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.
The engines included in the selection tables are listed by UL, ULC and FM satisfactory for driving any pump with a maximum BHP requirements not exceeding the listed and/or approved ratings at sea level.
