NBR Nitrile Rubber · High Vacuum Sealing Performance · Specialized Sealing Components for Marine Vacuum Pumps
I. Produktübersicht
The HZT037219210~HZT037221602 O-Ring Seal Set is the core sealing component for the HZT 15MBD marine vacuum sewage pump. Made of NBR nitrile rubber, this series of O-rings is specifically designed for the gas-liquid isolation system of vacuum pumps. They ensure reliable sealing and leak-proof operation in high-pressure, high-humidity, and corrosive environments.
This seal assembly covers key sealing areas of the pump body, including:
* Between the suction chamber (HZT029150320) and the suction chamber cover (HZT029150310);
* Between the end flange (HZT029150601) and the pressure chamber (HZT029150901);
* Between the shaft seal (HZT038201500) and the shaft seal end flange (HZT029150391);
* The connection area with the rotor housing (HZT029150800);
* As well as the outlet chamber and vacuum pipe interface.
II. Material Characteristics and Performance Advantages
Material: NBR (Nitrile Rubber)
1. High Sealing Performance
NBR rubber has excellent elasticity and resilience, maintaining seal integrity under alternating vacuum and positive pressure conditions.
2️⃣ Media Resistance
Suitable for a variety of media, including black water, gray water, lubricating oil, condensate, and seawater.
Excellent resistance to oil, salt spray, acids, and alkalis.
3️⃣ High Temperature and Aging Resistance
Operating temperature range: -30°C to +120°C; no cracking or hardening after long-term use.
4️⃣ Precision Fit
O-ring dimensions are precisely dimensioned and aligned with the tolerances of all HZT vacuum pump components, ensuring that compression and sealing gaps remain within ideal ranges during assembly.
5️⃣ Vacuum Deformation Resistance
Maintains a stable cross-sectional shape even under strong negative pressure, preventing flattening or displacement.
III. Compatible Components and Assembly Locations
| Material Code | Name | Functional Location |
| ———— | ———– | ———– |
| HZT037219210 | O-ring | Shaft seal assembly and end flange seal |
| HZT037219220 | O-ring | Suction chamber cover seal |
| HZT037219250 | O-ring | Pressure chamber and end flange seal |
| HZT037219200 | O-ring | Flap valve base and suction chamber seal |
