Road line painting is a labour-intensive task that takes its toll on the marking equipment. One of the biggest maintenance issues is sealing of the internal pump caused by the aggressive nature of the paint. Constant breakdowns, repairs, and renewing of components lead to increased costs and a slowdown in this essential service rollout.

The key to overcoming this historical problem is to use a packing application that can withstand the constant onslaught of the solids in the paint moving within. Sealing experts Chesterton hasve created an innovative solution, known as DualPac technology, designed specifically to increase the lifespan of equipment subjected to such aggressive substances.

Extending pump longevity with an innovative mix of materials

The all-too-common scenario of packing failure can have a catastrophic effect on the equipment. Gland adjustments are a necessary evil for those tasked with maintaining line marking equipment to ensure sealing integrity.

However, even with such tweaks, the reality with traditional pump packing is premature wear and the associated lowered output and/or equipment damage this brings. Both PTFE (used at times for its “kindness” to equipment and chemical compatibility) and aramids (often used for its ability to withstand harsh conditions), the common components of packing, have their weaknesses (PTFE cannot handle abrasive media and aramids are “tough” on equipment).

The patented DualPac technology removes the need to choose between one or the other by utilising a unique combination to create a superior sealing capability.

Introducing Chesterton DualPac 2211

By combining graphite- filled ePTFE and resiliency aramid, the braiding technology provides an effective and long-lasting seal with a low level of friction. This is achieved with no compromise on shaft wear and dramatically increases longevity.

The unique formulation of DualPac uses the gland load in an ultra-efficient manner and achieves a shorter break-in period.

The result brings multiple advantages, including:

  • Reduced maintenance: Far fewer gland adjustments than is necessary when using traditional packaging
  • Improved sealing configuration: Thanks to a superior utilisation of gland load
  • Convenience: The packaging can be used for both sealing rings and end rings, thus reducing the need to purchase multiple different types of packing
  • Equipment longevity: The unique composition minimises shaft scoring and burnout
  • Economical: Achieves far greater periods between servicing as well as less overall maintenance
