Date Added: 1st March 2011
The James Walker Group introduce the Chevron rod seals - a type of universal multi-lip packing which are well known for their exceptionally long service lives, their industry leading reliability and their capability to be used in a wide variety of mechanical devices, even in tough operating environments. These durable seals are made up of a gland ring combined with a female adapter, a header combined with a male adapter and at least one (and more depending on the specific model) V-rings in between the gland ring and header.
James Walker Chevron rod seals are tapered to provide initial interference once installed in the seal housing; this produces a radial force which along with the precise finish of the seal lip that ensures a secure seal even at low pressure. The seals are also usable in split form, in which case a scarf abutment is also used.
These seals are designed for use in tough operating conditions, making them ideal for applications where safety is critical. They continue to provide a secure seal in temperatures ranging from -20 to 100 degrees Celsius (seals above 250 millimeters in diameter can operate in temperatures of as high as 120 degrees Celsius or above) rod seals manufactured from special materials are available for applications involving temperatures of up to 260 degrees Celsuis, including hot oil or steam reciprocating pumps. They can stand up to operating pressures of as high as 42MPa, with even higher pressures possible using special materials and custom designed seals.
James Walker seals are suitable for use in the vast majority of mineral-based hydraulic systems and are resistant to water, air, grease and most oil-based lubricants. Custom versions are available which offer resistance to other media including fire-resistant liquids. Rod seals are available for use in both non-adjustable and adjustable housings.
