HZT029150901 Pressure Chamber
316 Stainless Steel Casting · Marine Vacuum Pump Outlet Chamber · Corrosion-Resistant and Pressure-Resistant Structural Component
I. Descripción general del producto
The HZT029150901 pressure chamber (outlet chamber) is a key drainage component in the HZT 15MBD Marine Vacuum Sewage Pump* series. It efficiently discharges the gas-liquid mixture generated within the rotor chamber and serves as the final outlet component of the pump body.
It is entirely manufactured using a 316 stainless steel medium-temperature wax precision casting process. Its internal cavity features rounded corners to minimize fluid turbulence and energy loss. It also features an independent φ50 outlet port for direct connection to the ship’s discharge piping system or vacuum sewage collection system.
The HZT029150901, along with the HZT029150800 rotor housing,
HZT029150601 end flange, and HZT038201500 shaft seal, form the pump discharge assembly and are a core component of the HZT 15MBD / 25MBA series vacuum pump’s discharge section.
II. Material and Processing Characteristics
* Material: 316 stainless steel (Marine Grade 316SS)
* Excellent corrosion resistance, resistance to chloride ion attack, and resistance to stress corrosion;
* Particularly suitable for wastewater discharge systems such as those used in ships’ black water, gray water, and vacuum toilets.
* Manufacturing Process:
* Medium-temperature wax investment casting + CNC finishing;
* Internal flow channels feature smooth, rounded corners to reduce flow resistance;
* Surface sandblasting and electrolytic treatment creates a fine matte finish, enhancing corrosion resistance and assembly consistency.
* Quality Standards:
* Casting density ≥ 98%;
* No shrinkage cavities, sand inclusions, or bubbles;
* Dimensional tolerance control ±0.2mm;
* Passed a 480-hour salt spray test.
III. Product Features and Performance Advantages
✅ High Corrosion Resistance
Suitable for long-term seawater and wastewater contact environments, ensuring system life exceeds that of traditional carbon steel or 304 structural components.
✅ High-precision interface matching
The outlet size is φ50, conforming to standard marine discharge port dimensions, allowing direct connection to pipelines.
It is also compatible with components such as HZT029150601, HZT029150391, and HZT038201500.
✅ Optimized fluid structure
The internal channel features a smooth transition design, reducing flow loss and turbulent noise, and improving drainage efficiency.
✅ Modular design
Shares the same overall structure as the HZT 15MBD vacuum pump. Components in the same series (HZT029150320 suction chamber, HZT029150701 rotor, HZT029150800 housing) are modularly interchangeable, supporting OEM system upgrades or repair replacements.
✅ Stable pressure resistance and sealing performance
The seal with the HZT037221602 O-ring ensures a high vacuum seal and prevents leakage.
IV. Application Areas and Industry Coverage
* 🚢 Marine Vacuum Sewage System
* 🛳 Marine Black & Grey Water Disposal Unit
