Thanks for responses.
Pump suction side will be directly connected to storage tank with full flow, however, at the end of each batch air will pass through the pump.
Reg shear rate, we did viscosity vs shear rate test on number of fluids yesterday. Viscosity goes down as we increase shear rate...
I want to use Lobe pump for transfer of personal care products from storage tank to filler. The pump design data would be 20 to 25 GPM at 120 to 150 psi.We are concerned about product aeration and bleeding air when we get air pockets. How lobe pump tolerate dry operation and how it affects...
BI,
"Then flow rates will increase while pressure continues to drop" is it the case for non-newtonian fluids?
I'm trying to get more data for fluid, but it's not easy. How can I experiment that the fluid is newtonian or non-newtonian or even in some conditions it shows non-newtonian behavior...
LittleInch and BigInch,
Thanks for your responses, here are more details:
- Shampoo is to be pumped from 10,000 lit tank- h=3m. (6000 CP at 25 deg C and 9500 at 22)
- 2" pressure hose of 25 ft transfers product to pump. Air at pomp is in the range of 90-100 psi
- Another 2" hose+solid SS...
Hi Latexman,
The link is taking me to Google search. Is there any particular website you were referring me to?
Please send me links to calculation pages.
Thanks,
Hi,
In our shampoo/conditioners plant, we use diaphragm pumps for transferring products from tanks to fillers. Products are in the range of 5000 to 10000 CP viscosity.(depending on temperature)We use 2" food grade pressure hose/pipe for pumping. I guess we are dealing with Newtonian fluids only...
