Bell & Gossett 189105LF Bearing Assembly 2-1/2inch BI LD 3 HD 3 BI Comes with Seal Kit

Description

The Bell & Gossett 189105LF Bearing Assembly is a key component in various Bell & Gossett pump models, specifically for Series PR, 2-1/2″, LD-3, and HD-3 pumps. It plays a crucial role in ensuring the smooth and efficient operation of these pumps. Here’s a breakdown of its key features and functions:

Function:

• Supports the pump shaft: The bearing assembly houses and supports the pump shaft, allowing it to rotate smoothly and efficiently.
• Reduces friction and wear: The bearings within the assembly minimize friction between the shaft and the pump housing, preventing excessive wear and tear and extending the lifespan of the pump.
• Transfers power: The assembly efficiently transfers power from the motor to the pump impeller, creating the necessary force to move water.

Components:

• Bearings: Typically, the assembly includes two high-quality bearings, often ball bearings, designed for durability and smooth operation.
• Shaft sleeve: Some models may have a shaft sleeve that fits around the pump shaft and rotates within the bearings, further reducing friction and wear.
• Seal kit: The assembly usually includes a seal kit to prevent leaks around the shaft and ensure watertight operation.
• Gasket: A volute cover gasket is often included to create a watertight seal between the bearing assembly and the pump housing.

Benefits:

• Extends pump life: Replacing worn-out bearing assemblies with a new one prevents excessive wear on the shaft and other pump components, significantly extending the overall lifespan of the pump.
• Improves pump performance: Worn bearings can hinder pump efficiency and lead to reduced flow or pressure. Replacing the assembly restores optimal performance and ensures your pump operates at its best.
• Cost-effective repair: Compared to replacing the entire pump, a bearing assembly replacement is often a more cost-effective solution to address issues related to worn bearings.

Things to Consider:

• Compatibility: Ensure you choose the correct bearing assembly model (189105LF) compatible with your specific Bell & Gossett pump series, size, and model.
• Professional installation recommended: While technically feasible for DIYers with plumbing experience, installing a bearing assembly can be complex. Consulting a qualified plumber for installation is recommended, especially for critical plumbing systems.
