Robust Performance and Compatibility

Designed specifically for GRUNDFOS CR, NB, NK, and CH Series, this shaft seal seamlessly fits various industrial pumps. With a standardized 22mm size and 8mm thickness, it offers compatibility and versatility in diverse water and fluid-handling systems. The mechanical cartridge design streamlines installation and maintenance, minimizing downtime.

Superior Material & Corrosion Resistance

Crafted from stainless steel and advanced elastomeric O-rings (NBR or Viton), the seal resists corrosion and maintains integrity even in harsh environments. Its high tolerance (0.01 mm) ensures precise fitting and reduced wear, while its 70 Shore A hardness provides excellent durability for industrial tasks.

Extended Service Life

The seal operates reliably for up to 5,000 hours, even under pressures up to 10 bar and within a wide temperature range (-20C to 120C). Adhering to DIN 24960/ISO 3069 standards, it is perfectly suited for applications involving water, mild chemicals, and light oil.

FAQ's of Grundfos Shaft Seal:

Q: How do I install the Grundfos Shaft Seal in compatible pump models?

A: The Grundfos Shaft Seal features a cartridge installation type, making it straightforward to fit into GRUNDFOS CR, NB, NK, or CH Series pumps. Follow the standard installation process: ensure the shaft and housing are clean, align the seal to the correct position, and secure it according to the manufacturer's guidelines provided with the pump.

Q: What benefits does the mechanical shaft seal provide for industrial applications?

A: This shaft seal prevents leakage between the pump shaft and housing, maintaining system efficiency and safety. Its high corrosion resistance, extended lifespan, and ability to perform under pressures up to 10 bar ensure reliability in demanding industrial environments handling water, mild chemicals, and light oil.

Q: When should the Grundfos Shaft Seal be replaced?

A: Replace the seal after approximately 5,000 operating hours or sooner if you observe leakage, irregular pump noise, or reduced efficiency. Regular inspection and timely replacement help maintain optimal pump performance and prevent unplanned downtime.

Q: Where can this shaft seal be used effectively?

A: This seal is ideal for GRUNDFOS pump models, water pumps, booster sets, and various industrial fluid-handling systems. It is widely used by exporters, importers, manufacturers, and suppliers across diverse industries in India where fluid containment and equipment longevity are critical.

Q: What is the process for selecting the appropriate O-ring material for my application?

A: Choose NBR O-rings for general water and light oil services, or Viton O-rings for handling mild chemicals or higher temperature environments (up to 120C). Consider fluid type, temperature, and compatibility with your specific application before selecting the O-ring material.

Q: How does this product ensure corrosion resistance and withstand harsh media?

A: Constructed from stainless steel and equipped with durable NBR/Viton O-rings, the seal offers high corrosion resistance. This construction ensures reliable protection and performance even when exposed to water, light oil, or mild chemical media in challenging industrial environments.
