[Example] Transport of doping solution in a chemical plant

[Example] Transport of doping solution in a chemical plant

Due to the mechanical seal, there is no need to re-tighten the shaft seal section! This is a case that has increased confidence against foreign matter contamination and dry running.

The pump that the customer was using had a shaft seal with a gland packing, which required regular tightening and could not operate dry, leading to certain issues. Therefore, we proposed the Nakakin Rotary Pump "JM Series." This product uses a mechanical seal, eliminating the need for tightening at the shaft seal, thus reducing labor costs and time spent on maintenance. 【Case Overview】 ■Issues - Cannot operate dry - Requires regular overhaul by swapping with a backup unit ■Proposed Product: Nakakin Rotary Pump "JM Series" - Capable of transporting low to high viscosity liquids - Low risk of foreign substances entering due to non-contact operation *For more details, please refer to the related link page or feel free to contact us.
