Operates on as little as bar ( MPa)air pressure Easy-to-service air valve & ball checks Quiet operation 75 dBa at bar ( MPa) and 60 cpmFirst choice whenquality counts. RForm No. 305-712 ETypical FluidsHandled Paints Lubricants Inks Stains Solvents Coatings DyesEconomical 3/8" Diaphragm PumpGraco s husky 307 Diaphragm pump is designed tooperate at low air pressure while delivering a smooth,reliable flow. husky 307 pumps are ideal for transferring a wide variety of fluids. Two models are offered: Acetal wetted construction suitable for water-, solvent-and petroleum-based fluids, with either Teflon or Hytrel diaphragms and ball checks.

2 Polypropylene wetted construction for most acidsand caustic fluids, with either Teflon or Hytreldiaphragms and ball Air Valve DesignThe husky 307 features Graco s new patented air valvedesign with the following advantages: Simplified design (only 15 parts) improves reliabilityand serviceability air valve is accessed by removingonly six screws and there are no pilot valves. Lubricated air is not required. Air valve uses compressed air very efficiently, for loweroperating cost. Air valve will operate on as little as bar ( MPa).This allows the pump to cycle at low flow rates,producing a gentle pumping action ideal for shear-sensitive fluids and for spraying coatings. Reset button offers convenient re-starting undertough service Applications Drum transfer for fluids up to 1000 centipoise Circulation of low viscosity inks, stains and dyes Coolant circulation and evacuation Waste fluid removal On-demand batch chemical metering Low viscosity adhesive supply Consistent low pressure air spray or HVLP supplyAcetal ModelPolypropylene Model(with Teflon Diaphragm and Ball Checks)Viscosity Correction Curve(with Hytrel Diaphragm and Ball Checks)How to read the performance chartsTo determine the fluid pressure: Locate the desired fluid flowonthe horizontal axis, and read up to the appropriate incoming airpressurecurve.

3 From that intersection, read across to find the determine the fluid flow:Locate the desired fluid pressureonthe vertical axis, and read across to the appropriate incoming airpressurecurve. From that intersection, read down to thehorizontal axis to find the maximum fluid determine the air consumption:Find the intersection of thefluid pressureon the vertical axis and the appropriate incoming airpressurecurve. Locate the nearest air consumptionline tointerpolate the air Example (See *on Performance Chart):For fluid pressure of bar ( MPa) at bar ( MPa) incoming airpressure, the maximum fluid flow is lpm and air consumption is 3 scfm( m3/min). husky 307 PerformanceHow to read the viscosity correction chartTo determine the maximum flow rate for any viscosity:On thehorizontal axis, find the viscosity of the fluid.

4 Move straight up tothe intersection of the curve. From that point, read across to themaximum flow on the vertical adjust the performance chart for higher viscosity fluids:(Theperformance charts are based on the viscosity of water, 1 centipoise).First determine (A) the fluid flow for water using the PerformanceChart. Then find (B) the maximum flow using the ViscosityCorrection Chart. Next, choose (C) the maximum rated flow for the pump:Hytrel l/Min. Teflon diaphragms l/Min. The adjusted flow rate of the higher viscosity fluid is equal to:A x B/CFor example: A Teflon Diaphragm pump operates at bar ( MPa) fluidpressure at bar ( MPa) incoming air pressure. What is the adjustedflow rate for a fluid with a viscosity of 600 centipoise?
