High reliability! Utilizing the controlled rotational energy of the pump shaft.
The "TYPE 28VL" is a dry gas seal that utilizes spiral groove technology with a proven track record. It utilizes the controlled rotational energy of the pump shaft to vaporize the process fluid, creating a stable gas film that lubricates the sealing surface. Typical issues such as dry running wear, vapor lock in the seal chamber, and "face pumping" are eliminated by the non-contact technology of this product. 【Features】 ■ Long lifespan ■ High reliability ■ Reduced power consumption ■ Zero process contamination ■ Reduced emissions *For more details, please refer to the PDF materials or feel free to contact us.
