I. Product Positioning (Model + Function + Support)
The HZT023219000 rotor housing is a key fixture in the HZT 25MBA marine vacuum discharge pump. Its core function is to create a stable high-vacuum chamber and provide precise coaxial rotation for the rotor HZT021265401. This housing mates with multiple components within the 25MBA series:
* Front: Mate with the HZT023200210 End Plate Suct. Chamber (suction side)
* Rear: Mate with the HZT023280030 Flange (shaft seal end flange/rear flange)
* Axial sealing/locating: Mate with the HZT038281900 Shaft Seal (shaft seal) and the HZT023260400 Distance Sleeve (distance sleeve)
* This housing has a specific geometry and interface for the 25MBA and is not interchangeable with the 15MBD series.
II. Materials and Manufacturing
* Material: Marine-grade 316 stainless steel, offering corrosion resistance, strength, and fatigue resistance, suitable for marine and shore-based environments subject to high humidity, salt spray, and oily contaminants. * Manufacturing: CNC machining of the entire blank (inner bore, end face, seal groove, and flange face are all performed in a single process of positioning and finishing), ensuring inner roundness, end face accuracy, and concentricity.
* Surface: The inner wall is smooth, enhancing the stability of the gas-liquid mixed flow; the outer surface can be sandblasted or electropolished upon order to enhance corrosion resistance and cleanability.
* Dimensional Stability: Controlled assembly datums ensure low vibration and high sealing performance even when mated with the dynamically balanced rotor (HZT021265401).
III. Structure and Technical Features
1. High Vacuum Sealed Chamber
O-ring seals are reserved on the inner bore and end face, working in conjunction with the HZT038281900 (shaft seal) and corresponding O-rings to create a stable negative pressure chamber.
2. Coaxial and Axial Positioning
Compatible with the HZT023260400 (spacer sleeve) to control axial clearance; the flange surface of the HZT023280030 (rear flange) ensures coaxiality between the motor shaft, rotor, and housing.
3. Heavy-Duty/High-Flow Compatibility
Compatible with the increased rotor length and spiral geometry of the HZT021265401, it is suitable for vacuum pumping applications requiring higher flows and torques (multi-chamber systems and long-distance pipeline networks) than the 25MBA.
4. Maintenance-Friendly
Standardized flange and seal design facilitates periodic disassembly and inspection; it is compatible with other 25MBA series components, minimizing downtime.
IV. Application Areas
* Marine & Yacht Vacuum Discharge / Sanitation Systems (Blackwater/Graywater Vacuum Collection)
* Offshore Platforms: Offshore Vacuum Collection Unit, Rig Sanitation Module
* Ports/Shore-Based Systems: Harbor/Port Vacuum Station, Ship-to-Shore Discharge
* Land-Based Vacuum Toilet Systems: Land-Based Vacuum Toilet / Sewage Collection (Residential, Campsite, Scenic Area, Transportation Hub)
> Combined with HZT021265401 (Rotor), HZT023280030 (Flange), HZT023200210 (End Plate), HZT038281900 (Shaft Seal), etc.
> This constitutes the key assembly of the 25MBA pump head, maintaining extremely low noise, low vibration, and high vacuum in high-load operating environments both at sea and on land.
V. Selection and Maintenance Recommendations (Simple and Practical)
* Specificity: Compatible only with HZT 25MBA geometry and interfaces; not interchangeable with 15MBD.
* Assembly: It is recommended to strictly follow the 25MBA process diagram to control axial clearance and seal ring compression, and verify coaxiality.
* Maintenance: Periodically inspect O-rings and shaft seal HZT038281900 for wear and aging. If abnormal vibration is detected, verify rotor dynamic balancing and bearing condition.
* Retrofit/Replacement: In EVAC/JETS system upgrades and retrofits, this product can be used as a housing base component for 25MBA solutions, provided that the interfaces and flange surfaces are compatible with adapters.
