modification. Versatile use: Supports a range of smallscale applications where controlled suction or vacuum is required. Important attributes Model: KPV14A3A Power: DC 3V Function: Diaphragm vacuum pump for gas and air; produces suction and negative pressure Package: 1 piece Performance and compatibility Works with standard 3V DC power sources, including batteries and compatible lowvoltage power supplies. Suitable for use alongside microcontrollers and automation controllers for simple on off control. Compact form factor fits into small equipment, instruments, and portable devices. Practical applications Laboratory and testing setups: Create localized negative pressure for smallscale experiments, air sampling, or sensor calibration. Electronics and robotics: Supply suction for vacuum grippers, part handling, and small pneumatic actuators in hobby and light industrial assemblies. Maintenance and inspection: Assist with leak detection, fluid transfer in confined spaces, or removal of air from small sealed components. What it solves Provides a compact, lowvoltage solution when space or power availability prevents use of larger vacuum systems. Simplifies design for portable devices that need suction or negative pressure without complex plumbing or voltage supplies. Enables quick replacement or prototyping with a single, readytoinstall pump. Technical note This listing is for one KPV14A3A DC 3V diaphragm vacuum pump. Verify compatibility with your existing power source and control circuitry before installation.
