The HZT029150310 suction chamber cover is a critical structural seal in the HZT 15MBD marine vacuum sewage pump system. Made of high-strength transparent PMMA (Polymethyl Methacrylate) material, this cover offers excellent light transmittance and corrosion resistance, ensuring reliable sealing and visual monitoring within the vacuum sewage system.
In the pump structure, the HZT029150310 is assembled with the HZT029150320 suction chamber, with an HZT037219210 O-ring inserted between them. Eight fastening bolts secure the cover evenly, creating a stable seal that prevents air leakage and sewage seepage, thereby ensuring stable vacuum system pressure and safe operation.
I. Structural and Performance Advantages
* Material Advantages: PMMA acrylic offers excellent transparency (up to 95% light transmittance), allowing intuitive observation of the pump chamber’s internal operating conditions, facilitating maintenance and troubleshooting.
* Sealing Design: Precision-machined O-ring grooves ensure a perfect seal fit, providing long-lasting leak-proof protection.
* Fixing Structure: 8 bolts are evenly distributed to prevent cover deformation due to uneven force, improving airtightness and pressure resistance.
* Environmental Resistance: Resistant to seawater, acids, alkalis, and UV rays, it is suitable for long-term use on ships and offshore platforms.
* Visual Function: The polished, transparent cover facilitates routine inspection and maintenance, allowing inspection of the valve chamber without disassembly.
II. Technology and Applications
The HZT029150310 suction chamber cover is widely used in:
* Marine sewage vacuum systems
* Offshore wastewater treatment units
* Vacuum toilet systems and collection units
* Marine pump maintenance and OEM integration
All HZT PMMA products undergo pressure resistance testing, vacuum sealing testing, and impact resistance verification to ensure stable transparency and crack resistance even under high loads.
III. Product Compatibility
The HZT029150310, along with the following components, forms a complete suction chamber sealing system:
* HZT029150320 — Suction Chamber
* HZT037219210 — O-Ring
This combination is specific to the 15MBD series and is not compatible with the 25MBA. However, the 25MBA series shares common structural components, making it easier for customers to identify and purchase.
IV. Brand and Standards
HZT specializes in the design, manufacture, and testing of core components for marine vacuum sewage pump systems. All PMMA parts have passed salt spray resistance, vacuum sealing, and aging tests, complying with the ISO 8099-1:2018 international standard for sewage discharge from ships.
With its transparency, corrosion resistance, and high-precision assembly, the HZT029150310 is an indispensable safety sealing component in marine vacuum pump systems.
