1. Single-End Balanced Mechanical Seal

Adopts a balanced structure and self-compensating design with pressure-adaptive adjustment capability, delivering outstanding performance in general applications. Its advantages include:

Long-Term Operation: Automatic wear compensation on dynamic sealing surfaces increases service life by over 40% compared to non-balanced types.

Broad Compatibility: Designed for standard-viscosity fluids. Typical media include tomato sauce, peanut butter, emulsions, shampoo, syrup, and yogurt beverages in daily chemical and food industries.

Cost Efficiency: Simplified maintenance reduces overall operational costs by 30%.

Application Scenarios: Daily chemical production lines, food filling systems, pharmaceutical fluid transfer.

2. Double-End Water-Cooled Mechanical Seal

A dual-protection system for extreme conditions, integrated with external flushing and cooling, specifically for hazardous media:

Dual Barriers: Two-stage sealing faces form a physical isolation chamber to effectively block hazardous fluid leakage.

Active Temperature Control: Circulating coolant maintains seal cavity temperature below 80℃, preventing media solidification or decomposition.

Hazardous Media Handling: Suitable for fluids with viscosity >50,000cP, solid content >25%, or toxic properties. Typical media include molten chocolate, mortar, PVC adhesive, photosensitive emulsion, resin, and Class III+ hazardous chemicals.

Application Scenarios: Chemical waste treatment, building material mortar pumping, specialty material synthesis.

3. Bellows Mechanical Seal

Innovative metal bellows structure overcomes traditional spring limitations, providing triple advantages:

Elasticity Advantage: Maintains sealing face conformity even with 0.5mm shaft eccentricity, eliminating partial-wear leakage risks.

Strength Breakthrough:

oUltra-High Pressure Resistance: Multi-layer stainless steel bellows significantly enhance burst pressure tolerance.

oFatigue Resistance: Sealing face deformation remains minimal after 500,000 pressure pulsation cycles.

Stiffness Characteristics:

oRigidity-Flexibility Balance: Exceptionally high axial stiffness coefficient ensures resistance to medium pressure fluctuations at high temperatures.

oAnti-Micro-Vibration Design: Extremely low leakage rate (<5mL/h) under high-frequency vibration (0.2mm amplitude).

Application Scenarios: High-temperature thermal oil transfer, refinery heavy oil processing.

Bonve will always uphold the philosophy of "wholeheartedly dedicated to rotor pumps", committing to providing global customers with customized conveying and mixing solutions.
