Armstrong - HSC Fire Pumps & Packaged Systems

The Series 4600F, drawing on over 100 years of pump design expertise and leadership, is the state of the art in Horizontal Split Case pumps. It meets or exceeds the requirements of nfpa and testing laboratories involved in fire protection such as ul, ulc & fm. The family of pumps capitalize on the "Tilted Parting" concept to minimize turbulence at the eye of the impeller by its straight laminar approach, thus maximizing efficiency.

The family was designed with commonality of parts, low installation cost, and ease of maintenance objectives.The pumps' compact sizes are ideally suited for space saving packages and retrofit applications.

• PTFE & Graphite bonded together in a single molecular structure
• Dense pliable packing with a high degree of resiliency
• Does not cause shaft wear
• Dissipates heat without chemical hardening, resistant to chemicals
• Resistant to most chemicals.
• Outlasts the service life of most other similar packings.
