O-Ring for 50SPH70 Pump

The Water Treatment Center of a Tommy Car Wash Systems site relies heavily on the self-priming Goulds 50SPH70 pump to cycle, filter, and reclaim massive volumes of water. Because this 5 HP pump generates significant high-head pressures (up to 85 PSI), even minor gasket degradation can cause air leaks, leading to loss of prime, seal cavitation, and motor strain. Replacing your worn casing seals with the genuine 5K74 Buna-N O-ring guarantees a tight, watertight seal inside the pump head, ensuring continuous and trouble-free reclamation cycles.

Key features and benefits include:

• Perfect Match for Goulds 50SPH70 Pumps: Designed to fit perfectly inside the cast iron casing and diffuser assembly of your 5 HP Prime Line SP-Series commercial water pump.
• Industrial Buna-N Construction: Formulated from high-density nitrile rubber (Buna-N) to withstand continuous chemical exposure from car wash reclaim water, low-pH detergents, and abrasive tunnel grit.
• Leak-Proof Casing Seal: Prevents air from entering the suction side of the pump, allowing the 50SPH70's self-priming check valve to function at maximum efficiency.
• Minimizes Maintenance Downtime: The back pull-out design of SP-series casings means a quick O-ring swap can be completed in minutes during scheduled tunnel service windows.
