Description
The kit includes high‑quality GX vanes. These are known for lasting longer and performing better than standard vanes. You also get a full set of bearings, shaft seals, gaskets, and O‑rings. Plus, we’ve added new inlet and outlet filters. Every piece is made to match the original Busch specifications for the 0400B model. They fit perfectly, so your pump seals tightly and runs smoothly again
