The customer used a metal coolant pump to transfer an abrasive slurry liquid. They had to replace the pump frequently because the impeller was heavily worn out with the slurry. So they asked us to develop an abrasive-strong pump.
We recommended a resin material for a solution to transfer this rigid slurry liquid. We repeatedly worked on designing and trials, emphasizing a strong resistance to this special slurry and “perfect seal-less” by achieving seal-less, and no bearing metal as well.
The customer highly evaluated the excellent abrasiveness of our developed pump and decided to adopt it.
