Wherever you cannot use submersible pumps, these high-performance outdoor pumps are ideal. Since the pumps are not self-priming, it is best to choose a location that is lower than the bottom of the respective water container. This way, you can effectively protect the pumps against running dry. They can be operated with both a car battery and a power supply, giving you complete flexibility regarding the location and power source. Maximum operating time is 30 minutes. Continuous operation is not possible.
