KREBS® centrifugal slurry pumps

Mechanical grinding of these solids consumes power and wears the impeller and the suction liner As these parts wear, the suction-side gap grows and the slurry is free to recirculate back to the impeller eye This reduces the flow, head and efficiency of the pump...

Slurry Densities

ρ l = density of liquid without solids (lb/ft 3, kg/m 3) Slurry concentration by weight can be measured by evaporating a known weight of slurry - and measure the weight of dried solids Example - Calculating Slurry Density The density of a slurry where the density of the solids is 2500 kg/m 3; the density of the liquid is 1000 kg/m 3...

Flash flotation equipment design

Mill grinding efficiency is strongly proportional to the mill feed density As such, the mill feed density is normally kept as high as practicable As the top outlet removes a large portion of the flash feed dilution water, the bottom outlet slurry density is maximised, which is beneficial for maintaining grinding efficiency...

Pump Capacity Variation With Density

Mar 19, 2012· Pump Capacity Variation With Density - posted in Industrial Professionals: Hi If a pump is selected for 100 m3/hr at a given mass density of a fluid, will the pumping capacity of the pump change with variations in density due to temperature? My understanding is that centrifugal pumps are volumetric machinery and hence, they work at a fixed volumetric flow even if there are density ,...
