I. نظرة عامة على المنتج
The HZT023280030 shaft seal flange is a key component of the HZT023280010 (25MBA marine vacuum sewage pump).
It is installed between the HZT038218900 (mechanical shaft seal) and the motor end cover. Its primary function is to provide stable positioning for the shaft seal’s static ring and form a high-vacuum end-face seal with the pump body.
This flange plays a crucial role in supporting the seal during overall pump assembly. It ensures the mechanical seal’s static ring’s compression and alignment, ensuring stable sealing performance even under high-speed rotation and vacuum conditions, preventing gas or liquid leakage.
II. Structure and Materials
| Component Name | Material | Process Description |
| —- | —————– | ————————- |
| Flange Body | 316 Stainless Steel (AISI 316) | Entirely precision CNC machined for corrosion resistance, rust resistance, and high fatigue strength |
| Seal Groove | Machined and fine-turned | Internally precision-turned for O-ring installation (NBR/EPDM) |
| Connecting Surface | CNC precision end face machining | Ensures a perfect fit with the HZT038218900 mechanical seal stationary ring |
| Fixing Method | Four-point symmetrical bolt locking | Provides uniform preload to prevent assembly misalignment and leakage |
Processing Features
* Full CNC machining
* Surface roughness Ra ≤ 0.8μm
* Guaranteed dynamic seal system coaxiality ≤ 0.03mm
* Optimized for vacuum and negative pressure environments
III. Assembly and Fitting
The HZT023280030 serves as the shaft seal support flange. Its front end mates with the **HZT038218900 mechanical shaft seal stationary ring and its rear end connects to the motor end cover, forming the shaft seal support.
In the entire pump body, it mates with the following components:
* 🔹 HZT023219000 (Rotor Housing)
* 🔹 HZT023260400 (Distance Sleeve)
* 🔹 HZT023219100 (Pressure Chamber)
* 🔹 HZT021265401 (Rotor)
The O-ring (e.g., HZT037219260) seal groove inside the flange mates with the shaft seal outer ring, ensuring a reliable and leak-free sealing system.
IV. Performance Features
1. High Sealing Precision – Precision-machined seal grooves and flange surfaces ensure precise positioning of the mechanical seal’s static ring, preventing eccentricity and cavitation.
2. Corrosion-resistant 316 stainless steel construction – Resists seawater corrosion and blackwater acid and alkali erosion, with a lifespan over three times greater than that of ordinary carbon steel.
3. High Vacuum Holding Strength – Ensures the HZT023280010 operates stably and long-term at -0.09 MPa vacuum.
4. Modular Installation – Standardized interface dimensions facilitate maintenance and replacement, compatible with all HZT25MBA series models.
5. Wide Applicability – Suitable for use in ships, yachts, offshore platforms, and land-based vacuum sewage systems.
5. Typical Applications
The HZT023280030 is the core connector in the entire HZT25MBA Marine Vacuum Discharge Pump** seal structure and is primarily used for:
* 🚢 Marine & Yacht Vacuum Sewage Systems
* 🛳 Offshore Vacuum Collection Units
* 🧱 Land Vacuum Toilet Systems
* ⚙️ Vacuum Pump Stations / Sewage Stations
