Single Spring Unbalanced/Balaced Mechanical Seals ( Clutch Type )

LPS-041-U/LPS-045-U & LPS-051-B/LPS-055-B

LPS-041-U/LPS-045-U & LPS-051-B/LPS-055-B series are internal mounted single helical coil spring bi-directional unbalanced/balanced Mechanical Seal designed for dirty media & clogging type applications. It is independent of direction of rotation, these seals are driven by drive ring or drive collar with clutch type arrangement, in case if spring clogged but rotary will be driven reliably, seals are having easy fitment & pushed with drive ring or drive collar support, double “V” packing are spring energized to give perfect dynamic sealing. As all parts are interchangeable, one can convert this series LPS-041-U/ LPS-051-B  to LPS-045-U/LPS-055-B by changing only the dynamic ring and the secondary seal, this principle is ideal for stock rationalization, this seal are comfortable to use in wide range of application as below:
