It features a 4-chamber design with self-priming capabilities and can operate dry without damage. The pump is equipped with a demand-type pressure switch that activates automatically when pressure drops, ensuring consistent performance and energy efficiency. With a maximum flow rate of 10.0 lpm (2.7 gpm) and a pressure of 17 psi (1.2 bar), this model is perfect for low to medium-pressure applications. It is also designed to handle seawater, making it suitable for marine environments. The motor operates on 12V or 24V DC power and comes with thermal overload protection that starts working at temperatures above 90°C (±10%). The pump includes a 1-year warranty from SEAFLO, offering peace of mind and reliability. ### Technical Details: | Motor Voltage | 12V / 24V DC | |---------------|--------------| | Type | 4 Chamber Diaphragm Pump, Self-Priming, Dry Run Capable | | Mode | Demand | | Certifications | CE Approval | | Liquid Temperature | Max 140°F (60°C) | | Priming Capabilities | 6 Feet (1.8 m) | | Max Pressure | 40 psi (2.8 bar) | | Max Flow Rate | 17 lpm (4.5 gpm) | | Thermal Overload Protected | Yes, activates at 90°C | | Inlet/Outlet Ports | 10/13mm Pyramid Hose Barb, 13mm Angle Hose Barb, 1/2" NPT Thread Filter | | Duty Cycle | Intermittent (varies with pressure) | | Motor Options | 2 Pin Connector, On/Off Switch | ### Model Comparison Table: | Model | Switch | GPM/LPM | PSI/BAR | Max Draw (A) | Valves | Diaphragm | Ports | Voltage | Wire Connections | |-----------------|----------|-------------|--------------|--------------|--------|----------------|----------------|---------|------------------| | SFDP1-027-017-41 | Demand | 2.7/10.0 | 17/1.2 | 4.5 | EPDM | Santoprene | Quick Attach | 12V | 2-Pin/Leads | | SFDP2-027-017-41 | Demand | 2.7/10.0 | 17/1.2 | 2.0 | EPDM | Santoprene | Quick Attach | 24V | 2-Pin/Leads | | SFDP1-033-035-41 | Demand | 3.3/12.5 | 35/2.4 | 8.0 | EPDM | Santoprene | Quick Attach | 12V | 2-Pin/Leads | | SFDP2-033-035-41 | Demand | 3.3/12.5 | 35/2.4 | 4.0 | EPDM | Santoprene | Quick Attach | 24V | 2-Pin/Leads | --- ### How It Works: The diaphragm pump is driven by an AC or DC motor, which powers a valve assembly containing multiple chambers. Each chamber has a diaphragm behind it, and as the motor turns, a cam mechanism causes the diaphragms to move back and forth. This motion creates suction, drawing fluid through the inlet and pushing it out through the outlet via check valves. The flow rate depends on factors such as the number and size of the chambers, cam offset, operating pressure, and fluid viscosity. This makes the pump highly adaptable for various applications. ### Additional Information: - **Color Options:** Black or as required - **Warranty:** 1-Year SEAFLO Warranty - **Application Areas:** Agriculture, Yacht, RV, Caravan, Sprayer Fixtures, Food & Beverage Filling, and Any Pressurization System This pump is a reliable and durable choice for those seeking efficient, long-lasting water pumping solutions in both residential and commercial settings.
