LEP, supported by Quadrant Plastics, has been a solution provider for the energy generation industry for many years.
Our expertise is built on application successes in traditional energy sectors like oil & gas, but more and more in emerging alternative energy fields such as wind and solar.
Our materials are extensively tested and able to operate under harsh chemical and even extreme thermal conditions.
Our high performance materials offer the advantages of all plastics, helping to reduce weight and allow for the substitution of other materials like steel, aluminium or ceramics, due to their high specific strength.
Solar: Our materials have been tested and certified for applications in vacuum chambers offering very low out gassing. We also offer materials for wet process environments presenting low out leach values.

The objective for the Hydro Power Station was to replace a metal crown seal with an abrasive resistant plastic seal for increased wear in a high pressure environment, as well as reduced downtime through less-frequent replacement. The plastics seals are also lighter and easier to install.
Produced for Hydro Power Station, these bearings are used on the periphery of the swing ring which actuates wicket gates, controlling water flow into turbines in hydro power station. While turbine speed is constant, for more power the induced current is increased resulting in greater torque on the bearing. These are low/slow speed bearings chosen for zero stick slip.
Large (300mm) end plates for pumps to handle dirty water conditions. Polyurethane has been used for it’s wear resistance capabilities with aggressive materials.
Manufactured for SHUK Engineering Distributors Ltd, New Zealand’s largest manufacturer and distributor of sealing products.
LEP manufactures a wide range of industry standard PTFE RTJ seals for pipework.
