Fumes are exhausted into thesurrounding environment. When pumpinghazardous or toxic materials, theexhaust air must be piped to anappropriate area for safe disposal. Seeillustration #1 at right.This pump can be submerged if thepump materials of construction arecompatible with the liquid being pumped.The air exhaust must be piped abovethe liquid level. See illustration #2 atright. Piping used for the air exhaust mustnot be smaller than 1/2" (1.27 cm)diameter. Reducing the pipe size willrestrict air flow and reduce pumpperformance. When the pumped productsource is at a higher level than the pump(flooded suction condition), pipe theexhaust higher than the product sourceto prevent siphoning spills. Seeillustration #3 at right.CONVERTING THE PUMP FORPIPING THE EXHAUST AIRThe following steps are necessary toconvert the pump to pipe the exhaustair away from the pump.Use a Phillips screwdriver to removethe four self-tapping screws (item 1-H).Remove the muffler cap and muffler(items 1-G and 1-F). The 3/8" NPTmolded threads in the air distributionvalve body (item 1-A).Piping or hose may now be installed.IMPORTANT INSTALLATION NOTE:The manufacturer recommends installinga conductive flexible hose or connectionbetween the pump and any rigid plumbing.This reduces stresses on the moldedplastic threads of the air exhaust port.Failure to do so may result in damage tothe air distribution valve body.Any piping or hose connected to thepump’s air exhaust por t must beconductive and physically supported.Failure to support these connectionscould also result in damage to the airdistribution valve body.CONVERTED EXHAUST ILLUSTRATIONIllustration #1Illustration #2Illustration #3Exhaust Conversion Drawing½"½"½"On ATEX compliant units the pumpcomes equipped with a metal mufflerAir Valve Assembly |
