Quick question, if they run out of water and are left running for any length of time do they overheat? and if so how long does it take?

I suppose Jake that it could in a minute (very small) way. The motor is separated from the pump with a diaphragm in a hard 'plastic' housing. The casing of the motor is metal with 4 magnetic 'blocks'. It called a Permanent Magnetic DC motor or PMDC motor for short. This casing will be what the motor uses to dissipate any heat build up. If these magnets where replaced with a coil (field coil) made from copper wire then they would generate more heat. To run the motor as efficiently as possible (our batteries aren't a never ending power source) the motor must remain as cool as possible. Any heat generated in the motor is wasted power from the battery.I've inly heard of the odd Pearson who's had it running for about 45mins continuously who said it cut off due to heat build up, so guess they can fail from heat spruce? Also I would have thought the water would have some cooling effect on the motor?
Oops. Misread that. Sorry.No it wasn't run dry, just continuously for 45 minutes...
They always work behind buildings mate, mine does even at 70 odd meters round the back of an office, you just sometimes have to press it twice or hold it up a bit...Not sure about remote, I like the idea but I worry it will be unreliable and just add an extra layer of faff (and expense) and not entirely sure how well they would work when directly behind a building.
