Layered Anti-corrosion Coating Treatment for Metal Structural Components Boosts Overall Service Life in Humid Coastal Industrial Zones

Coastal industrial areas are filled with salt mist, volatile acid gas and high air humidity. Although the flow contact parts of plastic chemical pumps have excellent corrosion resistance, exposed metal supports, bolts and motor outer casings are prone to rust and electrochemical corrosion after long-term exposure. Corroded metal fittings will cause pump installation looseness and motor casing damage, indirectly shortening the stable operation cycle of the whole pumping unit.

All metal structural accessories matched with Yida magnetic pumps, self-priming pumps and vertical pumps adopt multi-layer rust-proof and anti-corrosion spraying technology. The surface forms a dense protective film that isolates salt fog, acid mist and moist air from direct contact with metal substrates. Standard stainless steel fasteners are configured as default options for overseas coastal project customers.

The optimized metal anti-corrosion scheme enables the pump equipment to maintain stable mounting structure and complete appearance integrity under long-term coastal working conditions. It greatly reduces the frequency of metal part replacement for global coastal industrial projects and improves the overall environmental adaptability of the pump product system.
