About this item

  • Operates on 12 volts DC, making it suitable for battery-powered systems, such as those in vehicles, marine applications, and off-grid setups.
  • Capable of pumping 3.0 gallons per minute (GPM), which is ideal for medium-duty applications requiring a steady water supply.
  • The diaphragm technology prevents backflow, maintains consistent pressure, and provides superior resistance to wear and tear compared to impeller-based pumps.
  • Self-priming capability allows it to draw liquid up from a tank or reservoir even when mounted above the liquid level, reducing installation constraints.
  • Features an integrated pressure switch that automatically turns the pump on and off depending on demand, preventing unnecessary power consumption and wear.
  • Built with corrosion-resistant materials, making it suitable for freshwater, saltwater, and chemical applications.
  • Can run dry without damage, ensuring longevity and reliability even in situations where the fluid source temporarily runs out.
  • Compact and lightweight design facilitates easy installation and portability.
  • Mounting: Securely install on a firm surface using vibration-dampening mounts to reduce noise and movement.
  • Pressure Boosting Systems: Enhances water pressure in low-pressure plumbing setups.
