Unveiling the Principles of Compatibility
The universal compatibility of electric pumps for vacuum storage bags depends on the sealing mechanism, not the brand. The key factor is the alignment between the pump body's extraction rate (typically 5–10 L/min) and the bag's air release valve:
Rotary Valves: Compatible with 90% of the electric pumps currently on the market.
Spring-Loaded Valves: Require a specific air pressure threshold (≥ 0.6 MPa) to activate.
Silicone Seal Ring Thickness: The ideal range is 0.8–1.2 mm.
A Guide to Interface Types
Mainstream interfaces fall into three categories, much like different models of mobile phone chargers:
Threaded Interfaces: Highly versatile, though attention must be paid to the thread pitch (M8 × 0.75 is a common standard).
Snap-Fit Interfaces: Allow for quick attachment and detachment, but variations exist between different brands.
Magnetic Interfaces: An emerging technology; compatibility standards are still under development.
Scenario-Specific Usage Guide
Special use cases require additional consideration:
Compressing Thick Quilts: It is recommended to select a high-flow pump with an extraction rate of ≥ 8 L/min.
Travel Storage: Prioritize compact, USB-powered pumps.
Long-Term Storage: Pumps equipped with an automatic air-replenishment function offer greater reliability.
