12 volt, 20m head submersible water pump

12V High-Head Submersible Pump (20m Head)

Brand Chemical Supplies provides specialized low-voltage pumping solutions for demanding vertical lift applications. While standard 12V pumps typically offer limited lift, our High-Head 12V Submersible Pump is engineered with a high-torque motor and optimized impeller design to achieve a 20m vertical head, making it the premier choice for deep-well water extraction and high-elevation transfers in off-grid environments.

Technical Specifications

• Voltage: 12V DC.

• Maximum Head (Lift): 20m (2.0 \text{ bar} pressure).

• Flow Rate at Surface: Approximately 15L/min – 25L/min (Model dependent).

• Power Consumption: 120W – 180W (10A – 15A).

• Outlet Diameter: 12mm – 19mm (frac{1}{2}” to \frac{3}{4}” hose barb).

• Housing: Heavy-duty, corrosion-resistant Stainless Steel or reinforced Thermoplastic.

• Submersion Depth: Rated for continuous submersion up to 15m.

Key Features & Benefits

• Extreme Vertical Lift: Capable of pushing water up to a 20-meter elevation, perfect for steep terrain, multi-story buildings, or deep boreholes/wells.

• Solar & Battery Optimized: Specifically designed to run directly off 12V solar arrays (with a regulator) or deep-cycle battery banks without the energy loss of an inverter.

• Submersible Brushless Motor: High-efficiency motor technology ensures a longer lifespan and quieter operation compared to traditional brushed DC pumps.

• Dry-Run Protection: Higher-spec models include thermal overload protection to prevent motor damage if the water source runs dry.

• Compact Borehole Design: The slim profile allows the pump to fit into narrow well casings or tight storage tank openings.

Primary Applications

• Livestock Watering: Pumping from deep boreholes or wells into elevated header tanks for gravity-fed troughs.

• Remote Irrigation: Delivering water to hilltop nurseries or garden patches from lower-lying rivers or dams.

• Off-Grid Domestic Use: Providing pressurized water to cabins, tiny homes, or remote ranger stations located above the water source.

• Emergency Dewatering: Clearing deep shafts, basements, or technical pits where a standard utility pump lacks the necessary lift.

• Hydroponics & Aquaculture: Circulating water in large-scale systems requiring high-pressure filtration or aeration.

Usage & Installation Guidelines

• Power Source: Ensure your battery bank or solar setup can handle the constant 10A+ draw. Use thick gauge marine-grade cabling (4mm^2 or higher) to prevent voltage drop over long distances.

• Non-Return Valve: For a 20m lift, we strongly recommend installing an inline non-return valve near the pump to prevent water hammer and backflow when the pump stops.

• Duty Cycle: While built for performance, these high-head units should ideally be rested for 15 minutes after every 60 minutes of continuous operation to manage heat.

• Filtration: Always use the integrated suction strainer; for very sandy water, an additional fine-mesh pre-filter bag is recommended to protect the high-pressure impeller.
