    Tank of slurry, sealed air intake to generate flow

    LittleInch, I tried a slight variation to your idea. Basically it does not work fast enough. A little more rustic way is that the air intake pipe is left to atmosphere and someone controls the air intake by their thump trying to maintain a constant level in the tank. Not ideal i know, but i...

    Tank of slurry, sealed air intake to generate flow

    Hi LittleInch, after thinking about your tube, wont the slurry in the main tank be slowly sucked up the tube due to the vacuum pressure in the feeder tank? I dont understand the float system design. Can you explain it a little more. Perhaps this prevents the slurry rising. Looks good though...

    Tank of slurry, sealed air intake to generate flow

    Hi Thanks for the comments. I cant move the outlet to the same level as the pressure in the primary tank as I need a pressure to maintain a higher flow rate. I like the idea of the line. I will think a little more on the pipe diameter and report back. I need a flow rate up to 2 litres a...

    Tank of slurry, sealed air intake to generate flow

    Hi, I've been driving myself around the bend with this problem and feel its a simple solution that someone can comment on. I have a flow experiment whereby i need to maintain a constant level in a tank. The problem is that the flow rate controlled by the exit value of this tank varies. I...

    Positive displacement pump - No pulsation

    Good point. There is a distributor of Moyno here who i'll chase up. Just worried about the abrasive nature of the sand slurry and how it will affect the life span of the pump. It also needs to be able to suck the thick slurry from the holding tank and not rely on gravity feeding. I will have a...

    Positive displacement pump - No pulsation

    I am based in Chile. They have all the big pump suppliers here.

    Positive displacement pump - No pulsation

    Hi, I typically use peristalitic pumps to pump thick sand slurry (60 to 75% solids weight for weight) with a yield stress of up to 120 pa. My flow rate requirements are 1 to 10 litres a second. I typically use the Bredel SPX range, which work well. However, the pulsation in the flow is not...
