Solve 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 create sand molds for casting by adding a hardener to the sand during the manufacturing process. However, there was a challenge where the hardener leaked from the pump's shaft seal, came into contact with air, and solidified, 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 Challenge】 ■ The hardener leaking from the pump's shaft seal comes into contact with air and solidifies, causing the pump to fail. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
Takumina Co., Ltd. is a leading company in precision pumps and a provider of "fluid solutions" that welcomes all challenges. With a history of over 67 years since its founding, it is a long-established manufacturer that was the first in Japan to start producing powered metering pumps. Before the widespread adoption of water supply systems, we began manufacturing and selling suction-type chlorine sterilizers, and the difficult challenges faced by our customers have shaped Takumina's "pump technology" over the years. Currently, our pumps are continuously chosen for various manufacturing processes that require high precision, including electronic materials, pharmaceuticals, and more. Our smooth flow pumps, which provide high-precision liquid delivery with continuous, pulsation-free flow despite being diaphragm-type, are strong against slurries, contamination-free, and do not change liquid quality. We offer fluid solutions used in various manufacturing, transfer, supply, and injection processes, starting with the water treatment field. At Takumina, we strive daily to understand the properties of liquids and the conditions of processes to propose the optimal transfer systems. We provide suggestions from research and development to manufacturing processes. We also accept inquiries for rental equipment and actual liquid testing. If you have any difficulties in selecting pumps or fluid transfer, please feel free to contact us.
