“AT-3”系列仅配备***法兰。齿轮端盖的设计允许使用2-1/2英寸的美国标准管尺寸，和2英寸的法兰边。目前有三种不同类型：带螺纹的，碰焊，承插焊接。所有AT-3泵特别适合车载应用，或法兰连接是必要的。如果端口作为入口，通过同时提供液体到齿轮组合来减少内部障碍。有两种基本的结构包括”L”型和”R”型。”AT-3R”和”AT-3L”有相同端口，反方向进入，如下图所示。”H”和”Non-H”型之间更多的区别为：在相同速度时，带着字母”H”型号的有更高的输出功率。在***大速度时，这些泵的压差性至少为300PSID，液体粘度大约为500SSU。它们的设计是为水平底座装备的，能直接驱动马达，或使用齿轮减压器，驱动传动带，驱动链条。旁通阀和过滤器是被推荐的另外装备。***ith液态输送泵ATC-3LHSPECIFICDATA:”AT-3Series”pumps,to100G.P.M.,ratedoutput.AT-3R:Right-handedrotationforinletthroughgearendcover,packinggland,reversible,vacuumcapability,***ithflangesprovidedinthreedifferentstyles,2-1/2inchcoverportand2inchmainhousingports,blindflangeprovidedforunused,mainhousingport.AT-3RH:Right-handedrotationforinletthroughgearendcover,packinggland,vacuumcapability,***ithflanges,ATC-2R:Right-handedrotationforinletthroughgearendcover,rotaryormechanicalseal,reversible,vacuumcapability,***ithflanges.ATC-3RH:Right-handedrotationforinletthroughgearendcover,rotaryormechanicalseal,reversible,vacuumcapability,***ithflanges,higheroutputatsamespeeds,samedimensi***.AT-3L:Left-handedrotationforinletthroughgearendcover,packinggland,reversible,vacuumcapability,***ithflangesprovidedinthreedifferentstyles,2-1/2inchcoverportand2inchmainhousingports,blindflangeprovidedforunused,mainhousingport.AT-3LH:Left-handedrotationforinletthroughgearendcover,packinggland,reversible,vacuumcapability,,***ithflanges,higheroutputatsamespeeds,samedimensi***.ATC-3L:Left-handedrotationforinletthroughgearendcover,rotaryormechanicalseal,reversible,vacuumcapability,***ithflanges.ATC-3LH:Left-handedrotationforinletthroughgearendcover,rotaryormechanicalseal,reversible,vacuumcapability,***ithflanges,higheroutputatsamespeeds,samedimensi***.)
