GRUNDFOS CRN Stainless Steel Vertical Multistage Centrifugal Pump
1.Corrosion Resistance and Material Advantages
Constructed from high-grade stainless steel (EN 1.4401/AISI 316), making it suitable for corrosive liquids (such as acids, alkalis, oils, and alcohols) and demanding operating conditions (such as marine applications and high-humidity environments).
2.High-Pressure and High-Temperature Capability
Supports a maximum operating pressure of 50 bar; an air-cooled shaft seal chamber design allows for handling high-temperature liquids up to 180°C (with a pressure limit of 25 bar), meeting industrial high-temperature requirements.
3.High Hydraulic Efficiency
Optimized through simulation-based design to lower NPSHr (Net Positive Suction Head Required) and reduce pressure losses, thereby enhancing hydraulic efficiency and overall performance.
4.Versatile Application and Customization
Widely used in ultrafiltration, reverse osmosis, mechanical cooling, distillation systems, water treatment, and more; supports customized AISI 316 stainless steel versions to meet specific requirements.
5.Compact Design
The inline multistage structure saves space, making it ideal for installations with limited room while maintaining high flow rates and adjustable pressure capabilities.
This product is engineered for complex fluids and harsh environments, combining durability, high efficiency, and versatility.
