HZT029150601 – 15MBD Marine Vacuum Sewage Chopping Pump with End Flange (316 Stainless Steel Casting) | HZT OEM Marine Sewage and Wastewater Vacuum System Intermediate Connection Kit Compatible with JETS

The HZT029150601 end flange is the rear-end connection component of the HZT 15MBD Marine Vacuum Sewage Pump System. Manufactured from a single piece of 316 stainless steel using a medium temperature wax casting process and sandblasted and electrolytic polished finish, it offers excellent corrosion resistance, compressive strength, and long-term stability.

Serving as the fixing and sealing interface between the suction chamber (HZT029150320) and the main pump body, the HZT029150601 utilizes bolts and an O-ring sealing structure to create a secure and airtight connection, ensuring the vacuum chamber remains leak-proof and deformation-free even under high negative pressure, providing stable mechanical support and vacuum sealing performance for the entire system.

I. Structural and Manufacturing Advantages

* Integral precision casting: Crafted from 316 stainless steel, it features seamless internal and external welds and stress-concentration points, enhancing pressure resistance.
* Surface treatment: Sandblasting and electrolytic treatment create a dense passivation film, effectively preventing seawater corrosion and salt spray oxidation.
* High-precision sealing groove: The sealing surface is CNC-machined for a perfect fit with the O-ring, ensuring a dual gas-liquid seal.
* Stable structure: Withstands reverse negative pressure and mechanical stress during vacuum operation, maintaining coaxiality and rigidity between the suction chamber and the main pump chamber.
* High maintainability: Easy assembly and disassembly, reliable sealing, and suitable for regular maintenance on vessels in long-term operation.

II. Function and System Role

HZT029150601 is the end connection flange of the vacuum pump structure. Its main functions are:

* Secures the suction chamber to the main pump body, achieving mechanical closure and a sealed transition;
* Withstands the reverse impact and pressure fluctuations of the gas-liquid mixture;
* Maintains the overall seal and structural alignment of the vacuum suction system;
* Serves as the rear interface of the vacuum inlet section, connecting to the downstream piping system.

This component is a critical mechanical support and sealing core for the long-term stable operation of the 15MBD marine vacuum pump system.

III. Industry Applications and System Expansion

The HZT029150601 is widely used in:

* 🚢 Marine Sewage & Black Water Vacuum Collection System
* ⚙️ Marine Vacuum Toilet System
* 🛳️ Offshore Wastewater Treatment Unit
* 🧰 Shipboard Sanitation & Wastewater Transport System

Its high-strength 316 stainless steel construction and tight sealing properties ensure long-term reliable operation in humid, high-salt, and high-negative-pressure marine environments, making it an essential core vacuum pump component for ships and offshore equipment.

IV. Technical Standards and Testing

The HZT029150601 end flange strictly complies with ISO 9001 and ISO 8099-1:2018 international standards for ship sewage discharge systems and has passed the following tests and certifications:

* Vacuum & Pressure Resistance Test
* Salt Spray Test
* Passivation Layer Thickness Test
* CNC Tolerance Test

HZT consistently adheres to high manufacturing standards to ensure that every vacuum system component meets international maritime equipment quality requirements.
