Zero Leaks: Technical Services


Protec Arisawa has you covered with all the replacement parts, field service support and operator training to ensure your system is operating leak-free and safely. 

The membrane housing is meant to be a closed system and all water should be contained within and all leaks stopped as soon as possible. The outside of the vessel, especially the head area, is not designed to be wet and no sitting water should be present. Protec can help you identify the cause of vessel leaks, get the proper replacement parts and provide our expert team to fix them. 

Protect your asset! No leaks or external water should be tolerated on your system. Subject to operational uptime, seals have an average life of 3-5 years and should be inspected and changed regularly. High and low pH exposure can decrease the life of a seal and the frequency for change will vary depending on how the system is operated and cleaned. 

Enough seals for at least 10% of the vessels should be kept in stock at an operating facility and changed regularly. It is important for every operating plant to keep a safe level of shelf spares on site for emergency and routine maintenance. Permeate ports, thrust cones, membrane adapters and shims are common items that should be on hand.

  • Have you checked your seals lately?


  • Did you know vessel leaking and external water can damage your vessel?

  • What spare parts do you have in stock?


  • Want to know how to prolong the life of your vessel and safely operate the membrane housing?


Protec Arisawa’s field service team provides operator training and general maintenance guidelines to ensure seals are secure and the vessel integrity has not been compromised. Our highly experienced field service engineers and technicians will efficiently and expertly disassemble, clean, inspect, and replace all the parts of the pressure vessel to ensure seals are securely placed and the vessel’s integrity has not been compromised. Fixing leaks and keeping vessel heads dry will ensure the safe operation of the system and prolong the life of the vessel. Should you need assistance in troubleshooting pressure vessel leaks, please contact Protec Arisawa or your Original Equipment Manufacturer (OEM). 

Protec Arisawa keeps a large inventory of spare parts at our factory in Vista – CA, for immediate delivery to OEMs and End-users.  All vessel parts should be kept clean and free of debris and corrosion. All internal and external vessel parts should be regularly inspected for possible cracks or wear.  Contact your authorized Protec Arisawa representative or account manager today for part numbers and pricing. 

Contact Protec Arisawa, or your system OEM, for parts pricing, trouble-shooting and field service assistance to get your plant leak free and ensure you have a safety stock of all vessel parts.
