40descriptiOn Of unit PS 3.29 / 3.313 deScRIPTIoN oF uNIT3.1 AIRLeSS PRoceSSThe main areas of application are thick layers of highly viscouscoating material for large areas and a high consumption ofmaterial.A piston pump takes in the coating material by suction andconveys it to the tip. Pressed through the tip at a pressure ofup to a maximum of 221 bar (22.1 MPa), the coating materialis atomised. This high pressure has the effect of micro fineatomisation of the coating material.As no air is used in this process, it is described as an AIRLESSprocess.This method of spraying has the advantages of finestatomisation, cloudless operation and a smooth, bubble-freesurface. As well as these, the advantages of the speed of workand convenience must be mentioned.3.2 FuNcTIoNING oF THe uNITIn the following there is a short description of the technicalconstruction for better understanding of the function.Wagner PS 3.29 / 3.31 units are electrically driven high-pressurespraying units.A gear unit transfers the driving force to a crankshaft. Thecrankshaft moves the pistons of the material feed pump up anddown.The inlet valve is opened automatically by the upwardsmovement of the piston. The outlet valve is opened when thepiston moves downward.The coating material flows under high pressure through thehigh-pressure hose to the spray gun. When the coating materialexits from the tip it atomizes.The pressure control knob controls the volume and theoperating pressure of the coating material.3.3 TecHNIcAL dATAPS 3.29 PS 3.31Voltage220~240 VAC, 50/60Hz220~240 VAC, 50/60Hzmax. current consumption7.5 A 8 APower cord3 x 1.5 mm2 – 6 m 3 x 1.5 mm2 – 6 mAcceptance capacity1725 Watt 1840 Wattmax. operating pressure221 bar (22.1 MPa) 221 bar (22.1 MPa)Volume flow at 12 mPa (120 bar) with water3.0 l/min 3.8 l/minmax tip size0.029 inch – 0.73 mm 0.032 inch – 0.81 mmmax. temperature of the coating material43°C 43°Cmax viscosity25.000 MPa·s 25.000 MPa·sWeight43.5 kg 43.5 kgSpecial high-pressure hoseDN 6 mm, 15 m,connection thread M16 x 1.5DN 6 mm, 15 m,connection thread M16 x 1.5dimensions (L x W x H)590 x 529 x 726 mm 590 x 529 x 726 mmAltitudeThis equipment willoperate correctlyup to 2000 m abovemean sea levelThis equipment willoperate correctlyup to 2000 m abovemean sea levelVibrationSpray gun does notexceed 2.5m/s2Spray gun does notexceed 2.5m/s2max sound pressure level80 dB* 80 dB** Place of measurement: 1 m distance from unit and1.60m above floor, 12 MPa (120 bar) operating pressure,reverberant floor
