Installing a Mechanical Seal in a Goulds 3196 Pump

Introduction

This tutorial provides a comprehensive guide on installing a mechanical seal in a Goulds 3196 pump, specifically focusing on cartridge seals. We'll discuss the differences between component and cartridge seals, the benefits of using cartridge seals, and best practices for de-assembling and installing the seal, drawing from the insights shared in the video by Gallagher Fluid Seals Inc.

Step 1: Understand Seal Types

• Component Seals vs Cartridge Seals

  • Component seals consist of separate parts that must be assembled during installation, which can increase the risk of errors.
  • Cartridge seals come pre-assembled and are easier to install, reducing the potential for installation mistakes.

• Benefits of Cartridge Seals

  • Simplified installation process.
  • Enhanced reliability due to fewer potential leak points.
  • Easier maintenance and replacement.

Step 2: De-assemble the Goulds 3196 Pump

• Gather Required Tools

  • Wrenches (appropriate sizes)
  • Screwdrivers
  • Pliers
  • Clean cloths

• Best Practices for De-assembling

  • Ensure the pump is turned off and properly isolated from the power source.
  • Drain any fluid from the pump to avoid spills.
  • Carefully remove the pump casing, noting the order of disassembly to aid reassembly.
  • Keep all parts organized and clean to prevent contamination.

Step 3: Inspect Components

• Check for Wear and Damage

  • Examine the pump shaft, housing, and other components for signs of wear or damage.
  • Replace any damaged parts to ensure a proper seal and pump operation.

• Clean the Area

  • Thoroughly clean the sealing surfaces to remove any debris or old sealant, which can affect the new seal's performance.

Step 4: Install the Cartridge Mechanical Seal

• Prepare the Cartridge Seal

  • Ensure the new seal (Cartex by EagleBurgmann) is compatible with your pump model.
  • Inspect the seal for any defects before installation.

• Installation Steps

  1. Lubricate the seal’s O-rings with a compatible lubricant.
  2. Align the seal with the pump shaft and carefully slide it into place.
  3. Ensure the seal is seated evenly without any gaps.

Step 5: Reassemble the Pump

• Follow Assembly Order

  • Reverse the order of disassembly to reassemble the pump.
  • Ensure all bolts are tightened to the manufacturer's specifications.

• Final Checks

  • Verify that the seal is properly aligned and seated.
  • Double-check for any tools or debris left in the pump.

Conclusion

In summary, installing a mechanical seal in a Goulds 3196 pump involves understanding the types of seals, careful de-assembly, thorough inspection, and proper installation of the cartridge seal. Following best practices throughout the process will enhance the reliability of your pump. For further maintenance, ensure that regular inspections are conducted to prolong the life of your mechanical seal and pump.
