PP Magnetic Drive Pump – Sealless Polypropylene Chemical & Acid Transfer Pump
Product Overview
Our PP Magnetic Drive Pump | Sealless Chemical Acid Pump are engineered for the absolute safe, 100% leak-proof transfer of highly corrosive chemicals, hazardous liquids, and aggressive industrial effluents. By utilizing an innovative sealless design powered by an advanced magnetic coupling mechanism, these pumps eliminate the traditional mechanical seal entirely, the number one cause of pump failure and dangerous chemical leakage.
Constructed with a premium Polypropylene (PP) body and impeller, this series offers outstanding chemical resistance against aggressive acids, alkalis, and electroplating fluids, making it the safety gold standard for modern chemical process lines.
Key Features & Benefits
100% Leak-Proof Sealless Design: Driven by permanent magnetic coupling, eliminating fluid seals completely to provide total containment of hazardous or toxic chemicals.
Corrosion-Resistant PP Construction: High-grade Polypropylene pump body and internal impeller withstand aggressive acids (like Hydrochloric and Sulfuric acid), alkalis, and reactive process fluids.
Zero Maintenance Seal Fatigue: Without a mechanical seal to wear down, replace, or weep, operational downtime and maintenance costs are drastically cut.
Permanent High-Strength Magnets: Heavy-duty magnetic alignment ensures synchronized, slippage-free torque transmission from the motor shaft directly to the internal impeller.
Robust Motor Coupling: Mounted to a rugged Cast Iron (CI) motor frame running at a high-velocity 2900 RPM for efficient and consistent flow rates.

1. Absolute Prohibition of Dry Running
Because a magnetic drive pump uses the fluid being pumped to lubricate and cool the internal bearings, the pump must never be run dry. Even a few moments of operating without liquid can cause intense frictional heat buildup inside the PP shroud, damaging the internal sleeve bearings. We strongly advise using a dry-running protector or flow switch inside the line panel to cut off power if the fluid line goes empty.
2. Managing Maximum Fluid Temperature
Our PP Mag Drive series is rated to handle fluids up to a maximum temperature of 65°C. If your industrial process line drops below freezing or climbs past this threshold (such as highly concentrated hot sulfuric lines), please reach out to our application desk to discuss alternative engineering thermoplastics like PVDF.
3. Magnetic Decoupling Protection
If the fluid viscosity significantly exceeds design limitations, or if a large foreign object jams the impeller, the outer drive magnet will uncouple from the inner magnet. This built-in safety feature protects your motor from burning out, but it requires stopping the motor completely, clearing the obstruction, and restarting the pump to allow the magnetic fields to snap back into synchronization.
