Flygt slurry pumpsCalculation effects of slurry1. Determine SG/density of the liquid. If the density is unknown,it can be determined by using the formula or nomograph;Cw/Cv S/SmS Specific gravity (SG) of dry solidsSm SG of the slurryCv Concentration of solids by volumeCw Concentration of solids by weightMax Cv for centrifugal pumps is 40%2. Calculate the critical velocity. Choose a pipe diameter so thatthe pipe velocity is higher than the critical velocity.1. Water coarse gravel 4 m/s2. Water gravel 3 m/s3. Water sandParticles 0.1 mm 1.5 m/sParticles 0.6 mm 2.5 m/s(Pipe velocity V Q/A [A pipe area])4840Solids by volume, CV3. Calculate the total discharge head.Use diagram or formula on page 86(Friction loss chart in Pumps 101 section).If the concentration is more than 15% byvolume (CV), the value should be adjustedusing the correction factor (Cf) diagram.Cf for slurry CV 30% 1.53020101.01.21.5Factor de corrección, Cf1.8

4. The required duty point has now been established (Htotal). If thesolid concentration exceeds 15% by volume, the discharge head of thepump must be reduced. By dividing the duty head with the reductionfactor (HR), the equivalent clean-water pump head is obtained (Hcv).0300 200150 100 72 52 3625 18 141075Solids SG1.50.041.750.1Factor K2.02.5Head Reduction:CvHR 1 – K 2030 1 – 0.04 20HtotalHcv HR3.03.50.24.05.0Diagram forreduction factorHR0.6 0.8 0.9.2.48.0.61246d85Htotal Head total slurryHfrsl Friction losses forslurryHfrcw Friction lossesClean WaterHfrsl Hfrcw CfHtotsl Hstat HfrslExample S 1.8. d85 1 mm.

The power curves for the pumps are based on clean water andthese must then be multiplied by the specific gravity of the slurry toobtain the corresponding value for slurry pumping. Flygt recommendsa motor with a 20% excess power margin for slurry applications dueto variations in slurry.49
