Güde RFP 12-201-04 Battery-Powered Rainwater Tank Pump – 1500 l/h, 11 m, Li-Ion 12V
The RFP 12-201-04 pump is a specialized solution for domestic and semi-industrial rainwater harvesting systems. Unlike traditional submersible pumps, the RFP 12-201-04 is self-contained – powered by an integrated lithium battery, it does not require a 230V mains power connection. Ideal for cellars, gardens, basements where a power outlet is not available, or for emergency situations (flooding, power outages).
The telescopic tube, adjustable from 540 to 1000 mm, adapts to any tank or well depth without the need for external tube extensions. The flow rate of 1500 liters/hour is adequate for draining medium rainwater collection tanks or for intermittently supplying garden irrigation systems. The head of 11 meters allows water to be transported up to 11 meters of vertical height.
The dry-running protection automatically deactivates the pump if the tank empties, protecting the pump from cavitation damage. The battery charge status indicator (visual LED) allows the operator to constantly check the available charge without external instruments. Battery charging time: 360 minutes (6 hours) via the included charger.
Distinctive features:
-
12V, 2.0 Ah lithium battery – Total autonomy from the mains. Ideal for cellars, gardens, remote areas without power.
-

Frequently asked questions
What is the flow rate of the RFP 12-201-04 and how long does it take to drain a medium tank?
1500 liters/hour is equivalent to 25 liters per minute. For a medium 500-liter tank, theoretical drainage time: 500 l ÷ 25 l/min = 20 minutes. For 1000 liters: 40 minutes. Actual time depends on the head (if the tank is 5 meters below the discharge point, the effective flow rate drops to ~800 l/h, doubling the times).
How long does the lithium battery last during continuous operation?
The 2.0 Ah 12V (24 Wh) battery lasts approximately 6-8 hours of continuous operation depending on the head used. For intermittent use (10-15 minute cycles with breaks), a charge lasts 1-2 weeks of light daily use. Full charging time: 360 minutes (6 hours) via the included charger.
What is the maximum head of 11 meters and how does it affect flow rate?
The 11-meter head is the maximum height to which the pump pushes water vertically. At zero head (horizontal discharge pipe), the flow rate is a maximum of 1500 l/h; at 5 meters height, the flow rate drops to ~1000 l/h; at 11 meters, the flow rate drops to ~200 l/h (operating limit). For uphill applications (low tank to high terrace), evaluate the specific head required.
What is the advantage of the adjustable telescopic tube?
The telescopic tube 540-1000 mm eliminates the need for external extensions. If the tank is 700 mm deep, the tube adjusts automatically without cutting or adding sections. Adjustment: (1) empty the tank, (2) extend/compress the tube to the desired length, (3) fix with locking rings. No special tools are needed.
What does "dry-running protection" mean and why is it important?
Dry-running protection automatically deactivates the pump when the water level in the tank drops below the suction tube inlet. If it weren't present: the pump would suck in air, causing cavitation (air bubbles in the circuit), damaging seals and the motor. The integrated sensor detects when suction is only air, shutting down the pump and protecting it from permanent damage.
Is the supplied charger compatible with any worldwide outlet?
Yes, the charger accepts 100-240V, 50-60 Hz – compatible with any worldwide outlet (Europe, North America, Japan, Australia, etc.). If traveling abroad for the first time, a simple mechanical adapter for the outlet is sufficient (a voltage converter is not needed).
What is the maximum immersion depth of the pump?
The pump can be immersed up to approximately 4 meters (the telescopic tube is a maximum of 1 meter long, so up to 1 meter from the bottom + pump body below). If the tank is very deep (>4 m), consider professional submersible pumps. Dry-running protection prevents damage if the tank empties during a cycle.
Is the lithium battery safe and what is its lifespan?
The Güde lithium-ion battery is CE and GS certified. Estimated lifespan: 500-1000 charge-discharge cycles (1.5-3 years with moderate daily use). After 1 year, capacity drops to ~90% of original; after 2 years, to ~80%. Storage: if not used for >3 months, recharge at least once a month to preserve the chemical health of the lithium cell.
