Solid upgrade

Good product overall. The silicon nitride material is very hard and resistant. Make sure to verify your specific tonnage model before ordering, as the sizes vary significantly between the 10T and 150T versions.

Excellent durability for heavy use

We replaced our standard metal bushings with these silicon nitride sleeves on our 45T pump. The difference in wear resistance is noticeable after three months of continuous operation. Highly recommended for reducing downtime.

Reliable component

Purchased for a 150T unit. The surface finish is smooth, which helps reduce friction. No cracks or defects upon arrival. It performs exactly as described in the specifications.

Great quality, slightly pricey

The build quality is outstanding and clearly designed for industrial environments. While the price point is higher than alternatives, the extended lifespan justifies the cost. Took off one star only due to shipping time.

Perfect fit for 30T model

The dimensions were exact for our 30T mortar pump. Installation was straightforward, and the ceramic material handles the abrasive slurry much better than our previous components.
