HDD series features
The D series is a precision cast shell D-shaped sleeve structurewith smooth shaft sleeve lubrication and cooling design inside.This structure is suitable for highly viscous fluids and can bepumped under high vacuum conditions. The measurement accu-racy can reach 1 %o, and it is designed with various corrosion-re-sistant materials.
