Feature : The R385 requires between 6 12V DC and between 0.5 0.7A and will deliver its maximum operating values when power is at the upper end of these ranges. The pump can handle pumping heated liquids up to a temperature of 80 C and when suitably powered can suck water through the tube from up to 2m and pump water vertically for up to 3m. This immersible pump can be used to water your plants, make a fountain or waterfall, and even change your fish tank water. It works quietly with the sound level under 30db. The pump has a filter inside as well as a suction cup which can help stick it to smooth surfaces tightly.
