    Offshore water pump.

    Tugboat, There is no test rig and and the pump was a fraction of what you estimate.The piping can be used again?When cleaning the assets cost hundreds of thousands to clean manually each year then it is small change.The pump will not go to waste neither will the knowledge gained on this...

    Tugboat, All this equipment? A pump? What are you going on about? I’m in the process of sourcing a submersible pump suitable for the job?? There has been some good knowledge and experience shared on this forum, don’t post if you have nothing constructive.

    Artisi, Mess? Nothing is installed? That’s the whole point of test stages? Leave you to your manly big pumps.

    Hi Littleinch, Would it be possible to email you some further details and clarify some of the points we have discussed so far? jamesss48@hotmail.com

    Offshore water pump.

    Hi Littleinch, yes just an open container with a timer to get the l/m is all i had to hand. I see what you are saying about introducing a restriction however, if my duty point is 1 bar at 130 l/m and i match the flow rate of all the nozzles combined to 130 l/m ensuring the nozzles...

    Hi Litleinch. Thanks Again for your reply and information shared. I appreciate your break down and correcting me on the pump rating versus duty point values as this is obviously critical.Whilst i am certain i am getting 130 l/min (which i was able to measure) the pressure must only be at 1...

    Offshore water pump.

    Thanks for the info guys it is very much appreciated. My mistake the pump is rated at 160l/m at 50m By the time you take into account around 7 metres suction head and 7m discharge head, pipe resistance and non return valve resistance I am receiving around 130-140l/min just under 3 bar Which...

    Hi little inch, I don’t really understand what you are asking.I require around 3 bar of pressure at a rate of 140l/m at the access level where the bird waste problem is.The water supply will then be connected to various spray nozzles which will disperse the bird waste. The 50m...

    Offshore water pump.

    Hi tugboat, I don’t see how that makes any difference, water is being sucked from the sea in both systems..the same amount of liquid will be displaced up the suction pipe (on self priming pump) as up the discharge pipe on a sump pump? Just to be clear, I’m not opposed to using a submersible...

    Offshore water pump.

    Ed stainless, thanks for your reply. If someone recommended a sump pump that will have a longer life than 5 years in saltwater and can be installed in such a way whereas marine growth, mussels/barnacles don’t pose a threat that has a head of 50 meters/180 l/m then I would be interested.I have...

    Offshore water pump.

    Hi Little inch, Not sure why you have some sort of a problem with everything I write.I thought this was a forum for assistance and ideas, everyone else seems to get that. Marine growth is also a massive problem, barnacles and mussels would soon Take hold of anything submerged in the water...

    Offshore water pump.

    Hi Artisi, No unfortunately, i could incorporate a compressor into the system however i was wanting to keep it as simple as possible. If i have no luck with the automatic breather then i will have no choice other than to build a two start process into the system. I would like to...
