Grundfos 96511845 Shaft Seal Kit

Ensure your Grundfos vertical multistage pumps maintain optimal performance with the 96511845 Shaft Seal Kit. As a veteran in the field, you know that a pump seal replacement is critical for preventing leaks and maintaining system pressure in high-demand environments. This HQQV shaft seal is a cartridge-style unit specifically engineered for CR, CRI, and CRN models (specifically sizes 10, 15, and 20). It features a robust 16mm diameter and is constructed with Viton (FKM) elastomers and Silicon Carbide (SiC/SiC) seal faces, providing superior chemical resistance and durability in commercial HVACR and industrial water applications. With a maximum pressure rating of 30 bar, this kit is built for high-head, high-pressure duty cycles where standard seals often fail. Replacing your Grundfos CR seal with this genuine OEM pump repair kit ensures exact tolerances and eliminates the compatibility risks associated with generic alternatives. This kit is the direct replacement for legacy part numbers including 96511836, 96511844, and 96511841, streamlining your inventory and truck stock.

• Enhanced Durability: Silicon Carbide seal faces provide excellent wear resistance against abrasive particles and high-velocity fluids.
• Broad Compatibility: Engineered for use across the Grundfos CR/CRI/CRN 10, 15, and 20 series, ensuring a perfect fit for multi-stage centrifugal pumps.
• High Pressure Reliability: Designed to withstand operating pressures up to 30 bar without compromising the stationary or rotating seal interface.
• Simple Installation: The cartridge-style design reduces the risk of incorrect assembly and shortens downtime during field service calls.
• Viton Elastomers: Provides high thermal stability and resistance to a wide range of oils and chemicals.

What does the HQQV designation signify?
The HQQV code indicates a cartridge O-ring seal with Silicon Carbide (Q) seal faces and Viton (V) elastomers. It is ideal for water and various glycol solutions common in hydronic systems.

Is this kit compatible with CR 10-1 through CR 20-17 models?
Yes, this seal kit is the standard replacement for the CR/CRI/CRN 10, 15, and 20 product lines across various stage configurations.

Can I use this seal for high-temperature applications?
This Viton-based seal is rated for standard vertical multistage pump temperatures; however, always verify the specific medium and temperature range against the Grundfos technical datasheet for your specific pump curve.
