CQ-type magnetic drive pump
CQ-type magnetic drive pump (referred to as magnetic pump) is the permanent magnet coupling working principle applied to the centrifugal pump of new products, reasonable design, advanced technology, with a sealed, leak-proof, corrosion-resistant properties of its performance abroad The advanced level of similar products. Magnetic pump to replace the dynamic seal with static seal, the pump over-current components in a completely sealed state, completely solve the mechanical seal of other pumps can not be run, run, drop the shortcomings. Magnetic pump selection of corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc. as a manufacturing material, so it has good corrosion resistance, and can be transported medium from pollution. Magnetic pump structure then compact, beautiful appearance, small size, low noise, reliable operation, easy to use and maintenance. Can be widely used in chemical, pharmaceutical, petroleum, electroplating, food, film photographic printing, scientific research structure, national defense and other units to send acid, lye, oil, rare precious liquid, venom, volatile (excluding particles) And supporting the circulating water equipment, filter supporting. Especially easy to leak, flammable, explosive liquid axis delivery, the choice of this pump is even more ideal.
