Upgraded 33-Series 12V 3.0 GPM, 45 PSI Self-Priming Water Pressure Pump

Features

• Key Product Specifications: Model Number: ESDP1-030-045-33 | Operating Voltage: 12V | Open Flow Rate: 3.0 GPM (11.3 LPM) | Shut-Off Pressure: 45 PSI (3.1 BAR) | Self-Priming Height: 6 ft (1.8 m) | Max Fluid Temperature: 140F (60C) | Port Size: 1/2"-14 MNPT | Key Materials: EPDM Valves / Santoprene Diaphragm
• Automatic Adjustable Pressure Switch: Built-in automatic pressure switch starts and stops the pump based on water demand. Simply turn the screw to adjust the pressure cutoff from 17-60 PSI. It activates when a faucet opens and shuts off when closed for hands-free use in RVs, boats, campers, and off-grid cabins
• Ultra-Quiet Vibration Dampening Mount: Includes a noise-reducing rubber mounting base that minimizes vibration and operational noise. Suitable for quiet environments like RV interiors and marine cabins, it delivers smooth, silent performance without disruptive sounds, even under full load
• Self-Priming And Dry-Run Protection: The pump offers flexible installation with self-priming capability up to 6 feet. Its dry-run resistant design allows it to operate safely without water for short periods, preventing internal damage. This provides both installation freedom above tank level and reliable protection for intermittent-use systems
• High-Performance 3-Chamber Diaphragm: Engineered with an advanced three-chamber diaphragm that ensures a consistent 3.0 GPM flow at 45 PSI. This design reduces pump cycling, maintains stable water pressure, and enhances overall durability. Suitable for marine, RV, and off-grid applications that demand reliable moderate pressure and smooth, enduring performance
