can anyone recommend on th pump that can be able to pump MR fluids

RE: Pump selection

what is MR fluids in your world?

RE: Pump selection

Senzomkhize,
MR is MagnetoRheological fluid?
Is it an industrial application, laboratory or research service?
If you have differents rheograms vs magnetic field intensity
and you  have magnetic field intensity in your service and
evaluated shear stress is below 100 Pa, you should use centrifugal pump, if it is higher you should use positive displacement pump.
Since MR is a Non-Newtonian fluid, you should take care in calculation loss of pressure, corrections pump factors, etc., and take in mind that conventional correlations of fluids does not apply on this kind of fluid.

I Hope Its Helps

 

RE: Pump selection

I think this definition is more clear: Magnetorheological (MR) fluids are suspensions of magnetically polarizable particles in a carrier liquid. The consistency of MR fluids shows drastic, fast and reversible changes in strong magnetic fields. Such materials are thus the ideal basis for adaptive vibration damping.

O.k. What pump? That depends upon flow and expected pressure. But gear pumps, peristaltic pumps or progressive cavity pumps seem to be options.
