The core competitiveness of the Keyukang KYK2748VPM micro vacuum pump is reflected in three key aspects: outstanding precision pressure regulation (combining automatic pressure control with a 0–65 kPa negative pressure range to meet diverse application needs), strong adaptability and practicality (compact, easy to integrate, oil-free and low-noise, suitable for multiple industries), and expanded application scenarios through material upgrades (ABS777E material offering a balanced combination of performance for complex environments). The product was granted corresponding patents in July 2025.
The Keyukang micro vacuum pump integrates automatic pressure regulation with a 0–65 kPa negative pressure range, enabling precise matching of pressure control requirements across different applications. Whether for sample extraction experiments requiring stable low-pressure environments (e.g., 20–30 kPa negative pressure) or for small devices that demand higher vacuum levels for pressure holding (e.g., 50–65 kPa negative pressure), the pump ensures the negative pressure remains stable within the preset range, preventing performance deviations or experimental inaccuracies caused by pressure fluctuations.
While delivering precise pressure control, the Keyukang micro vacuum pump retains a compact and lightweight design, allowing easy integration into small instruments or portable devices. In addition, the oil-free lubrication design eliminates the risk of oil contamination to samples or the environment, while offering low noise and low failure rates. This makes the pump suitable for a wide range of fields, including home appliances, scientific research, medical equipment (such as small negative-pressure suction devices), environmental monitoring, and electronic component packaging. It demonstrates particular value in applications with stringent requirements for vacuum precision and device size.
Based on the original product design, the material has been upgraded to ABS777E. Its moderate butadiene content enhances impact strength; the styrene component provides excellent molding stability; and the acrylonitrile component improves chemical corrosion resistance. This material achieves a good balance between toughness and heat resistance, while offering excellent dimensional stability, low shrinkage and minimal deformation after processing. It also delivers a fine and uniform surface finish, facilitating subsequent painting and printing processes.
