LPS-151, LPS-151-R & LPS-155-S

LPS-151, LPS-151-R & LPS-155-S series are specially designed PTFE (Teflon) bellow Mechanical Seals for light & extremely corrosive chemicals including concentrated acids, salts, strong oxidising, reducing agents and chemically active organic compounds. These seals are independent of direction of rotation, these seals are externally mounted with easy installation procedure, these seals can be offered in composite & replaceable faces version. All the components which come in contact with media to be sealed are made of chemically inert materials, metallic components, clamp ring and springs are located outside of the pump’s stuffing box so does not come in direct contact of fluid, these seals are comfortable to use in wide range of application as below:
