Shaft Seal for 5HP RO Pump

This genuine replacement part is the critical line of defense for the high-pressure vertical multistage pumps found in Tommy Car Wash Systems’ Reverse Osmosis (RO) units.

Specifically engineered for the CR, CRI, and CRN pump series, this cartridge-style seal is designed to handle the unique demands of purified water delivery, where maintaining high pressure is non-negotiable for tunnel performance. The HQQE seal designation signifies a rugged construction of Silicon Carbide (SiC/SiC) faces with EPDM elastomers. This combination is ideal for the RO backroom environment, offering superior resistance to wear and the specific chemical profile of treated car wash water.

Key features and benefits include:

• Silicon Carbide Faces: Extremely hard surfaces that resist abrasion from any microscopic particulates, ensuring a longer lifespan than standard carbon seals.
• Plug-and-Play Cartridge: The 12 mm cartridge design allows for a "blind" installation—no measuring or specialized spacers required to set the seal height.
• EPDM Elastomers: Specifically chosen for its excellent recovery properties and resistance to the temperature fluctuations found in car wash equipment rooms.
• Genuine Grundfos Quality: Avoid the risk of third-party seals that can fail prematurely under high-pressure RO cycles.
