Introduction To Common Mechanical Seal Models

1. HU1 type: HU1 type mechanical seal complies with ISO3096DIN24960 and GB6556 standards. The auxiliary seal volume can be selected according to the working conditions. Rubber "O" ring PTFE "V" ring of the same specification, single spring, unbalanced fork transmission, strong compensation ability, installation has nothing to do with the shaft rotation direction, friction pair material and auxiliary seal material can be selected according to actual working conditions.

2. HU3 type: HU3 type mechanical seal complies with DIN24960 and GB/T6556-94 standards, can replace 116U, 59U type mechanical seal, unbalanced, single end face structure, arbitrary rotation direction; various sewage pumps, chemical pumps, heat circulation pumps are applicable, spring options include: butterfly spring, multi-spring, etc.

3. HU5 type: HU5 type mechanical seal complies with DIN24960 standard, and back-to-back installation also complies with DIN24960 standard double-end mechanical seal. It belongs to partially balanced type, rubber bellows, single spring, single end structure. The dynamic ring is driven by the interference of the rubber bellows, with good floating performance, and the spring also plays the role of transmitting torque. Please select the friction pair material and auxiliary seal material according to the actual working conditions.

4. HU7 type: HU7 type mechanical seal complies with DIN24960 and GB/T6556-94 standards, can replace 108U type mechanical seal, unbalanced, conical spring structure, the rotation direction of the spring is related to the rotation direction of the shaft; the friction pair material and auxiliary seal material can be selected according to the actual working conditions, applicable scope: sealed medium: sewage pump, submersible pump, chemical pump, circulation pump, clean water pump and heating system.

5. HUU803: HUU803 mechanical seal complies with DIN24960 and GB/T6556-94 standards. It is unbalanced, with double-end faces of multi-spring structure and transmission sleeve transmission. The pressure of the sealing chamber must be 0.1-0.2Mpa higher than the medium pressure. Please select the friction pair material and auxiliary seal material according to the actual working conditions.

6. HBM1: HBM1 mechanical seal complies with DIN24960 standard. It is a single-end, balanced, and arbitrary rotation metal bellows seal. The dynamic ring O-ring and flexible graphite ring do not play a compensating role. Therefore, there is no resistance to the movement of the bellows, which is suitable for high temperature and high viscosity media. Please select the friction pair material and auxiliary seal material according to the actual working conditions.

7. HBM5: HBM5 mechanical seal is a single-end, balanced, rotary metal bellows mechanical seal. The moving ring part is connected to the sleeve as a whole. The whole set of mechanical seals is containerized, which simplifies the installation process. The pump is adjusted outside, making the installation of mechanical seals simpler. It is widely used in chemical, papermaking, sewage and other industries.

8. HQ901: HQ901 mechanical seal is an external, single-end, multi-spring, static, balanced structure. The spring does not contact the medium. The axial size is short. It can replace the skeleton oil seal. The containerized design simplifies the installation process and is simpler and more convenient to install (please select the friction pair material and auxiliary seal material according to the actual working conditions).
