Bell & Gossett 1BL017LF PL-50B Pump with 1/6 HP Motor

Radiant-floor heating and domestic-hot-water systems can consider the Bell & Gossett 1BL017LF PL-50B with 1/6 HP, 115 V single-phase power, lead-free bronze construction, sleeve bearings, and a high-head circulator configuration.

The Bismaleimide non-metallic impeller and sleeve-bearing design provide component references for application and service review. The listed application covers DHW systems and radiant-floor heating, while exact flow, head, temperature, pressure, pump curve, and efficiency values are not provided in the supplied record.

Product Features

- The 1/6 HP motor establishes the listed power class for electrical planning and system comparison.
- 115 V single-phase operation supports compatibility checks for standard hydronic electrical supplies.
- Lead-free bronze construction provides the documented body material for domestic-water evaluation.
- Sleeve bearings identify the internal support arrangement for service and replacement planning.
- A Bismaleimide non-metallic impeller provides the listed material reference for component review.
- The high-head model designation narrows application screening but does not establish a numerical head rating.
- DHW systems and radiant-floor heating are the documented application contexts for evaluation.

Performance and Application

The PL-50B is listed for high-performance domestic-hot-water systems and radiant-floor heating. The supplied record does not state exact flow, head, NPSH, pressure, temperature, pump curve, or efficiency values, so the high-head designation cannot replace duty-point verification for the intended piping system.

Installation Requirements

Confirm 115 V single-phase power, piping and flange compatibility, flow direction, rotation, sleeve-bearing service access, fluid temperature, and application fluid suitability before installation. The lead-free bronze body supports material review, but the available information does not independently establish every potable-water certification requirement.

Warranty and Support

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 defects in materials and workmanship, while improper installation, misuse, alteration, negligence, and contrary operation are excluded. Mulmotor provides product-information support before purchase and assistance with order-related questions.
