As a professional mechanical seal manufacturer, we supply high-performance back to back mechanical seals built under ISO 9001 quality management system for pump and rotating equipment applications.

Back to back mechanical seal, also known as double mechanical seal, adopts two seal assemblies mounted opposite each other with barrier fluid between seal faces. This design delivers reliable leak-free mechanical seal performance, ideal for toxic, flammable, abrasive or hazardous process media where zero emission is required.

Our mechanical seal portfolio covers standard and custom sizes. We provide full support including mechanical seal installation guidance, technical consultation and competitive mechanical seal price. Each unit undergoes strict quality inspection to guarantee stable sealing, long service life and easy maintenance.
