Petrochemicals & Refinery

Petrochemicals and refineries are a major field of application for Escodisc couplings as their use drastically reduces customers’ operational costs. For reliable production, it is essential that production processes run smoothly and for an extended period of time. Escodisc couplings are completely machined with an inherently high degree of balance and are ideally suited to drive rotating equipment such as pumps and compressors smoothly as Escodisc couplings’ main unique features are maintenance free and designed for "infinite life". Industrial customers from the petrochemical and refinery sector worldwide have been relying on our Escodisc couplings for decades as an approved product, taking advantage of its features to lower the rotating equipment’s Life Cycle Costs.

ESCO Couplings Escodisc couplings are, depending on requirements, supplied to comply with industrial standards as i.e. API 610, API 671, Atex requirements and DIN norms such as DIN 740, etc.


The petrochemical and refinery industry operate constantly 7/24/365 and thus, the reliability of the equipment is of the greatest importance. A major concern is the cost of maintenance, hence the specific requirements.

Beside its classic Escogear couplings, ESCO Couplings has developed its high-performing Escodisc couplings responding successfully to the demand for infinite life formulated by this industry.

Escodisc couplings are for example driving pumps, mixers and compressors reduce maintenance costs to almost zero.
