Buy a small, low power 12V pump. Connect it straight to the panel. It'll run most of the time when the sun is shining. It probably will work just fine like JRE says. But there could be a slight chance that the panel will over-volt the motor if the motor does not need the whole 10 Watts. @jigneshsorathiya that one won't work, it's for AC power.
Also, there is chance your solar panel might create more than 12v power, in which your water pump will get damage in long run. To avoid this situation, you can simply connect DC buck converter between your solar panel and water pump which will help to supply only upto 12v power to your water pump.
The Solar Water Pump Sizing Calculator is an essential tool for individuals who rely on solar power to pump water. By providing the required input data, users can accurately calculate the minimum solar panel wattage and battery capacity required to meet their water pumping needs.
A 12v 10w solar panel will create DC power. You need a DC water pump if you want to run it directly from your solar panel. Also, there is chance your solar panel might create more than 12v power, in which your water pump will get damage in long run.
PV-DIRECT SOLAR WATER PUMP circuits should be sized not for the nominal voltage (i.e. 24V) but for the actual working voltage. In this case, the working voltage is approximately 34V. Without a battery to hold the voltage down, the working voltage will be around the peak power point voltage of the PV array.
