Pump expansion vessels


Many of today’s water systems require backflow prevention. This seals off the system and requires the use of an expansion tank, or the relief valve can discharge on every heating cycle. TW Series tanks eliminate wasting water and provide a smooth operating system, and assure long trouble-free service.

Our pump tanks are designed for installation flexibility and years of trouble-free service. Smooth, dependable diaphragm design and operation provides precise control of system operation cyles. Free-standing and in-line vertical tanks are available, as well as horizontal tanks with universal pump mounting bracket.
