Pump to use with underwater suction cups
Pump to use with underwater suction cups
(OP)
Hi all, forgive my naivety when it comes to pumps but I would like some advice on pump selection for a couple of suction cups I want to use. The Cups will be used sub sea so the media they will be pumping will of course be seawater. I have two suction cups I intend to use both separately but utilising the same pump. The first cup measures Ø250mm and is required to lift 70kg which I have been told it is easily capable of. The second cup is smaller at Ø150mm and is only required to lift 30kg. Neither cup will achieve a perfect seal due to the nature of the media they are lifting so the pump will have to run constantly to maintain suction. My question is what kind of pump will be most suitable for the task in hand? Centrifugal? How will it cope with the reduced flow once the suction cup is effectively engaged on the target? Anybody recommend a manufacturer that might be able to help?
Thanks
Thanks

I like the eductor idea, the fewer moving parts the better.
I have used ones from Fox for pulling vacuum in very dirty systems. I have also used them for pumping and mixing chemicals all in one step.

First up - get eductor selected / designed and then ask the forum again about what you need for the driving unit.
