Uptime & Maintenance Engineer

11/28/2007 1:23 AM

to our CR4 Engineering Community

Deal All,

Our plant is producing metallic and paint coating, there ara lot of diagpraghm pump used to transfer fluid (paint & chemical). Using diagpragm type is unreliable, lot of pump problems, Currently we are seeking for other pump type to replace the diagpragm one to get optimum life time.

We plan to change the pump to other type, does anyone can help me to choose what is the best pump for our application?

regards,

Amanu

Look at gear pumps.

BIG peristaltics may do the job...but the tubes will still wear and need periodic changing, they are generally more reliable than diaphragm pumps and have a big advantage over some pumps in that there is no contact between the pump parts and the fluid being pumped.

Definitely my first choice for this application would be a peristaltic pump. The metalic paints could be an issue depending on particle size of the pigments.

Another possibility is the 'Mono' pump,which is a progressive cavity type with rubber or other elastomer stator and s/s or other metal rotor.these can pump half bricks, (okay, I exagerrate) at fairly high pressures,say 10 bar,and can be series conn'd for more pressure.Google 'Mono' for more info.I was introduced to these by a paint manufacturer.
