Bell & Gossett 3EB e-1510 7.5 HP 3 Phase ODP Pump

Description

Primary HVAC chiller loops can use the Bell & Gossett 3EB Series e-1510 with 7.5 HP power, 1,750 RPM operation, ODP motor construction, 5-inch suction, and 4-inch discharge connections. The base-mounted layout suits bulk-fluid transfer, while the flexible center-member coupling requires proper alignment during installation.

The 3EB case provides a defined piping and equipment-room reference for larger circulation systems. Its 7.5 HP motor identifies the electrical load class, but it does not confirm the required flow, head, NPSH, or efficiency. Final selection should follow the pump curve and the actual chiller-loop duty.

Technical Specifications

• The 7.5 HP motor establishes the listed power class for chiller-loop electrical planning.
• Operating at 1,750 RPM provides the speed reference for curve and motor coordination.
• ODP construction requires suitable indoor environmental conditions for motor placement.
• Five-inch suction and 4-inch discharge connections define the primary piping references.
• The 3EB case identifies the pump size for dimensional replacement review.
• A flexible elastomeric center-member coupling requires alignment and service-clearance planning.
• Bulk-fluid transfer and primary HVAC chiller loops define the listed applications.

Hydraulic Performance and Application

Bulk-fluid transfer and primary HVAC chiller-loop service are the documented applications for this pump. Exact flow, head, NPSH, pressure, temperature, curve, and efficiency values are not supplied, so the 7.5 HP rating and 1,750 RPM speed cannot establish the operating point.

Installation Requirements

Confirm 5-inch suction and 4-inch discharge piping, ODP motor conditions, three-phase electrical requirements, foundation support, coupling alignment, rotation, service clearance, and seal access before commissioning. The base-mounted arrangement should remain accessible for inspection and future coupling or pump service.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from shipment or a 1-Year Limited Warranty from installation, whichever occurs first, covering defects in materials and workmanship. Improper installation, misuse, alteration, negligence, and contrary operation are excluded. Coupling alignment and mechanical-seal condition remain important service checks. Mulmotor provides product-information support before purchase.
