Bell & Gossett Series 60 B615S – Pump 3/4 HP 172775LF

Bell & Gossett 172775LF Series 60 Model B615S (Bronze, 1-1/2 HP)

The Bell & Gossett 172775LF is an ultra-high-flow Series 60 All-Bronze circulator pump designed for technical fluid management in institutional potable master boosters and large hospital DHW systems. Utilizing a massive 1-1/2 HP single-phase motor and 2″ flanged connections, this pump provides a professional solution for bulk sanitary water movement. By incorporating lead-free bronze construction and a maintenance-free design, this unit solves the problem of hydraulic insufficiency in high-occupancy buildings, ensuring a safe and stable circulating source with absolute mechanical reliability.

Technical durability in the B615S model is anchored by its 2″ x 2″ x 6-1/4″ configuration, which maximizes fluid turnover in primary potable loops. The all-bronze wet end remains impervious to the corrosive effects of oxygenated fresh water, preventing the rust-related friction common in ferrous pumps. It is a dependable choice for healthcare centers and large-scale commercial facilities requiring a high-output, certified lead-free pumping solution for centralized hot water distribution.
