🌊 Reliable Pumping Solutions: Grundfos CR & CRN Pumps at Inline Sales & Service Ltd.
When it comes to dependable, high-performance pumping systems for industrial, commercial, and municipal applications, few names stand out like Grundfos. At Inline Sales & Service Ltd., we’re proud to offer Grundfos CR and CRN multistage centrifugal pumps — robust solutions that have set industry standards for efficiency, versatility, and longevity.
🚀 What Makes Grundfos CR & CRN Pumps Exceptional?
Grundfos CR series pumps are vertical, inline, multistage centrifugal pumps engineered to handle a wide spectrum of liquids and operating conditions. They’re celebrated for their compact design, ease of installation, and excellent efficiency — making them perfect for applications ranging from pressure boosting and water supply to industrial processes and HVAC systems.
Here’s what sets them apart:
- Modular design for flexibility: CR pumps are built with modular stages and components, allowing customization to match specific job requirements.
- Material options: Available in cast iron, stainless steel (including high-grade 316 stainless steel for CRN models), and even titanium for aggressive or corrosive environments.
- High efficiency and energy savings: With premium motors and optimized hydraulics, these pumps reduce operational costs while delivering reliable performance.
- Service-friendly design: Feature balanced shaft seals and laser-welded impellers for long service life and easier maintenance. (🛠️ CR vs. CRN — Choosing the Right Pump for the Job
While all CR series pumps share the same core design benefits, the CRN variant is crafted with high-grade stainless steel wetted parts, making it especially suited for corrosive or challenging liquids — from chemical process fluids to brackish water.
| Feature | CR | CRN |
|---|---|---|
| Material | Cast iron + Stainless wetted parts | High-grade stainless steel (EN 1.4401) |
| Best Use | General water and industrial applications | Corrosive, industrial fluids and aggressive environments |
| Corrosion Resistance | Standard | Enhanced |
| Typical Applications | Water supply, boiler feed, pressure boosting | Filtration, RO systems, acids/alkalis, industrial processing |
This makes the CR series a go-to for standard pumping needs, while the CRN series excels where materials and reliability under tough conditions matter most.
