Rubber
Throat Bush
Overview
The Kingda Rubber Throat Bush plays a crucial role in slurry pumps by serving multiple functions that enhance pump performance and longevity. Designed and manufactured with precision by Kingda, its primary function is to protect the pump body from wear and corrosion caused by solid particles in the slurry, which can be highly abrasive. This protection helps extend the lifespan of the pump body.
Additionally, the Kingda Rubber Throat Bush helps reduce gap wear by minimizing friction between solid particles and the pump surfaces. By decreasing the gap between components, it prevents excessive wear and ensures consistent pump efficiency.
Furthermore, a well-designed Kingda Rubber Throat Bush optimizes flow and head by reducing resistance during slurry movement. This improvement enhances overall pump efficiency while minimizing energy consumption.
Kingda Spares & Parts
Kingda Pump Group offers end-to-end spare parts manufacturing capabilities, covering all critical slurry pump components. Our production process begins with precise design to ensure that every part meets industry standards for dimensions, shape, and materials. With advanced manufacturing techniques and rigorous quality control, we guarantee the durability and wear resistance of essential components like bearing assemblies, frame plates, impellers, liners, and throat bushes.
Slurry Pump Wear Parts
Rubber Material
High Wear Resistance
Rubber materials are especially suitable for handling abrasive slurries, particularly in environments with a high concentration of solid particles. The elasticity and wear resistance of rubber help extend the life of the Throat Bush, reducing the frequency of maintenance and replacement.
Corrosion Resistance
Certain rubber materials (such as neoprene, polyurethane, etc.) offer excellent resistance to chemical corrosion, making them ideal for handling corrosive slurries.
Lower Costs
Compared to metal throat bushes, rubber throat bushes are more cost-effective, offering better sealing properties and shock resistance, which reduces maintenance costs and downtime.
Reduced Noise and Vibration
The flexibility of rubber helps absorb some of the vibrations, reducing pump operating noise and improving the working environment.
