Detailed introduction

The ZU series mechanical seals are specially designed for highly corrosive, highly abrasive chemical and desulfurization environments. They offer reliable sealing performance and broad versatility, making them the preferred solution for harsh industrial operating conditions.
✅ Core Advantages and Parameters
▶ Excellent corrosion resistance: The base material can be selected from SUS316L, 2205, 2507, and other materials, offering outstanding resistance to chloride ions and erosion by gypsum slurries.
▶ Long service life and low leakage: Optimized end-face mating and compensation mechanisms ensure a service life superior to that of conventional seals. Precision end-face grinding technology delivers extremely low operating leakage, guaranteeing that process media remain securely contained and do not cause contamination.
▶ Customized Materials: Some models support customization with duplex stainless steel substrates such as 2205 and 2507, making them suitable for special operating conditions.
✅ Structural features
▶ Single-end face fork drive: compact structure, easy installation, and independent of rotation direction;
▶ Multiple types of auxiliary sealing rings: Rubber O-rings and PTFE V-rings/wedge rings can be selected according to operating conditions, making them suitable for a variety of media.
▶ Standardized design: Complies with ISO3069, DIN24960, and GB6556 standards, offering high versatility and easy interchangeability;
▶ Modular design: internal mounting, internal flow, single-spring, unbalanced design, fork-slot transmission—easy to maintain.
✅ Applicable scenarios
▶ Main application scenario: Side-mounted agitator for flue gas desulfurization absorption towers in coal-fired power plants (handling high-solid-content media such as gypsum and lime slurry);
▶ Expansion of Application Areas: Chemical reactors (sealing for stirred tanks used in the processing of strong acids and strong bases such as sulfuric acid, hydrochloric acid, and chlor-alkali), non-sterile-grade reaction systems for pharmaceutical and biotechnology applications (meeting CIP cleaning requirements and preventing cross-contamination), and high-fiber/high-viscosity medium transfer pumps and mixing equipment for the pulp and paper and wastewater treatment industries.
