The KYK2748EPM Micro Diaphragm Pump is engineered for personal healthcare and smart home appliances that demand stringent safety and comfort standards. At its core is a high-stability 320 motor (typically rated at 24V, 3000 r/min), which provides a durable and reliable power foundation for a wide range of applications. The pump excels at delivering highly controllable and smooth negative pressure (vacuum) output, a critical feature for devices with direct human contact. Whether for breast pumps simulating gentle, natural suction rhythms or for beauty instruments requiring a safe and effective user experience, the KYK2748EPM delivers precisely calibrated power to maximize both functionality and user comfort. With its compact design and optimized noise control, it integrates seamlessly into various portable and desktop devices, including vacuum food savers for extending food freshness and vacuum packaging systems for enhancing product quality.
