The WFB No-seal Automatic-control And Self-priming Pump is a high-performance fluid transfer solution designed by SPMC, integrating advanced power sealing device to eliminate leakage risks and extend service life. Unlike traditional pumps relying on packing or mechanical seals, this pump features permanent self-priming capability—no manual priming is needed after the first use, significantly reducing operational hassle. It excels in temperature tolerance and pressure resistance, making it ideal for harsh industrial environments. Widely applied in chemical industry, medicine production, food processing, electroplating, and civil construction, it efficiently transfers corrosive, viscous, or clean liquids while maintaining stable performance.

Equipped with a power sealing device, the pump avoids seal wear and leakage. Common issues with traditional pumps. Its seal service life is 10x longer than mechanical seals, cutting maintenance costs.
The built-in electric air control valve ensures reliable self-priming, even after long idle periods. The automatic-control system adapts to flow/head changes, reducing manual monitoring.
With wear resistance (via stainless steel 304/316 or reinforced polypropylene materials) and low vibration, it operates quietly in sensitive areas like food factories. Its compact structure enables easy movement and installation.
All pumps comply with GB 9115.2-2000/GB 9115.3-2000 flange standards—metal models have 1.0MPa flange pressure, non-metallic ones 0.6MPa. Each unit undergoes 48-hour pressure testing before delivery. SPMC provides a 2-year warranty for the power sealing device and offers customizations for special media (e.g., high-viscosity liquids).
No. Its permanent self-priming design retains fluid in the chamber after the first use, enabling instant startup next time.
Yes. Choose the wear-resistant steel (JM6) material option to handle liquids with small particles.
