Is the Rubber bellows for 115 EPDM compensator suitable for use with seawater and glycol at temperatures up to +90Â°C?

Yes. Rubber bellows for 115 EPDM compensator is suitable for use with seawater and glycol at temperatures up to +90Â°C. The product description explicitly lists seawater and glycol among compatible media and specifies an operating temperature range up to +90Â°C (depending on the medium). Inner and outer layers of EPDM rubber are chemically compatible with water-based fluids and glycol, and the construction includes nylon reinforcement and BV certification. It is not suitable for media containing oil.

Can Rubber bellows for 115 EPDM compensator be used with weak acids, bases, esters or ketones within the -30Â°C to +90Â°C range?

Yes. Rubber bellows for 115 EPDM compensator can be used with weak acids, weak bases, esters and ketones within the -30Â°C to +90Â°C range. The product description explicitly lists those media (hot and cold water, treated/industrial/seawater, glycol, weak acids, bases, esters and ketones), has an EPDM inner and outer layer and nylon reinforcement, and notes the operating temperature range (â30Â°C to +90Â°C, depending on the medium). Not suitable for media containing oil. BV certified.

Does the Rubber bellows for 115 EPDM compensator require special maintenance when used with treated or industrial water?

Rubber bellows for 115 EPDM compensator do not generally require special maintenance solely because they are used with treated or industrial water, provided the water chemistry falls within the materialsâ compatibility range and operating temperature (-30Â°C to +90Â°C). EPDM inner and outer layers are resistant to hot and cold water, water with treatment additives, industrial water and weak acids/bases. However, to ensure reliable long-term performance follow these precautions: - Periodic inspection: check for surface cracks, swelling, hardening, abrasion or delamination of the EPDM layers and for damage to the nylon reinforcement. Inspect joints, flanges and fastenings for leaks or corrosion. - Monitor water chemistry: avoid exposure to oils, strong acids, strong alkalis, aggressive solvents or substances known to attack EPDM; if water treatment includes such chemicals, verify compatibility. - Temperature and pressure limits: ensure operating conditions remain within the specified temperature and pressure ratings for the compensator. - Cleanliness: remove deposited solids, scale or aggressive deposits that could abrade or locally attack the rubber. - Replace on degradation: if any signs of significant aging, mechanical damage or loss of elasticity appear, replace the bellows rather than attempt repairs in service. - Certification and documentation: keep installation and maintenance records in line with BV certification requirements and any local standards. In short: no special maintenance beyond standard inspection, monitoring of water chemistry and adherence to temperature/pressure limits is required, unless the treated or industrial water contains substances incompatible with EPDM (e.g., oils or strong solvents), in which case additional measures or alternative materials are needed.
