What is Tacmina's stragegy for responding to this type of request?
Chemical Manufacturer H Company
"I want to send dangerous hydrogen peroxide water over a long distance and with a high lift! What is Tacmina’s strategy for responding to this type of request?"
Surfactant is widely used in detergents, ingredients of pharmaceuticals and cosmetics. Company H was struggling to select a pump to transfer a hydrogen peroxide solution, which is a raw material for Company H.
“I cannot find a pump that can strictly cope with the high pressure transfer conditions for long-distance piping for hydrogen peroxide water…”
In order to run a new plant to produce surfactant, Company H needed a pump to transfer a hydrogen peroxide solution at a rate of 1L/min.
There were 2 conditions required for the pump. The first, which was specified by Company H, was that the liquid-end materials of the pump had to be PTFE. The second condition was that the discharge pressure of the pump had to be above 0.7MPa. The distance from the chemical tank to the injection point was about 180m and the height difference was 15m. Since the injection point was a reaction kettle, the pressure required for the pump was above 0.7MPa.
Mr. N, who was responsible for the production department, searched for a pump that satisfied these two conditions.
“There was a rotary pump that had a discharge pressure of 0.7MPa or greater, but we could not find one with PTFE liquid-end materials. Next, we looked at diaphragm type pumps, but because they had pulsation, it was necessary to install an air chamber to alleviate the pulsation. However, since high concentration hydrogen peroxide solutions are very dangerous, we did not want to use an air chamber due to the risk of rupture.”
Is it possible to find an ideal pump that satisfies the needs of Company H?
・Specified PTFE materials for the liquid-end parts of the pump.
・For the transfer, the discharge pressure needs to be at least 0.7MPa.
We customized the liquid-end parts of the pump to response to the customer’s request, and we were able to clear the 0.7MPa discharge pressure with PTFE.
Mr. N, who was struggling to find a pump, was actually using one of Tacmina’s Smoothflow pumps in another plant of the same company. Although it is a diaphragm type pump, it has a structure that does not create pulsation, so he knew that it would not be necessary to install an additional air chamber.
“I thought they could help us find a solution to this problem, so I immediately contacted a Tacmina salesperson.”
PTFE liquid-end materials had been used in Tacmina’s Smoothflow pumps for a while, but the standard specifications of the max. discharge pressure was only 0.5MPa.
“But Tacmina suggested customizing a pump to satisfy the desired discharge pressure.”
In addition to the pump head, diaphragm, check ball, valve seat, and pipe fitting, even the attachment part of the liquid-end parts’ design was re-examined and improved. As a result, it was able to clear the 0.7MPa discharge pressure brilliantly.
“To be honest, I thought it was going to be inevitable that we start looking into materials like stainless steel for this application, but Tacmina was able to make the pump for us exactly how we wanted it.”
As a results the new plant installed the Smoothflow pump, and the pump has been prepared for operation.
・Proposed a Smoothflow Pump made of PTFE materials.
・After customizing the liquid-end parts, the required 0.7MPa discharge pressure was achieved.
