The Grundfos 96455086 Kit Shaft Seal is a high-quality replacement part made for CR/I/N 1S/1/3/5 series pumps. It provides consistent sealing performance in tough industrial and marine settings. This HQQE mechanical seal set stops leaks, makes pumps last longer, and makes sure that water circulation, pressure boosting, and fluid transfer systems work at their best.

The Grundfos 96455086 shaft seal kit is a direct OEM replacement. It has a strong HQQE design and comes with two seal sizes (12mm and 16mm) that work well with Grundfos CR, CRI, and CRN vertical multistage pumps. It replaces previous Exxx seals with better HQQE technology, which makes them more resistant to corrosion and able to handle up to 16 bar of pressure. This kit is great for e-commerce sites like yours that sell marine parts (like ndmarinetech.com and technomarinespares.com). It improves SEO with keywords like “Grundfos shaft seal kit,” “HQQE seal 12mm,” and “CR 1/3/5 pump repair,” which brings in organic traffic from technical buyers looking for long-lasting pump maintenance solutions.

Usage Instructions

Preparation:

• To safely get to the shaft, turn off the power, drain the pump fluid, and take off the motor and coupling protectors.
• Use a 2.5mm Allen wrench to loosen the set screws and a 36mm socket on the shaft pin to pull out the old seal.

Installation:

• Use soapy water to lubricate the new O-rings and shaft. Then, put the kit onto the shaft and hand-tighten it before tightening it to 35 Nm.
• Align the shaft pin in the middle, tighten the set screws equally, and put the motor and coupling back together in a crisscross pattern.

Testing and Upkeep:

• Reconnect guards, prime the pump, and run it at a low speed to look for leaks. Check for wear every three months.
• Keep the kit in a cool, dry area. It’s great for regular maintenance on the marine pumps you have in stock.
