Pump Technology

I'm not necessary a pump engineer, I would say that a "pump engineer" would be someone that firstly design pumps, and be someone that works on pumps. However, I have been designing systems for the last 18 years with pumps. In other words, a client would like to transfer water from a water source like underground water, dam water or from a stream or river. It is my job to firstly calculate the amount of water the client needs to transfer, survey the intended pipeline if it is very long and then do a string of calculations to see if the source will safely keep up with the demand, or that the new pipeline is adequately sized to minimize friction and velocity. Then once this and some more are established then I would look at the pump size to be used. Further to that I would work out what the pump will absorb in terms of power needed at start up etc. Then I will size the electric motor, or diesel engine to drive the pump.

The nice thing about working in this type of industry is that not any of the applications are the same, so it's a challenge every time I need to work out the pump requirements. To answer you on would I recommend this type of job to someone, yes I would, but you would need a very good understanding about hydraulics. I mainly deal with water pumps ranging from 0,1 litters per second to 5000 litters per second.

I m Mechanical Engineer

at which I work a problem of air barrel pump indent, following specified pump is install in our company 25 years ago and now this model is not manufactured by garco company, we purchase an alternative pump but could not operate due high viscosity oil.

Specification:

Company: Graco

Type: 203 T 204

Model: 060-001-30324.

Lubricant used Gardium Compound EP 100 of Shell Company.

Air pressure more than 4kg/cm².

Lubricant amount 87 Cm³/H.

Temp: 9 to 60 ⁰C

Power source 50Hz, 220 volts

Dear if u have any solution to purchase above pump or equivalant to above pump please tel me

dear sir

please tell me suitable pump for condensate transfer application. if possible explain me how to calculate in such condition considering another fluied or vicous material like soap, oil. deatils of condensate line as follows:

boiler capacity-10 tonnes (2 boilers so 20 tonnes)

total pipe length-60mtrs

no.of bends-6

valves-2

height-15 mtrs

please tell me what specifications i have to decide and how i suppose to calulate for different applications.i will be very much thankfull.

Hi,

I work as a specialist consultant to Airbus on the implementation of pumps into fuel systems. We have some unique challenges in particular implementing pumps that must be designed to operate under cavitating conditions in normal operation.

We've had further challenges with the form of power available to us. The shift from fixed frequency supply to variable frequency has driven different technology into the pumps, for example Brushless DC and high slip AC motors.

The latest challenge we have is to implement a constant pressure pump that adjusts it's speed to match a constantly changing absolute outlet pressure.

So, I would certainly recommend a career in aerospace pumps to my siblings, but I would warn them not to expect an easy life!

I am not a pump engineer, but I am a rotating machinery engineer. I work for a large international oil company and as a rotating machinery engineer I might be involved with a compressor one day, a gas turbine the next, and a large pump after that.

We use very small pumps to very large pumps, but for the most part I get involved with pumps when they are large, very high speed, or just very critical. Waterflood injection pumps and electric submersible pumps are an example of that, as are boiler feed pumps.

I was practicing as a 'rotating equipment engineer' for over 25 years. Seen lots of incidents which challenged and found pleasure in meeting most of them. But still many stay as mystery in mind awaiting for answers.

Later part of my employment was mostly towards training. Fascinated by the experience of importing and sharing the knowledge to the needy youngsters, I wanted to enhance the training process in ways people would enjoy learning. Towards this mission, I now in Computer Based Training modules developments. Doing so I realise, what all I thought that I knew are still not adequate. This is one of the reasons I'm in CR4 and still learning from many people like Steve, bwire, ozzb, techno, Del the cat, RHABE, Ace Boeringa, jmart23, caramba and manay more. After all sharing our experience in such a great forum is mutual learning too.
