M74R-D

M74R-D Double End Mechanical Seals for Chemical Centrifugal Pumps, KSB/Kaiquan Water Pumps and Double Suction Pumps, Design Improved from Traditional M74-D Seals

Structural Features: double end, small spring, unbalanced, independent direction of rotation, drive sleeve transmission, back to back design. This component can work as an alternative to similar original seal components of KSB and Kaiquan water pumps. M74R-D is a improved version of M74-D, designed by YALAN Seals. The transmission lug on the rotary part was changed from shape edges into rounded edges so it reduces the chances of damaging the rotary seal ring.

Industrial Standards: DIN24960, ISO3069, and GB6556

Scopes of Application: mainly used in chemical centrifugal pumps, vacuum pumps, axially split pumps, blowers, compressors and paper-making equipment for chemical processing, oil refining, petrochemical engineering, sewage treatment, pesticide and chemical fertilizer production.
