The pump is equipped with "Non-Contact Shaft Seal Mechanism" patented in USA, UK, Japan and other countries.
With this mechanism, the rotating unit and the stationary unit of the shaft seal device do not contact each other whether the pump is stopped or in operation.
Moreover, they maintain an appropriate sliding surface gap, create a predetermined amount of leakage, and do not allow contaminants and impurities into the pump.
The sliding surface gap can be adjusted easily from the outside with the adjusting unit whether the pump is operating or not, and the proper amount of leakage can be ensured.
The range comprises the following three types with bores from 15 to 250mm, total head from 10 to 90m and capacity from 0.001 to 8 tons/min: UENC type - Stainless steel cast construction with highly reputable degreasing and grease-proof treatment.
UEC type - Stainless steel construction, all lathed and electrolysis-polished.
UTC type - Stainless steel construction, all lathed and electrolysis-polished (High head, small capacity turbine pump type).
Yokota Manufacturing's clean pump technology also meets sanitary specifications.
The pumps are suitable for a wide range of applications including ultra-pure water production, liquid supply in clean rooms, food and beverage production, pharmaceutical production, and high purity chemical liquids processing.
