[Case Study] Transport of a liquid that hardens upon exposure to air

Solving the issue of "hardeners sticking due to exposure to air, causing pump failures" at the foundry manufacturer!

The request from the casting manufacturer was to add a hardener to the sand in the process of making sand molds for casting. However, there was a challenge where the hardener leaked from the pump's shaft seal, came into contact with air, and hardened, causing the pump to fail. The hardener was supplied using a gear pump, and the injection amount was controlled by an electromagnetic valve. For the solution to this issue, please download and refer to the PDF materials. 【Customer's Issue】 ■ The hardener leaking from the pump's shaft seal comes into contact with air and hardens, causing the pump to fail. *For more details, please refer to the PDF materials or feel free to contact us.
