HZT037219SET O-Ring Seal Kit | EPDM Seal Kit for 25MBA Marine Vacuum Sewage Pumps, Compatible with Mainstream Vacuum Systems (Marine, Yacht, Vacuum Toilet, and Sewage Systems)
1. Visão geral do produto
The HZT037219SET O-Ring Seal Kit consists of four separate components (HZT037219260, HZT037219280, HZT037219220, and HZT037219200) and is a complete set of key sealing components for the 25MBA marine vacuum sewage pump. This set is used to seal the connections of the suction chamber (HZT023280040), pressure chamber (HZT023219100), rotor housing (HZT023219000), and mechanical seal (HZT038218900), ensuring long-term, leak-free operation in high vacuum and blackwater environments.
This set is designed specifically for marine vacuum discharge pumps and vacuum toilet systems. It is compatible with a variety of mainstream international vacuum system configurations and serves as a standard replacement for routine maintenance and refurbishment.
2. Materiais e artesanato
The O-rings are made of EPDM (ethylene propylene diene monomer) high-molecular-weight elastomer, offering excellent resistance to heat, seawater, blackwater, acids, and alkalis. They can operate in hot and humid environments ranging from 0°C to 90°C for extended periods. EPDM has low compression set and excellent resilience, resisting deformation and leakage under vacuum.
Each O-Ring undergoes precision molding, deburring, and dimensional inspection to ensure that the inner diameter, cross-section, and elasticity meet ISO/Marine Vacuum quality standards. The sealing rings tightly mate with stainless steel contact components (such as the HZT023280061 valve seat and the HZT023280040 suction chamber flange), achieving a surface finish of Ra0.8 or higher, ensuring a reliable seal.
3. Structural and Functional Features
The HZT037219SET covers several key sealing points in the 25MBA vacuum pump system:
a) HZT037219260 mates with the suction chamber (HZT023280040) to ensure an inlet seal.
b) HZT037219280 serves as the interface between the pressure chamber (HZT023219100) and the rotor housing (HZT023219000). c) HZT037219220 is combined with mechanical seal HZT038218900 to prevent shaft seal leakage.
d) HZT037219200 is suitable for sealing the pump cover and motor connection.
Through this structural combination, the O-ring set forms a fully enclosed vacuum seal chain during operation, effectively reducing energy consumption, extending pump life, and reducing maintenance frequency.
4. Aplicações
This seal set is widely used in:
a) Vacuum sewage discharge systems for ships, yachts, passenger ships, and commercial vessels.
b) Vacuum sewage and domestic sewage treatment for offshore platforms, drilling vessels, and FPSOs.
c) Vacuum toilet systems for recreational vehicles (RVs), mobile toilets, and land-based buildings.
d) Municipal sewage vacuum collection and environmental protection projects.
e) Water-saving sanitation systems and eco-friendly camping facilities. Due to its flexible and corrosion-resistant NBR material, it is suitable for environments containing saltwater, blackwater, and chemical wastewater, ensuring long-term stable operation under continuous operation.
5. Compatibility and Adaptation
The HZT037219SET is the standard maintenance seal kit for the 25MBA series vacuum pumps and is compatible with the following components:
* HZT023280040 Câmara de aspiração
* HZT023219100 Câmara de pressão
* HZT023219000 Rotor Housing
* HZT038218900 Shaft Seal
In addition, the seal’s geometry is compatible with the JETS standard interface of many mainstream international vacuum systems, making it suitable as a replacement for mainstream brands of marine vacuum systems, yacht sanitation systems, vacuum toilets, and sewage transfer systems. (Brand names are not directly marked to avoid copyright infringement.)
6. Resumo profissional
The HZT037219SET O-ring seal set is a specialized maintenance kit for the 25MBA vacuum sewage pump system. Made from high-performance NBR material, it offers excellent sealing, corrosion resistance, and fatigue resistance. This set completely replaces critical sealing points on the pump body, effectively ensuring system vacuum levels and water conservation, extending the life of the pump. Whether used in marine, yacht, passenger ship, RV, or land-based vacuum toilet systems, it provides a reliable vacuum sealing solution.
