3. Installation

Safety First:

  • Always disconnect power to the pump before beginning any installation or maintenance.
  • Ensure the pump system is depressurized and drained to prevent injury from hot water or high pressure.
  • Wear appropriate personal protective equipment (PPE), such as gloves and eye protection.

The following steps outline a general procedure for installing the seal kit. Specific pump models may require additional steps or specialized tools. Refer to your pump's specific service manual for detailed instructions.

  1. Prepare the Pump: Isolate the pump from the system by closing isolation valves. Drain the pump casing completely.
  2. Disassemble the Pump: Carefully remove the pump casing bolts and separate the casing from the motor assembly. Note the orientation of all components for reassembly.
  3. Remove Old Seals: Locate and carefully remove the old gaskets and seals. Inspect the sealing surfaces for any damage, corrosion, or debris. Clean these surfaces thoroughly.
  4. Select Correct Gaskets: Identify the correct size gaskets from the kit that match the original seals and the pump's specifications. The kit includes various O.D. sizes (7", 8", 9-1/2", 10", 12", 14").
  5. Install New Gaskets: Carefully place the new gaskets onto the clean sealing surfaces. Ensure they are seated correctly and not twisted or pinched.
  6. Reassemble the Pump: Reassemble the pump casing to the motor assembly, ensuring all bolts are tightened evenly and to the manufacturer's specified torque settings.
  7. Test the System: Slowly refill the pump system, checking for any leaks. Once filled, restore power and carefully monitor the pump's operation for any unusual noises or signs of leakage.

4. Maintenance

Regular inspection and timely replacement of pump seals are crucial for preventing system downtime and costly repairs. While the seal kit itself is a replacement part, its proper function relies on ongoing maintenance practices.

  • Routine Inspection: Periodically inspect the pump for any signs of leakage around the casing or shaft. Even minor drips can indicate a failing seal.
  • Performance Monitoring: Monitor pump performance. A decrease in efficiency or unusual noise could be a symptom of seal degradation.
  • Replacement Schedule: Follow the pump manufacturer's recommended seal replacement schedule. If no schedule is provided, consider replacing seals during major pump overhauls or if signs of wear are observed.
  • Storage: Store spare seal kits in a cool, dry place away from direct sunlight and chemicals to preserve their material integrity.

5. Troubleshooting

If you experience issues after installing the seal kit, consider the following common problems and solutions:

Problem Possible Cause Solution
Leakage from pump casing
  • Incorrect gasket size used.
  • Gasket pinched or improperly seated during installation.
  • Sealing surfaces not clean.
  • Casing bolts not tightened evenly or to correct torque.
  • Verify correct gasket selection.
  • Re-open casing, inspect gasket, and reinstall carefully.
  • Clean all sealing surfaces thoroughly.
  • Retighten casing bolts evenly to specified torque.
Reduced pump performance / Air ingress
  • Gasket not sealing properly, allowing air into the pump.
  • Damage to the gasket during installation.
  • Inspect gaskets for damage or improper seating. Replace if necessary.
  • Ensure all connections are tight.

If troubleshooting steps do not resolve the issue, contact a qualified technician or the manufacturer for assistance.
