Battery powered water pumps designed for situations where mains electricity is not available, not safe or not practical. From off-grid sites and vehicle-mounted systems to window cleaning, spraying, emergency drainage and remote installations, our 12V and 24V range covers the most common professional and domestic applications.
Battery operation gives you complete independence from mains electricity. Common reasons customers specify battery powered pumps include:
The deeper read: what's in this range, how to pick, and when to talk to us before you buy.
Our submersible battery powered range comes from Umbra Pompe, an Italian manufacturer specialising in 12V and 24V pump systems. The Baby Battery range is suited to sumps, bilges, industrial use, leisure, processing, transfer and filling applications.
Two models are available:
Both models are available in manual or automatic versions and come with 5m of PVC power cable fitted with crocodile clips for direct battery connection. Solely battery operated with no mains option.
For applications where the pump sits above the water source rather than in it, we supply the FL Demand Pump. This is an automatic diaphragm surface pump particularly popular with professional window cleaners using pole-fed water systems.
The FL Demand Pump is widely used for:
The FL40 model is battery powered, available in either 12V or 24V DC.
Why the FL Demand Pump Stands Out
The pump switches on and off automatically when a valve, tap or hose attachment is opened or closed. Because it uses a diaphragm rather than an impeller, it does not require priming and can run dry without damage. This makes it forgiving in real-world use where water supply may be inconsistent.

No. Our battery powered pumps connect to a separate 12V or 24V battery using the supplied cable and clips. This gives you flexibility to use a vehicle battery, leisure battery or dedicated power supply suited to your runtime requirements.
Runtime depends on battery capacity and pump load. As a rough guide, a Baby Battery 12 drawing 175W will run for approximately 4 to 6 hours from a 100Ah leisure battery before voltage drops too low. The FL40 is significantly lower draw and will run considerably longer per charge.
Yes. The crocodile clips on a Baby Battery connect directly to a vehicle battery. For continuous use we recommend running the engine or using a dedicated leisure battery to avoid draining the starter battery.
Voltage and flow. The Baby Battery 12 runs on 12V DC and pumps 55 litres per minute. The Baby Battery 24 runs on 24V DC and pumps 69 litres per minute, drawing more power but delivering higher flow. Choose based on the battery system you have available and the flow rate you need.
No. The FL Demand Pump is a surface pump that sits outside the water source. It draws water through a hose connected to the inlet. Because it is a diaphragm pump, it can run dry without damage and self-primes from connected supply lines.
Yes. The FL Demand Pump is widely specified by professional window cleaners using pole-fed deionised water systems. It runs from a battery, switches on automatically when the trigger is opened, and switches off when closed. The high head rating makes this well suited.
