Concrete Volute Pumps + Cost effective Intake design
Concrete Volute Pumps + Cost effective Intake design
(OP)
Hi,
Is Concrete Volute Pump better in terms of cost of civil works required to install it? Is its pumping station structure smaller in dimensions and specially depth?
Somebody told me that it is more cost effective than line shaft VT pumps.
On the other hand, I need some suggestions to make me avoid constructing costly seawater pumping station. I will be happy if there is a design doesn't need breakwater. The sea water pumping station is of 100,000 m3/hr capacity. It can be expanded to 400,000 m3/hr in the future.
I am not consultant or design engineer, I am end user or developer to be more accurate.
Kindly give some guidance in this regard.
Thank you in advance

The concrete volute pump is probably more cost effective than a line shaft VT pump, byt has an upper limit on the discharge head.

You should be looking into the use of an intake system with multiple intake pipes. No breakwater is necessary. Use underground piping connected to risers out in the ocean. See the linked paper.

You have to protect the pumps from waves and assure smooth flow at the intakes.

What delivery head? how many pumps
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

I don't think you can safely extrapolate a design solution which works well in the shallow and relatively calm waters of the Gulf to, say, the UK which is exposed to the North Atlantic in the west and to the North Sea in the east. The shattered remains of numerous marine structures around this coast bears testament to the violence of the seas around our coast.

The OP is from Oman, not the UK.

Thanks - hadn't picked up on that.

Yes. The location in Oman.

We will have forebay in all cases. However, I liked your comment about protection against waves.
Is there any cheap way to control waves and avoid disturbing flow in the pumping station?
Making breakwater is costly.
