HSC FIRE PUMPS & PACKAGED Systems

Horizontal split case
HSC fire pumps

Armstrong Holden Brooke Pullen takes you back to the future with the Series
4600 Horizontal Split Case (HSC) Pump for HVAC and industrial applications.

Introduction
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, and FM.
The family of pumps capitalise on the “Tilted Parting” concept to minimize turbulence at the eye of the impeller by its straight laminar approach, thus maximizing efficiency.
This also results in the lowest profile and minimum floor space of any HSC pump on the market today. 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.
With years of experience in package assembly for the fire protection industry, Armstrong can supply fire pump systems with all necessary accessories assembled and ready for site installation.

GUARANTEED ADVANTAGES
• Installation time reduced
• Simplifies piping design
• Single source unit responsibility
• A complete package that will meet NFPA-20 requirements
