Using a 20 HP ODP motor at 3550 RPM, the Bell & Gossett e-1510 1.5BC 20 HP ODP is a base-mounted end suction pump with a 175 psi standard volute rating. Its center member spacer coupling supports alignment and service-access planning. Large-building booster applications are the stated context for this 2.5-inch suction and 1.5-inch discharge configuration.

The high-speed motor and BC casing must be evaluated through the project pump curve, not by horsepower alone. The 175 psi figure is a maximum working-pressure limit for the standard volute. Confirm required flow, head, suction conditions, fluid properties, electrical supply, piping losses, coupling clearance, and documented application requirements before final selection or installation planning.

Key Specifications of the Bell & Gossett e-1510 1.5BC 20 HP ODP Pump

- The 1.5BC casing provides 2.5-inch suction and 1.5-inch discharge connections for matching building booster piping.
- A 20 HP motor establishes the listed drive capacity for the selected base-mounted end suction pump assembly.
- The 3550 RPM two-pole speed identifies the specified motor-speed reference for hydraulic and electrical selection.
- Open drip proof construction specifies the ODP motor enclosure for this high-speed e-1510 configuration.
- Standard volute working pressure is 175 psi, requiring comparison with project pressure requirements before installation.
- A center member spacer coupling provides the specified arrangement for alignment and service-access planning.
- Large-building booster applications are the stated context for evaluating this 1.5BC pump configuration.

Hydraulic Performance and Application

This Bell & Gossett end suction pump is listed for large-building booster applications using a 1.5BC casing. The 20 HP ODP motor, 3550 RPM speed, and 175 psi standard-volute rating do not define a system duty point. Use the applicable e-1510 curve to establish required flow, head, suction conditions, fluid properties, pipe losses, and discharge requirements before selection.

Installation and System Requirements

Confirm compatible three-phase power, motor rotation, approved system curve, operating pressure, and suction arrangement before installation. Verify that the 2.5-inch suction and 1.5-inch discharge connections fit project piping. Provide independent support to protect the casing from pipe strain. Reserve clearance around the spacer coupling for alignment and service, then follow official e-1510 procedures during mounting and startup.

Service and Maintenance Considerations

The center member spacer coupling requires access planning for alignment and service before adjacent pipework or equipment is installed. Follow official e-1510 lockout, coupling, alignment, and inspection procedures for the completed motor and pump assembly. Keep system pressure within the documented 175 psi standard-volute limit. Do not substitute rotating components without confirming the exact approved pump configuration.

Why Choose the Bell & Gossett e-1510 1.5BC 20 HP ODP

This assembly combines a 1.5BC base-mounted casing, 20 HP ODP motor, 3550 RPM speed, and 175 psi standard-volute rating. The center member spacer coupling adds a specific alignment and service-access consideration. Buyers evaluating large-building booster equipment can compare its 2.5-inch suction and 1.5-inch discharge connections with project piping, then validate duty through the e-1510 curve.

Warranty and Support

Bell & Gossett commercial pumps carry a 1-Year Limited Warranty against defects in materials and workmanship. Coverage starts at installation and ends no later than eighteen months from shipment, whichever occurs first. Seals, gaskets, elastomers, coatings, and other wear parts are excluded unless applicable sales documentation states otherwise. Mulmotor provides pre-purchase product guidance and order-related customer support.

Before Ordering the Bell & Gossett e-1510 1.5BC 20 HP ODP Pump

Before ordering, verify that your large-building booster project requires a 1.5BC casing with 2.5-inch suction and 1.5-inch discharge connections. You should select flow and head through the applicable e-1510 curve, then confirm the 20 HP ODP motor, 3550 RPM speed, and 175 psi pressure limit. Review suction conditions, pipe support, coupling access, fluid requirements, and installation clearance.
