1SP A, SPGeneral descriptionApplicationsThe SP A and SP pumps are suitable for the followingapplications:• raw-water supply• irrigation• groundwater lowering• pressure boosting• fountain applications• mining applications• off-shore applications.Type keyExample SP 95 - 5 - A B NType range (SP A, SP)Rated flow rate in m 3 /hNumber of impellersFirst reduced-diameter impeller (A, B or C)Second reduced-diameter impeller (A, B or C)Stainless-steel parts of material= EN 1.4301N = EN 1.4401R = EN 1.4539Pumped liquidsClean, thin, non-aggressive liquids without solidparticles or fibres.The special SP A-N and SP-N versions made ofstainless steel to EN 1.4401 and SP A-R and SP-Rversions made of stainless steel to EN 1.4539 areavailable for applications involving aggressive liquids.Operating conditionsMaximum liquid temperatureGrundfos motorFlow velocitypast motor[m/s]Max. liquidtemperature[°C]MS 4" 0.15 40MS 6000 0.15 30MS 4" industrial versions 0.15 60MS 6000 industrial versions 0.15 60MMS 6" with PVC in the0.15 25windings0.50 30MMS 6" with PE/PA in the 0.15 45windings0.50 50MMS 8", 10", 12" rewindable 0.15 25with PVC in the windings0.50 30MMS 8", 10", 12" rewindable 0.15 40with PE/PA in the windings 0.50 45Operating pressureGrundfos motorMS 402MS 4000 and 6"MMS 6", 8", 10", 12" rewindableCurve conditionsMaximum operating pressure1.5 MPa (15 bar)6 MPa (60 bar)The conditions below apply to the curves on pages 14to 70.General conditions• Curve tolerances according to ISO 9906, 2012Grade 3B.• The performance curves show pump performanceat actual speed, cf. standard motor range.Approximate motor speeds:4" motors: n = 2870 min -16" motors: n = 2870 min -18" to 12" motors: n = 2900 min -1 .• The measurements were made with airless water ata temperature of 20 °C. The curves apply to akinematic viscosity of 1 mm 2 /s (1 cSt). Whenpumping liquids with a density higher than that ofwater, use motors with correspondingly higheroutputs.• The bold curves indicate the recommendedperformance range.• The performance curves are inclusive of possiblelosses such as non-return valve loss.SP A, SP curves• Q/H: The curves are inclusive of valve and inletlosses at the actual speed.Operation without non-return valve will increase theactual head at rated performance by 0.5 to 1.0 m.• NPSH: The curve is inclusive of pressure loss in thesuction interconnector and shows required inletpressure.• Power curve: P2 shows the pump power input ofeach stage for the individual pump size when thepump is running at the rated speed.• Efficiency curve: Eta shows pump stage efficiency.If Eta for the actual pump size is needed, pleaseconsult www.grundfos.com (WebCAPS).Note: For MMS 6", 37 kW, MMS 8", 110 kW, and MMS 10", 170 kW,the maximum liquid temperature is 5 °C lower than the values stated inthe table above. For MMS 10", 190 kW, the temperature is 10 °C lower.4
