    Expansion Tanks for Drinking Water

    These tanks meet NSF/ANSI Standard 61 for use with drinking (potable) water. Use them to accommodate the expansion of heated water and provide a cushion of compressed air in closed water-heating systems. All of these tanks have a diaphragm, which completely separates air and water. They prevent water loss by eliminating the need to expel hot water from systems during each heating cycle.

    Charge these accumulators to the pressure you need, and they will help a system maintain a constant pressure during pump failure. Mount accumulators within 25° of vertical. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
    Note: For safety, do not disassemble accumulators while they're under pressure.

    Expansion Tanks for Lubricants

    A rolling rubber diaphragm maintains tank pressure at or near 0 psi, which extends seal life to help keep lubricants clean. Use these tanks to accommodate the expansion of heated lubricants and provide a cushion of compressed air in closed lubricant-heating systems. They prevent lubricant loss by eliminating the need to expel hot lubricant from systems during each heating cycle.
