Reliable Slurry Pump Rubber Throat Bush - Pumpmfr

Rubber Slurry Pump Throat Bush

The slurry pump rubber throat bush is a critical wear part that ensures the optimal performance of our SHR series rubber-lined slurry pumps. Precision-designed and crafted from high-quality natural rubber materials, this component is reliably used for handling abrasive or highly corrosive slurries containing fine solid particles without sharp corners. Other materials such as polyurethane, high chrome alloy, and ceramic are also available for throat bush liners to cater to diverse applications.

The rubber throat bush is an integral component, along with the frame and cover plate liner, and forms a complete pump chamber. This design ensures easy maintenance and proper guidance of the slurry into the impeller inlet while withstanding wear and corrosion. These replaceable liner parts play a pivotal role in enhancing the durability and efficiency of your pumping system. Manufactured in our factory in China, the product is available for wholesale at the best prices with short delivery times.

Features and Benefits

Abrasion Resistance: The rubber material used in the throat bush liner is selected for its excellent wear resistance when handling abrasive slurries containing fine, non-sharp particles, crucial for extending liner life and maintaining pump efficiency.

Corrosion Resistance: Rubber’s inherent resistance to corrosion makes it ideal for applications involving highly corrosive slurries, helping to prevent liner degradation and ensure the pump’s longevity.

Impact Resistance: The rubber throat bush liner is designed to withstand impacts from solid particles in the slurry. Its elasticity helps absorb impact energy, reducing wear.

Sealing Function: The liner enhances the sealing of the pump chamber, preventing slurry leakage and preserving the pump’s operational integrity, which is essential for avoiding contamination and maintaining efficiency.

Ease of Replacement: The lightweight, bolt-connected design of the throat bush facilitates easy replacement, reducing downtime and maintenance costs.

Cost-Effectiveness: With its lower cost compared to metal throat bushes, combined with benefits like lightweight, effective sealing, reduced noise, ease of replacement, and others, the rubber throat bush offers significant cost-effectiveness.
