Creating a jellyfish friendly
circulation system
Precision Pipework was asked if it could come up with an idea to circulate seawater in an observation tank containing jellyfish - while not damaging these delicate creatures
The formation of a new plastic division to handle the in-house manufacture of thermoplastic tanks, covers, coupling guards etc came in very useful when Precision Pipework was asked if it could come up with an idea to circulate seawater in an observation tank containing jellyfish It transpired that these delicate creatures suffered damage when in contact with the tank sides due to water movement during water circulation

Water drain valves for use with oil storage tanks
Alan Cobham has won an order to supply a number of density-sensitive water drain valves for a Middle East oil company, for use when draining water from the bottom of oil storage tanks
The damage to the jellyfish also lead to a short lifespan, requiring frequent replacement.
Lead plastics engineer, John Watts, conducted simple experiments with view to create a jellyfish friendly circulation system and coupled this with a newly designed tank overflow area.
Materials used were Durapipe ABS pipework and poly-propylene sheet.
The brief also required a design which blended into the tank to assist the viewing public.
The final design was asthetically pleasing and our last report indicated a previously high mortality rate now reduced to almost zero.
It should be remembered that the constant restocking had been undertaken at considerable cost and we would suspect that the payback time was very short.
The "Jellyfish" project is one of many "engineering solutions" provided to clients over the last forty-four years and in the course of our core business as pumping engineers has tended to take remain largely hidden from view, only surfacing when clients asked specific questions when trying to overcome a problem.
Recent reviews of the company's activities has brought home the extent of the special projects undertaken for this most rewarding side of the company, rewarding mainly from client satisfaction and our chances to create some unique equipment.
