HZT023280040 Chambre d'aspiration - 25MBA Marine Vacuum Sewage Pump Chambre d'aspiration frontale | 316 Stainless Steel Precision Cast Construction | High-Efficiency Vacuum Flow Path Design

I. Présentation du produit

The HZT023280040 suction chamber is the core front-end component of the HZT023280010 (25MBA marine vacuum sewage pump). It draws the gas-liquid mixture of sewage, black water, or domestic water from the pipeline system into the pump body and guides it into the HZT023219000 (rotor housing) for vacuum transmission.

This component utilizes a monolithic casting process for 316 stainless steel. Its internal flow path is designed using fluid simulation and optimized vacuum resistance. This ensures high vacuum suction and high flow stability even under strong negative pressure conditions. It is a key component in the rapid vacuum formation of the entire unit.

III. Function and Performance

1️⃣ High vacuum suction efficiency
The internal streamline structure of the suction chamber was analyzed using CFD (Computational Fluid Dynamics) Dynamics) optimization maximizes negative pressure generation efficiency, improving vacuum response speed by approximately 20% compared to traditional structures.

2️⃣ Corrosion-resistant 316 stainless steel construction

Suitable for complex media such as seawater, black water, and domestic sewage, preventing electrochemical corrosion and cracking during long-term operation.

3️⃣ Reliable sealing design

Combined with an O-ring (HZT037219210), the pump’s internal vacuum is completely isolated from the external environment.

4️⃣ Easy assembly and maintenance

Slips into the HZT023219000 rotor housing, and a dual-hole fastening structure allows for quick alignment.

5️⃣ Multi-system compatibility

Compatible with both the HZT25MBA and HZT25MBA-02 variant pumps, ensuring strong compatibility and easy maintenance.

IV. Typical Mating Components

* 🔹 HZT023219000 — Rotor Housing
* 🔹 HZT023219100 — Pressure Chamber
