Product Introduction

The CQL Stainless Steel Magnetic Pump is a high-performance, seal-less, magnetically driven pump designed for safe, reliable, and efficient transfer of aggressive, corrosive, or high-purity liquids. It is widely used in chemical, pharmaceutical, food, beverage, and industrial applications where leakage prevention, contamination-free operation, and low maintenance are critical.

Unlike conventional centrifugal pumps that rely on mechanical seals prone to leakage and wear, the CQL Stainless Steel Magnetic Pump employs magnetic coupling technology, eliminating the need for direct mechanical contact between the drive and the impeller. This seal-less design provides completely leak-free operation, preventing fluid loss, environmental contamination, and safety hazards.

Constructed entirely from high-grade 316L stainless steel, the CQL Magnetic Pump offers excellent corrosion resistance, chemical compatibility, and durability. Its precision-engineered impeller and magnetic coupling system deliver smooth, vibration-free operation while maintaining high efficiency across a wide range of flow rates and pressures.

The pump is also designed to handle viscous fluids, solvents, acids, alkalis, and high-purity liquids, making it suitable for chemical dosing, food processing, pharmaceutical production, and laboratory applications. Its compact, modular design allows easy integration into existing pipelines, production lines, or custom process systems.

Operating Instructions

Pre-Start Checks

• Verify alignment with motor and piping system.

• Ensure pump casing and magnetic coupling are free from debris.

• Confirm electrical connections and motor voltage compatibility.

Start-Up Procedure

1. Fill the pump casing with liquid to avoid dry running.

2. Energize the motor gradually to reach operational speed.

3. Observe pump for vibration, noise, or unusual heating.

4. Monitor flow rate and pressure gauges for normal operation.

Normal Operation

• Maintain fluid viscosity and temperature within pump specifications.

• Use VFDs for precise flow and pressure control.

• Regularly monitor the magnetic coupling for proper operation.

Shutdown Procedure

• Gradually reduce motor speed.

• Flush pump with compatible solvent for viscous or aggressive fluids.

• Inspect impeller, bearings, and magnetic coupling after shutdown.

Maintenance Guidelines

1. Visual Inspection

• Check pump casing, impeller, and magnetic coupling for wear or corrosion.

2. Bearing Check

• Inspect bearings for noise, vibration, or wear. Replace if necessary.

3. Magnetic Coupling Maintenance

• Ensure magnets are intact and aligned correctly.

• Verify that coupling gap meets manufacturer specifications.

4. Cleaning

• Flush pump after use with compatible solvent, particularly for sticky or corrosive fluids.

5. Periodic Overhaul

• Recommended every 6–12 months depending on fluid type and operating conditions.

• Inspect impeller, magnetic coupling, and housing for wear or corrosion.

6. Lubrication

• Most CQL Magnetic Pumps are self-lubricated by the pumped fluid; no external lubrication required.
