Machinery & Chemical Pumps
Endures continuous impulse pressure up to 700 bar with zero durometer degradation in petroleum and synthetic water-glycol fluids.
Precision EPDM and FKM seals resisting synthetic motor oils, extreme thermal shock from -40°C to +220°C, and engine vibration.
High-tensile rubber rings resisting abrasive slurry exposure, concentrated acids, and continuous multi-shift duty cycles without swelling.
Validated under severe dynamic stress
Every compound formulation undergoes batch-level tensile, elongation, and compression set testing in accordance with ISO 37 and DIN 53504 standards. Our material laboratory verifies seal resilience against fluid swell under high pressures.
With full compound traceability back to raw batch compounding, mechanical engineers specify Apex PolySeal rings for critical industrial equipment where unplanned seal failure causes catastrophic operational downtime.
