ZU4/ZB4 series mechanical seals meet DIN24960 and GB6556 standards for centrifugal pumps and similar mechanical rotating shafts. The large CROSS-sectional surface of ZU4/ZB4 series mechanical seals can not only ensure the flatness of the end surface under high pressure, but also have good heat transfer ability, low and uniform temperature rise, strong resistance to thermal deformation. ZB4 refers to the balanced mechanical seal, as the name implies, ZB1 series of mechanical seals are generally used in high pressure conditions, can refer to pressure ≤4Mpa, applicable to all kinds of chemical fluids (excluding easy crystallization, solid containing more granular fluid). This series of mechanical seals have the simple structure of single spring seal and multi-spring seal as uniform end load and excellent dynamic performance, ZU4/ZB4 unique fork transmission structure, mechanical seals in use to obtain better transmission torque.
