Bell & Gossett has long been known to produce some of the finest pumps in the Hydronics world. Three pumps that are commonly used in hydronic installations are the e-1510, e-1531, and the e-1532. All three pumps are end-suction pumps but with their own advantages, specifications and capabilities.
e-1510 Pump Features
All three pumps have what is known as an expanded “efficiency island”, this refers to the ability to provide for efficient pumping across a wide range of operational conditions, reduce energy consumption, and improve overall system performance.
True Back Pullout
A B&G standard in design and construction. Ease in service is assured, while piping and motor remain undisturbed. Extended delays for repairs are virtually eliminated.
Solid-Foot Mounted Volute
All Series e-1510 pumps are provided as standard with an integrally cast volute foot located directly beneath the pump volute. This integrally cast foot ensures that the alignment between the volute and motor assembly is maintained. Without solid support beneath the volute, the piping weight alone will cause distortion which can lead to premature failure of the bearings, shaft and mechanical seal. This feature is equally important on hot water applications. The Series e-1510 volute foot provides a solid foundation and eliminates the deflections which would otherwise exist within an unsupported overhung volute during the normal thermal expansion of the system piping against the volute.
Center Drop-Out Spacer Coupling
Unlike conventional jaw type or rigid style couplings, a center drop-out spacer coupling allows removal of the bearing frame and rotating element without disturbing the pump end pipe alignment or motor electrical connections.
Stainless Steel Impellers
The e-1510’s optimized hydraulic designs offer large efficiency “islands” maximizing operating efficiency over wide ranges of performance. e-1510 impellers are precision cast stainless steel providing extremely smooth surface finishes and tight dimensional tolerances to further yield higher efficiencies. Stainless steel impellers are also more resilient than bronze impellers, providing owners with longer lasting maximum efficiency levels and applications over a wider range of fluids.
Internally Self-Flushing Mechanical Seal
This design is way ahead of its time. This unique seal design is proven in many years of service. It requires no special external flushing provisions, since the design provides for constant efficient flushing action internally. This standard feature ensures maximum seal face lubrication, heat dissipation and debris removal without vulnerable, external flush tubing. The internal flushing action passes two and a half to three times the flow over the seal faces — compared to a few GPM for conventional, stuffing-box designed pumps.
OSHA-Compliant Coupling Guard
The coupler guard complies with OSHA 1910.219. The guard offers increased protection against potential injuries and is standard on all e-1510 pumps. The guards include slotted viewing windows for easy inspection.
Heavy Duty, Rugged Baseplate
The Bell & Gossett fabricated heavy duty baseplate is supplied as standard on every Series e-1510 pump. Unlike rolled steel and “C” channel baseplates, the Series e-1510 baseplate provides a heavy duty saddle assembly, full seam welds, closed baseplate ends and an open top to provide ease of access for proper equipment grouting.
Bell & Gossett Centrifugal Pumps Line
Bell & Gossett’s complete line of in-line and base-mounted centrifugal pumps can handle virtually any HVAC and plumbing requirement. The pumps are engineered for exceptional performance and rugged durability. They are designed for easy maintenance and to be highly efficient. The pumps provide reliable operation in a variety of applications, including hydronic heating and cooling systems, industrial, refrigeration, cooling towers and irrigation. All B&G pumps are manufactured at an ISO 9001- approved facility.
The Series e-1510 base mounted end suction pumps deliver the highest efficiencies, performance and durability. All pumps feature stainless steel impellers with an extensive efficiency profile that enables users to maintain significantly higher levels of efficiency over a much wider range of operating conditions. The Series e-1510’s dramatic improvement in efficiency is the result of cutting edge computational fluid dynamics (CFD) design technology, deep hydraulic engineering expertise, and Xylem’s comprehensive knowledge of HVAC and plumbing applications. The Bell & Gossett Series e-1510 is available in 26 sizes and a variety of configuration options that enables customization and flexibility to fit a broad range of operating condition
All B&G Series-1510 Pumps are available with TECHNOLOGIC Intelligent Pump Controllers and Variable Speed Drives. The e-1510 also features true back pullout – True Back Pullout A B&G standard in design and construction. Ease in service is assured, while piping and motor remain undisturbed. Extended delays for repairs are virtually eliminated.
This pump is also End-suction, close-coupled pump available in 1-1/4” through 6” sizes. Motor size 3/4 to 50 HP at 1750 RPM, 2 to 60 HP at 3500 RPM. Available with stainless steel shaft sleeve and impeller as standard with flows to 2300 GPM, heads to 400 feet. Close-coupled, space-saving economy plus rugged construction make the Series e-153 1 an ideal selection for a variety of horizontal and vertical mount (with impeller modification) applications. Available with the Bell & Gossett standard self-flushing Carbon/ Ceramic mechanical seal in 175# working pressure design.
End suction, close-coupled, foot-mounted pump available in 1-1/4” through 8” sizes. Motor size 3/4 to 50 HP at 3500 RPM. Available with stainless steel shaft sleeve and Impeller as standard, with flows to 2500 GPM, heads to 400 feet. Space-saving economy and back pull-out design, plus a rugged construction make the Series e-1532 an ideal choice when footed volutes are required. Available with the Bell & Gossett standard self-flushing Carbon/ Ceramic mechanical seal in 175# working pressure design.
