Pumps and Slurries

Tell us more about the mystery chemical slurry.

No problem, the slurry come from a silver-gold mine and are send to the tailings dam. It have 50/55 % of solids in water. But I understand that will be "pushed" in to the sump pump with water.

May be I can consider as "heavy liquid"?

Use two pumps and two waste streams designed according to their respective viscosities rather than "blending" the discrete waste streams into one.

No problems the slurry pump requirements will also handle water. We regularly flush our tailings lines with water using the pumps in the tailings line. You will need to do your calcs for the sump pump based on the heaviest liquid properties that the pump is going to handle.

Pumping water with a slurry pump may not be the most efficient use of a slurry pump so I would consider which liquid you would be pumping most of the time. If you are in a tropical area where it rains every day for 6 – 8 months I would go for two pumps one for the slurry and one for the water. Water pumps for less than 1 m³/hr should cost significantly less than a slurry pump 55 m³/hr.

The best reference material for slurry pumping that I have come across is the Weir Warman "Slurry Pumping Manual" available from the following link,

Hi ernesto1962

You should use one slurry pump to pump up both the slurry and the rainfall.First you have to know the max solid size that will pass the pump impeller, then you should select your pump based on thr following:

-Total discharge flow in cubic m/h

-Total dynamic head in m

-Max solid size in mm

Most likely you will be in need for a submersible,open impeller of vortex type.

You,also,can use a diaphragm pump or a progressive cavity pump.

In all cases you should tell the pump manufacturer about nature of slurrey that you are using.Mono pumps ,allweiler a.g.,and tsurumi pumps are a screw pump manufacturers that you can refer to.Welden pumps is a diaphragm pump manufacture.
