CQ Stainless Steel Magnetic Drive Pump

What is CQ Stainless Steel Magnetic Drive Pump？

Q1: Is the CQ stainless steel magnetic drive pump suitable for self-priming applications without a vacuum priming tank?

No.Magnetic drive pumps must be operated under flooded suction conditions or paired with a priming tank. Dry running without liquid will rapidly generate friction heat, causing severe damage to the internal bearings and demagnetization of the magnetic coupling.

Q2: What grade of stainless steel is used for the wet-end parts to handle organic solvents or organic acids?

304, 316L, 2205, or 2507 Stainless Steel.

The liquid-end components (pump body, impeller, and rear casing) are typically cast from 304, 316L, or duplex stainless steels such as 2205 and 2507. This makes the CQ pump highly effective for organic solvents, mild acids, aggressive chemical media, food-grade fluids, and pharmaceutical mediums, while offering high mechanical strength compared to plastic alternatives.

Q3: How does the sealless design protect high-value or hazardous liquids from loss and contamination?

Through a static seal isolation sleeve structure.

Instead of traditional dynamic mechanical seals that wear over time, the CQ pump uses static O-rings to seal the containment shell. Power is transmitted wirelessly via internal and external magnetic couplings, ensuring 100% zero leakage and zero environmental contamination for precious or toxic liquids.

Q4: Can low-power micro models (0.025 kW – 0.12 kW) be integrated into small equipment skids?

Yes. The micro-power models in the CQ series feature micro-flange or threaded connections (e.g., DN6/DN10) and an ultra-compact body. They are designed for tight-space OEM machinery integration, such as laser cooling units, medical filtration systems, and laboratory sampling loops.
