Dear sir or madam: i want to know that is it possible to use cast material for coupling gaurd of pumps?

Depends\nI would say a a cast ductile iron piece would work on a small pump and motor assembly .  How ever more info is needed. Knowing the motor Horse power and shaft length. Mainly you are covering the shaft so accidental contact can't be  made by a person,,, But if you are needing it to also protect against flying object if the shaft breaks,,then thats going to change a few things

If it's just a school project, you might try pumping it or simply use a bucket. It depends on how large your model and pocket are.\nIn actual aqueducts, the water is already at a higher level (like a mountain spring or lake) so I think it would be fair to replicate that situation.

That's a bit too long of an answer for this type of medium... however, here's a link to a PDF with diagrams and such that can answer your question.

Check out this site for the complete story:\nhttp://yarchive.net/metal/ball_bearing_manufacture.html\nRemember, all I did was google "ball bearing manufacture"\nYou could learn to do that yourself!

Are you refering to welded tube or seamless tube? If there is something specific that you are looking for, ask a specific question.\n\nhttp://www.corusgroup.com/en/products/tube_products/cold_form/\n\nhttp://www.tatatubes.com/facts.htm\n\nhttp://www.mstube.com/

It is all relevant to what type of molding? Depending on the medium used and how difficult it is....setting up the inserts before is preferred for QC/QA reasons but drilling in later can be even better if the labor is not extreme.

You basically need information on metal manufacturing, casting, and molding.  Not really something that can be done at home.

Here is a link to a stirling engine design that uses hydraulic fluid to couple its pistons to the shaft.  It may not be the answer to your question, but it is interesting.

I assume the pump performance curve is unavailable, pity. You know what the current rpms, pressure and power is. I would apply the pump affinity laws in order to determine what the increase in rpm(flow) and power it will take to make the pressure you require. It may be  easier getting a bigger motor for the existing pump, than going through the time and effort of a single new pump, pumps in series, piping reconfiguration etc, all of which will work.

If you are thinking about welding ... forget it! Cast iron does not weld. A highly skilled person can braze cast iron together but the high heat can distort the iron and can be expensive. And you still have the appearance of the raised braze bead to deal with if it is on an outside surface.\n\nI recommend "gluing" cast iron together. A good product to use is called J-B Weld. It is a two part epoxy adhesive that comes in small squeeze tubes. Follow directions on the package. This stuff does not make a good filler material because it is somewhat runny before it sets up.

That's not going to be an easy task.\nIt's not usually done.\n\nEbay has soldering tools, even SMT ones.

to my surprise, there appear to be many sites that sell such equipment; check it out:\nhttp://www.google.com/search?client=safari&rls=en&q=vacuum+bellow+gatan+ion+mill&ie=UTF-8&oe=UTF-8

a couple options\n1 - take it to a welding shop and have them fill them\n2 - waterproof epoxy  make sure the metal is clean and rough first.\n3 - you could use self sealing pop rivets and rubber\n4 - get a bigger bilge pump :-)

it can be done. You will need a special adaptor,

I don't think it is a good idea due to the compresser.  You could ask someone like at a Lowe's or Home depot store but, I really don't think you are supposed to.
