BELL & GOSSETT
Frequently asked questions
Common questions about BELL & GOSSETT from 3G Electric.
What is the difference between the Bell & Gossett three-piece inline circulator pumps and the ECM circulating pumps?
Bell & Gossett three-piece inline circulator pumps, such as SKU 422W64 and SKU 788NP7, use a split-coupled design that allows the motor and impeller assembly to be serviced without disconnecting the pump body from the piping. They are available in bronze or cast iron and operate at fixed speeds. ECM circulating pumps, such as SKU 795F78, use electronically commutated motors with variable-speed operation, which can adjust flow to match system demand. ECM models are typically selected for hydronic heating systems where reduced energy consumption and precise flow control are required. Both types are available in flange or FNPT connections and operate on 115V AC or 115/208–230V AC.
What are the pressure and capacity ratings for Bell & Gossett thermostatic steam traps?
Bell & Gossett thermostatic steam traps are available in several pressure and capacity ranges. For example, the 17C-A-3-25 model is rated for a maximum operating pressure of 25 psi and a condensate capacity of 162 lb/hr. The 8C-A-3-125 model is rated for 125 psi maximum pressure and 4,200 lb/hr capacity. Both are angle-pattern traps with brass bodies and 3/4 in FNPT inlets. Selection depends on the steam system pressure and the volume of condensate to be discharged. These traps automatically discharge condensate and non-condensable gases while preventing steam loss.
What screen size and materials are used in Bell & Gossett brass Y strainers?
Bell & Gossett brass Y strainers, such as the 420C series, use a cast brass body and a stainless steel mesh screen with 0.0331 in openings. This screen size is suitable for capturing typical particulate debris in fluid lines. The strainers are available with 1/2 in, 3/4 in, and 1 in NPT connections. The Y-pattern design allows for inline installation and easy access to the screen for cleaning or replacement. These strainers are commonly installed upstream of pumps, valves, and heat exchangers to protect downstream equipment from fouling and wear.
Can Bell & Gossett circulator pumps be used in potable water systems?
Yes, certain Bell & Gossett circulator pumps are designed for potable water systems. Models with bronze volutes or bronze construction, such as SKU 422W64 and SKU 788NP7, are suitable for potable water because bronze resists corrosion and does not contaminate the water supply. These pumps are available with flange or FNPT connections and operate on 115/208–230V AC. When selecting a pump for potable water, verify that all wetted materials are compatible with the local water quality and that the pump meets any applicable plumbing codes. The three-piece design allows for service without breaking the potable water line.
What is the maximum flow and head for the Bell & Gossett ECM circulating pump SKU 795F78?
The Bell & Gossett ECM circulating pump SKU 795F78 (MPN 60B0B1000) delivers a maximum flow of 18 gpm and a maximum head of 20 ft. It operates on 115V AC and has a cast iron body with flange connections. The face-to-face dimension is 3 3/4 in. This variable-speed pump is designed for hydronic heating and general-purpose circulating applications where flow requirements vary. The ECM motor adjusts speed to maintain system performance, which can reduce power consumption compared to fixed-speed pumps. It is not intended for potable water systems due to the cast iron construction.
