I NTE R NAL G EAR P U M PSTopGear2 03/2012 SB-J P-TG-E NBased in Charlotte, North Carolina, SPX Corporation (NYSE: SPW) is a global Fortune 500 multi-industry manufacturing leader. For more information, please visit www.spx.comGear pumps are used in all types of manufacturing industries for the transportation of both thin and thick liquids, from diesel fuels to chocolate. The Johnson Pump brand heavy duty pumps are designed around high reliability as well as long life. TopGear offers a combination of strong design with small or large clearances, unique gear tooth profile and options such as electrical heating and built-on safety relief valves.The extensive TopGear series is divided into three ranges; the TG G-range for general purposes, the TG H-range for high demanding applications and the TG L-range that offers high efficiency when transporting low viscosity fluids. For applications demanding leak-free operation a magnetically driven, TG MAG, is available.TopGear When reliability is the priorityTG G & TG H rangesI M PROVE D PR I M I NG, LOW N PS H R• Ports above centerline• Oversized ports for better efficencyI M PROVE D D E S IG N FOR LOW AN D H IG H VI SCOUS M E D IA• Optimized gear tooth profile• Smooth flowH IG H E FFICI E NCY• Axial rotor locking• Adjustable clearances• Balanced hydraulic designE LI M I NATE D LEAKAG E D U R I NG TH E R MAL EXPAN S ION• Pin cover• Safety sealedS EVE RAL MATE R IAL OPTION S• Shaft seal materials• Bearing materials• Hydraulic partsPROLONG E D S E RVICE LI FE• Double ball bearing design• Adjustable axial clearance• Allows V-belt drive• Accepts higher axial forcesM I N I M U M OF MAI NTE NANCE• Cartridge design• Simple designMAXI M I Z E D LI FETI M E• Compact rotor• Strong shafts• Maximized bearing design• Possibility for selection of hardmetal bearings• On seals thanks to seal relief channelLE SS DOWNTI M E• Front and back pull-outFLANG E CON N ECTION S OPTION S• EN• ANSI3 03/2012 SB-J P-TG-E NTypical product applicationsTECH N ICAL DATATopGear pumps are used in various industries and environments, which have thousands of liquids that need to be pumped.PetrochemicalsPure or filled bitumen, pitch, diesel oil, crude oil, lube oilchemicalsSodium silicate, acids, plastics, mixed chemicals, isocyanatesPaint and inkResins and adhesivesPulP & PaPeRAcid, soap, lye, black liquor, kaolin, lime, latex, sludgeFoodChocolate, cacao butter, fillers, sugar, vegetable fats and oils, molasses, animal feedsOPE RATI NG PR I NCI PLEAs the rotor and idler unmesh, an under-pressure is created and the liquid enters the newly created cavities.Liquid is transported in sealed pockets to the discharge side.

Magnetic drive available as the TG MAG.JACKET OPTION SHeating and cooling jackets guarantee the performance of the pump in a start-up or a shut-down procedure. They also provide the pump with the best condition for the seals during operation. Different options: thermal oil, steam or electrical heating.SAFETY R E LI E F VALVE OPTION SBuilt-on safety relief valves protect the pump, as well as other equipment in the system, from over pressure. When the pump is used bi-directionally, a double safety relief valve is available.
