AY型油泵分两种结构形式： 单级单吸悬臂式、两级单吸悬臂式、单级双吸悬臂式、单级双吸两支承式、两级单吸两支承式。 该型泵壳体为径向剖分，安装方式为水平中心线支承，泵的吸入口和排除法兰为垂直向上，轴封不仅能用软填料，而且与机械密封互换。轴承体装有一套向心球轴承和一组背对背安装的推力球轴承，轴承用稀油润滑，为了检修方便，不必拆卸吸入或排出管路、采用了弹性柱销加长联轴器（也可配弹性膜片联轴器）就能很容易地拆出叶轮，轴承、轴承等零部件。
概述
◇ AY系列离心油泵是在老Y型油泵的基础上进行改造并重新设计的
◇ 轴承部件将原35、50、60轴承体分别用45、55、70轴承体，提高了可靠性。
◇ 水力过流部位采用了高效节能泵的水力模型，平均比老Y型油泵的效率高出5~8%。
◇ 为保持继承性，AY型系列油泵的结构形式、外形安装尺寸、性能参数范围保持与老Y型系列油泵相同，便于老装置更新改造。
◇ 零部件通用化程度高，通用标准件为几个规格产品公用。
◇ 选材精练，主体以Ⅱ、Ⅲ类材料为主，轴承体等零件增加为铸钢、铸铁两种，为寒冷地区露天使用、船用提供了有利条件。
◇ 轴承有空气冷、风扇冷、水冷三种，根据泵的不同使用温度选用。其中风扇冷尤为适用缺水或水质差的地区。
◇ 从电动机端看为逆时针方向旋转
◇ 执行标准 GB3215-82和AP1610（OH2）
●参数范围
◇ 流量 2.5~600m3/h
◇ 扬程 30~330m
◇ 温度 -45~+420℃
●适用范围
主要适用于输送清洁的、低温或高温、中性或腐蚀性液体。
主要应用于石油精制、石油化工、化学工业、油田、油气输送等领域。
