Since 1915, NASH Engineering pioneered original designs of vacuum heating pumps, becoming the premium supplier.  Today we offer replacement kits and components to upgrade and renew these steam heating units. They include pumps and motors built with current technology, yet they can be used with all the old NASH vacuum heating pump units.  A NASH replacement kit can save you thousands when compared to a complete new pump unit. In addition, you'll get higher air capacity, increased fuel efficiency, and equipment that's much easier to maintain and service. Your heating system will again respond to all of its controls the way it was designed.  Drawings and instructions furnished with the replacement kits.
