PolyGobal’s sealing solutions are industry recognised from over 30 years of engineering excellence and expertise.
PolyGlobal’s seals are an essential industry solution protecting integral machinery and equipment across the world’s most critical sectors. Offering a range of profiles and sealing specifications including energised, twinset and cup seals, products for rod & piston applications and a selection of wiper options, PolyGlobal’s specialist engineering division provides bespoke and standard seals from new and existing designs.
Our materials have excellent wear and abrasion resistance due to their outstanding mechanical properties. They also exhibit oil, chemical and hydraulic resistance to meet the demands of their working environments. The quality of these components is paramount to ensure that the reliability and lifespan of the products and technologies they are used in is maximised, downtime is minimised and performance is improved.
PolyGlobal’s rod seals work to seal along the cylinder. They maintain system pressure on the rod side, and prevent fluid leaking from within the cylinder as the rod reciprocates past it. Often these are the most important aspect of a sealing system, as failing seals lead to failures in performance rather than just inefficiency.
PolyGobal’s piston seals are utilised in both pneumatic and hydraulic applications to ensure system pressure is maintained along one side of the piston. Effective piston seals successfully facilitate the application of maximised mechanical effort in the movement of the piston along the cylinder and optimise performance. Piston seals ensure efficient performance.
Generally utilised in more traditional machinery and applications, PolyGlobal’s cup seals have a similar application to piston seals. As the piston moves along the cylinder, the cup seal prevents leakage and ensures pressure is maintain on one side if the piston. Whilst this application is similar, the seal profile and design is significantly different to suit the head of the ram.
From profile development to seal production, PolyGlobal offers advanced capabilities for specialist sealing solutions such as bellows and pipe seals. These sealing solutions lend themselves to a diverse range of applications. Due to the variety and profile design of bellows, for example, they are effective solutions in rotational applications which require durable protection from debris and dust, such as a car’s CV joint.
Standard sealing solutions can be adapted, combined and modified to produce a range of enhanced seals that provide solutions for additional applications and environments. Vee packs (or chevron seals) and twinsets are combination seals which incorporate a firm splitting seal with a standard grade, which changes the performance of the seal under pressure.
Wipers or scrapers are an integral part of the sealing system. Their role is to ensure the cylinder chamber remains free of contaminants such as moisture, dust and debris. The presence of these contaminants can result in damage to the other parts of the sealing system or to the rod itself. This sealing solution works to ensure efficient performance.
