Single end, balanced, independent direction of rotation, rubber bellow transmission. Compact structure with good compatibility and easy installation. The bellow and spring provide pressure compensation to the sealing faces. The rubber bellow design prevents radial runout so the floatability of the rotary ring is increased. Can work as an alternative to similar John Crane products. Widely used in centrifugal pumps, vacuum pumps, submerged motors, compressors, agitation equipment and decelerators for sewage treatment, chemical engineering, pharmacy, paper making and food processing.

WB2 (Type 152) PTFE Bellow Mechanical Seal for Acid Proof Pumps, Plastic Pumps, Alkali Pumps, and Vacuum Equipment. Single end, balanced, independent direction of rotation, PTFE bellow, external type mechanical seal. Easy to install with pressure compensation to sealing faces. The bellow design prevents radial runout so the floatability of the rotary ring is increased. Widely used in acid proof pumps, plastic pumps, alkali pumps, vacuum equipment and other rotary devices.

Type 169 Multiple Spring PTFE Elastomer Bellow Mechanical Seal for Chemical Pumps. Single end, multiple springs, balanced PTFE elastomer bellow. Uses multiple small springs and PTFE bellows as compensation components. Rotary component driven by PTFE bellow. Outboard installed. Widely used in chemical pumps, especially alkali pumps that work with alkali liquid containing solid particles.

301 (BTAR) Mechanical Seal for Piping Pumps and Clean Water Pumps. Single end, unbalanced, independent direction of rotation, rubber bellow transmission. Compact structure, easy to install. The bellow and spring provide pressure compensation to the seal faces. The rubber bellow design prevents radial runout so the floatability of the rotary ring is increased. Can work as an alternative to Burgmann BTAR. Widely used in clean water pumps, piping pumps, submerged agitators, temperature control pumps for sewage treatment, food processing, water supply, and other civilian usages.

JBMFO, AKA MFL85N or 680 and 680M Metal Bellow Mechanical Seal. Single end, balanced, independent direction of rotation, bellow transmission.
