The  ikiqat emişli split qutu nasosu  is a critical component in large-scale water transport systems, industrial cooling, HVAC systems, and municipal water supply. Its efficient and balanced hydraulic design offers high flow rates and stable performance. However, to ensure reliable long-term operation, routine maintenance is essential. Proper maintenance not only minimizes unexpected downtime but also extends the lifespan of the pump. This guide outlines essential maintenance tips for double suction bölünmüş halda pumps, helping users to avoid common mistakes and perform professional-level inspections and repairs.

1. Understand the Pump Before Maintenance

Before attempting any repairs or disassembly, thoroughly review the instruction manual and engineering drawings of the pump. Understanding the structure, function, and working principle of the double suction split case pump is crucial to avoid errors. Avoid blind disassembly—take detailed photos and make reference marks during the dismantling process to ensure easy and accurate reassembly later.

2. Safety First: Preparation Steps

Prior to maintenance, ensure that all safety procedures are followed:

Disconnect and lock out the power supply to the motor.

Confirm that the inlet and outlet valves are fully closed.

Drain the remaining water from the pump casing and pipeline.

Use appropriate grounding methods and display maintenance signage to alert others.

Prepare necessary tools and protective equipment.

3. Dismantling the Pump Properly

Follow the correct procedure to dismantle the double suction split case pump:

Remove the motor, coupling bolts, packing gland bolts, and the center-opening bolts.

Disassemble the bearing end covers and top cover.

Carefully lift the pump cover and rotor to expose internal components.

Take care to avoid damaging mating surfaces, shafts, and seals during removal. Store parts in clean, organized locations.

4. Conduct a Thorough Inspection

Inspect all components of the double suction split case pump, including:

Pump casing and base: Check for cracks, corrosion, and signs of cavitation.

Pump shaft and sleeves: These should be free of corrosion, cracks, or heavy wear. Replace if worn beyond tolerance.

Impeller and internal flow channels: Must be clean, corrosion-free, and without blockages. Pay close attention to blade condition.

Bearings: Rolling bearings should rotate smoothly without noise. Check for rust, pitting, or other damage. Sliding bearing oil rings should be intact, with no cracks or metal flaking.

Seals and gaskets: Inspect for wear, deformation, or hardening. Replace as needed to ensure leak-proof operation.

5. Reassembly Guidelines

Once maintenance and part replacement are complete, proceed with reassembly:

Reassemble components in reverse order of disassembly.

Avoid impacting parts directly—use appropriate tools and techniques.

Ensure the impeller is accurately centered and the axial position of the shaft is correct.

Bearings should be installed without hammering and should rotate freely without obstruction.

Perform a turning test to verify the rotor moves freely, and confirm axial movement is within allowable limits.

6. Post-Maintenance Testing and Documentation

After reassembly:

Perform a dry run before reintroducing fluid to ensure there is no binding or abnormal noise.

Slowly fill the pump casing with liquid, bleed air from the system, and monitor the seal area for leaks.

Once energized, monitor vibration levels, temperature, and pressure.

Record all findings and maintenance actions for future reference.
