Piston Cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Homogeneous Piston Cups are typically used in low pressure applications (under 150 PSI) for service in pneumatic, hydraulic fluids, & water. Fabric reinforced Piston Cups are commonly used in applications with pressures reaching up to 1000 PSI or in applications where a larger extrusion gaps are present. SPT Seals also produced a line of double acting piston cups (PCD Piston Cups) that replace multi-part assemblies. Homogeneous rubber is bonded to a metal disc, only one part is required - the most practical piston cup available. These are designed for pneumatic or low pressure hydraulic applications.
The piston is made of a highly durable heat-resistant fabric that is used to make body armor. pistons are the best in the market for durability (over 1300 hours of operation it depends on the conditions of use).
What are pistons suitable for? Work in aggressive environments where abrasive and corrosive liquids prevail.
Where is used. pistons are preferred by companies that operate in drilling because they use bentonite-based fluids and polymers.
Pistons are available in many sizes like 2.25″ 2.5″, 2.75″, 3″ and we can make many more size as per requirement.
