Stainless Steel Centrifugal Pump
Material Core: Exclusive Design for Stainless Steel
Made of 304/316L stainless steel as the core material, the stainless steel centrifugal pump is specially designed for conveying corrosive fluids or hygienic fluids. Relying on excellent corrosion resistance and cleanliness, this stainless steel centrifugal pump has become an exclusive model in chemical, food and other industries. Its working principle is consistent with the basic model, but the flow path components (pump casing, impeller, suction chamber) are all precision-cast with stainless steel, with a smooth surface without dead corners, which not only avoids medium corrosion but also meets hygienic requirements.
Structural Design and Key Performance
The structural highlight lies in the adoption of an integrated stainless steel pump body, which reduces the number of sealing surfaces. Equipped with food-grade mechanical seals, the stainless steel centrifugal pump prevents medium pollution and leakage.
The performance parameters are targeted and optimized
