51 Series 24V RV Water Pump Diaphragm, Self-Priming

The NJBVRS 51 Series 24V Water Pump Diaphragm is a heavy-duty, self-priming pump engineered for reliable water flow in RVs, boats, yachts, and car wash systems. Its five-chamber diaphragm design delivers up to 5.0 gallons per minute (GPM) with precise pressure control, ensuring stable performance even under fluctuating demands. Ideal for freshwater or saltwater applications, this pump supports up to four fixtures without requiring an accumulator tank, making it perfect for remote water systems like those in RVs, boats, or off-grid cabins.

Built for durability, the 51 Series features excellent sealing, waterproof and dustproof construction, and efficient heat dissipation. With a low starting pressure and dry-run protection, it minimizes cycling and reduces wear, extending pump life. The pump operates safely up to 60°C (140°F) and is compatible with both fresh and saltwater, making it a versatile choice for marine, automotive, and off-grid water systems.
