Hydraulic Seal - Heavy-duty Rubberized Fabric, Pressure Responsive Design With Asymmetrical Header Ring For Enhanced Sealing Integrity

we are the largest exporter, manufacturer and supplier of hydraulic seal in Mumbai, Maharashtra, India. this LofilmAR HD is a pressure responsive hydraulic seal specifically designed for arduous reciprocating gland applications, where fast pressure rises occur and side loads can be substantial. In heavy-duty horizontal applications, it operates as a highly efficient seal and also accommodates lateral or side loads.

The seal normally comprises one heavy-duty intermediate ring of rubberized fabric, a gland ring/female adapter, and a moulded rubber asymmetrical header ring that is the principal sealing element of the set.

An annular groove incorporated in the header increases its response to applied pressure. The ported 'odd-leg' header design allows gland loading to be transferred through the set to the neck bush - often not fixed - while enabling the system pressure to act on the annular groove. In addition, the rubber sealing lips conform readily to an uneven surface - such as a worn shaft - to improve sealing integrity.

In operation, the initial radial interference reduces the fluid film to a minimum over a wide range of conditions, particularly on down-stroking where excessive leakage can be hazardous. This is also important on equipment that uses auxiliary cylinders to provide rapid advance.
