Among various centrifugal pump products, stainless steel centrifugal pumps have become the preferred equipment in multiple industries due to their excellent material properties and wide application.
I. Application scenarios of stainless steel centrifugal pumps
1. Chemical and pharmaceutical industries: used to transport corrosive media such as acid/alkaline solutions, pharmaceutical liquids, and injectable solutions. The material of stainless steel centrifugal pumps meets food hygiene standards, thereby ensuring drug purity and quality while preventing cross contamination.
2. Food and beverage processing: When transporting alcohol, juice, and dairy products, it is worth noting that stainless steel centrifugal pumps meet hygiene standards and easy-to-clean requirements.
3. Environmental protection and water treatment: Compared with ordinary carbon steel, the excellent chloride ion corrosion resistance of stainless steel centrifugal pumps makes them very suitable for chlorine-containing wastewater treatment and seawater desalination systems.
4. Industrial circulation system: The high temperature resistance and air-water prevention capabilities of stainless steel centrifugal pumps reduce maintenance downtime in cooling water flow circulation and boiler feed water applications.
II. Suitable media for stainless steel centrifugal pumps
1. Moderately corrosive liquids
Typical media: dilute sulfuric acid, weak acids/bases, organic solvents (ethanol, acetone)
2. Food grade and high purity liquids
Typical media: milk, juice, edible oil, pharmaceutical intermediates
3. High temperature liquids
Typical media: hot water (≤105°C), hot oil, boiler feed water
4. Wastewater containing particles
Typical media: mineral water, wastewater ≤1.5% solid content
III. Core advantages of stainless steel centrifugal pumps
Made from 304/316 stainless steel, these stainless steel centrifugal pumps combine corrosion resistance, high temperature tolerance and hygienic compliance:
1. Corrosion resistance: The chromium in stainless steel centrifugal pumps forms a protective oxide film that resists corrosion from acid, alkali and saline solutions.
2. High temperature endurance: Suitable for culture media from -20°C to 150°C, special models can withstand short-term exposure to 200°C.
3. Hygienic safety: Smooth, non-porous surface meets food/drug hygienic standards to prevent cross contamination.
4. Energy efficiency: Stainless steel centrifugal pumps operate 10%-20% more efficiently than conventional cast iron pumps, reducing long-term costs.
IV. Usage precautions
1. Avoid highly corrosive media (e.g. hydrochloric acid > 30%, hydrofluoric acid) and molten metals. Special material treatment is required to prevent intergranular corrosion at high temperatures.
2. Observe temperature and solid content limits: Stainless steel centrifugal pump standard models operate at ≤150°C. For media with solids > 1.5%, choose wear-resistant blades or enlarged flow channels.
3. Prevent drying, perform regular cleaning, and flush immediately after transporting viscous media to avoid residual solidification.
