If you want submersible then nothing other than tsurumi. We bought dozens a year and wasted weeks trying to get them to prime. Bought a tsurumi for one gang last year and it's brilliant. Lasted a year and still perfect and primes perfectly Everytime straight away, so every gang now has one. We only have 50mm ones but hired 75mm ones to empty ponds.

I have a 50mm tsunami, like you say they are bloody brilliant!! Only annoying this is it’s the float switch version, gets abit frustrating sometimes! Switch is cable tied to the pullout rope
If you take the 2 screws out of where the cable goes in you can pull the cable and float switch out, unplug the switch and put just the cable back in you just need 2 shorter screws

I’ve a 2” cutter pump from machine mart not sure of the make but frightfully heavy and throws the water out but is on a big float switch which most the time only pumping 2-3 feet out so have to try stick ontop so it’s runs.

Shame them don’t have an internal one let’s them run to lower level

got one of these to help with flooding, it puts out a massive amount of water. no worries about electric going off as it runs of beaver pack.
