Key Features
Superior Corrosion Resistance: The pump body is available in various chemical-resistant materials, including FRPP, CFRPP, PVDF, SUS304, and SUS316, allowing it to handle strong acids, alkalis, and highly aggressive fluids with ease.
Dry-Running Capability: The innovative design allows the pump to operate without liquid (dry-run) for extended periods without damage, eliminating the common issue of pump failure due to dry-running.
Safe Sealless Design: Utilizing a dry-type sealless structure prevents corrosive vapors and acid mist from entering the motor through the shaft, protecting the bearings from corrosion.
Enhanced Protection: The motor features a multi-layer anti-corrosion coating and a high waterproof rating, ensuring long-term durability and safety in humid and corrosive atmospheres.
Typical Applications
PCB/FPC Industry: Etching, electroplating circulation, and chemical processing.
Environmental Engineering: Exhaust gas scrubbing, acid-wash wastewater treatment.
Surface Finishing: Electrophoretic coating, continuous electroplating, and metal cleaning.
Advanced Manufacturing: Semiconductor production, new energy battery material processing, and fine chemicals.
