User Success Story: Finding a Solution for Difficult to Transfer 40,000 mPa・s Dielectric Liquids with Smoothflow Pumps

We decided to introduce a high viscosity dielectric, but we were racking our brains trying to come up with a transfer solution.

Problems: Urgent need to be able to handle 40,000 mPa・s High Viscosity Liquid.

Company I, a chemical manufacturer, manufactures dielectrics for ceramic capacitors. Mr. K, the factory manager, was being bothered by one particular problem.

“To accommodate to customer’s needs, we decided to produce a new dielectric, but the viscosity of this new dielectric was about 40,000 mPa・s, which was magnitudes higher than our past products.”

Mr. K tested a rotary type metering pump which is strong against high viscosity liquids, but due to the ceramic slurry, the sliding parts wore out quickly, contamination (mixing of foreign matter), and reductions in the flow rate occurred. For these reasons, Mr. K decided to give up on using a rotary type pump and searched for a pump that could satisfy his requirements.

Problem Points:

・Send a dielectric with a viscosity of 40,000 mPa・s without contamination or reductions in the amount of flow.

Solution:

-Consulted with Tacmina after remember a pump he had used in the past.

Mr. K recalled about a time that a pump from Tacmina had been adopted while he was working in a different department in the past. “The sales person who corresponded with me at that time kindly consulted with me about that application.”

So Mr. K decided to immediately reach out to Tacmina again. Shortly after that, Mr. K brought in an actual sample of his dielectric solution to Tacmina’s Liquid Solution Center to perform an actual test with a high-viscosity specification Smoothflow Pump.

“Since the Smoothflow Pump is structurally free of mechanical seals and there is no risk of leakage, we had hope that we would be able to transfer this liquid with this pump.

However, even with the superior performance of this pump, the 40,000 mPa・s high viscosity liquid proved to be a formidable foe. As a result of the test, cavitation occurred and their desired flow rate did not come out.

-Successfully transferred the high viscosity fluid with a new type of Smoothflow Pump.

Mr. K, even with an actual liquid test, ran into another wall and was further puzzled by the problems with his application. However, Tacmina’s salesperson contacted Mr. K again and told him that Tacmina wanted to challenge the problem again, and Mr. K was kind enough to listen to our proposal.

This proposal was for the release of a new Smoothflow pump optimized for transporting highly viscous liquid which had been in the making after years or research. This new type of pump, in addition to having all of the good parts of traditional diaphragm pumps (no sliding parts, low wear and contamination risks), was created with a newly designed check valve, which is the key to this liquid transfer, and it was able to stably transfer the high viscosity liquid which was considered difficult to transfer with reciprocating pumps. Immediately after reviewing the piping design and testing the pump, the new type Smoothflow Pump was able to successfully transfer the high viscosity liquid at the desired flow rate. Thanks to this pump, Mr. K was able to start productions on his new dielectrics line.

Solution Points:

・Capable of handling the transfer of 40,000 mPa・s high viscosity liquid by reviewing the design of the piping connection and using a high viscosity specification Smoothflow pump.
