When a rubber pump operates without a rubber pump seal, the liquid could leak out of the gear pumps between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this leakage can be difficult.
Rubber Pump Seal Feature:
1. Good elasticity
2. Good anti-ozone, anti-aging,
3. Good weather resistant,
4. Good fire and water resistant.
5. Convenient installation
6. Shiny appearance
7. Many colors are suitable.
8. Good tight dimensional tolerances and have excellent compressability,elasticity and adaptability to uneven surfaces.
Gear pump for screw extruder models used mechanical packing to seal the shaft. Since World War II, mechanical seals have replaced packing in many applications.
