Mirror polished eductors for hygienic manufacturing

When a pharmaceutical manufacturer needed mirror polished tank mixing eductors for three new tanks, they called Tecpro Australia to provide a solution for their exact requirements.

The challenge

A pharmaceutical manufacturer was commissioning three new 57,000 L tanks that measured 6 m high x 3.5 m diameter.

Each tank required two mixing eductors with an integrated insertion lance. To meet the exacting hygiene standards of the manufacturing process, the eductor and lance required mirror polishing internally and externally. The minimum required surface finish specifications were 0.8 microns RA.

Specialised hygienic clamp fittings were also required to prevent any bacterial build-up.

The solution

Tecpro had to get creative in order to achieve the required mirror polish finish.

Small sections of the insertion lance were cut, mirror polished internally and externally, then welded back together.

Before the tank could be commissioned, the materials, surface polish and weld points were all inspected and certified as achieving the required ultra-hygienic standards. All three tanks are now operating.

Tecpro Australia is a specialist engineering supplier that works across a broad range of industries. It provides off-the-shelf solutions as well as design, fabrication and consulting expertise for customers requiring unique solutions such as the ultra-hygienic, mirror polished eductors and insertion lances for this project.
