Bell & Gossett 1BL070 PL-130/3″ Pump 2/5 HP Motor

Large hydronic heating systems can use the Bell & Gossett 1BL070 PL-130/3-inch booster pump with 2/5 HP power, 115 V single-phase operation, cast-iron construction, a 3-inch flanged connection, and 150 psi maximum working pressure.

The low-head, high-flow classification makes this model a candidate for larger circulation networks where piping volume is substantial. The supplied record does not state exact flow, head, NPSH, temperature, seal details, or efficiency, so system resistance must guide final selection.

Key Features

- The 2/5 HP motor establishes the listed power class for hydronic equipment planning.
- 115 V single-phase operation supports electrical compatibility checks before installation.
- Cast-iron construction identifies the body material for closed-loop applications.
- A 3-inch flanged connection requires matching piping and companion-flange dimensions.
- The 150 psi maximum pressure sets the listed working boundary.
- Low-head, high-flow service narrows the model’s intended hydraulic application.
- Large-scale hydronic heating defines the documented system context.

Hydraulic Performance and Application

The PL-130/3-inch configuration is listed for large-scale hydronic heating and low-head, high-flow systems. Exact flow, head, NPSH, temperature, pump curve, and efficiency values are not supplied, so the 150 psi pressure rating cannot determine hydraulic suitability or a normal operating point.

Installation Requirements

Confirm 115 V single-phase power, 3-inch flange fitment, flow direction, rotation, fluid temperature, pressure below 150 psi, mounting orientation, and service clearance before commissioning. The cast-iron body is listed for closed loops, so open potable-water use requires a different documented material configuration.

Warranty and Maintenance

Bell & Gossett provides an 18-Month Limited Warranty from installation or a maximum of 3 years from the product date code, whichever occurs first, for Series PL boosters. Coverage addresses material and workmanship defects, while improper installation, misuse, alteration, negligence, and contrary operation are excluded. Mulmotor provides pre-purchase product guidance and order-related customer support.
