力士乐外啮合齿轮泵，包括：四个系列 (B、F、N 和 G) 的标准齿轮泵，以及三个系列 (S、T 和 U) 的静音齿轮泵；其中，排量按不同的齿宽进行分级。通过法兰、轴和阀的不同布置、以及多级泵的各种组合方式，还可得到其它配置变型。
外啮合齿轮泵，主要由轴承衬套上支承的一对齿轮、以及配备前盖和后盖的泵壳组成。传动轴从泵的前盖向外伸出，并通过轴密封圈加以密封。轴承上的这些支承力，则由的轴承衬套所吸收；由于滑动轴承具有足够的弹性力，因而形成了面接触、而不是线接触的方式。由于这样，因而还确保了泵的耐磨性 - 尤其是在低速运行时。这对齿轮分别有12个齿，从而可保持齿轮泵产生限度的流量脉动和噪音。
内部密封是通过补偿力实现的，这些力与输出压力成正比。利用这种补偿方式，就能确保实现的效率。这些轴承为间隙 (也即介于输送高压油液的轮齿之间) 的末端提供密封功能。通过对轴承的后部输入工作压力，就可以控制介于轮齿与轴承之间的密封区域。这些密封件，构成了这一区域的边界。对于轮齿部的这些径向间隙，则通过将齿轮推向泵壳的内部作用力而实现密封。

齿轮泵是液压泵中结构简单的一种泵，它的抗污染能力强,价格便宜。但一般齿轮泵容积效率较低，轴承. 上不平衡力大，工作压力不高。齿轮泵的另一一个重要缺点是流量脉动大，运行时噪声水平较高，在高压下运行时尤为**。齿轮泵主要用于低压或噪声水平限制不严的场合。一般机械的润滑泵以及非自吸式泵的泵都采用,齿轮泵。
从结构_上看齿轮泵可分为外啮合和内啮合两类,其中以外啮合齿轮泵应用广泛。
外啮合齿轮泵工作原理
外啮合齿轮泵由一对完全相同的齿轮啮合，产生上下体积变化，这就形成了吸油区和压油区。同时在啮合过程中啮合点沿啮合线移动,把这两区分开，起配流作用。
泵的排量
泵每转一周把两个齿轮上齿谷中的存油排出。如果泵中采用标准齿轮,并取齿谷的容积等于齿部的体积，则齿轮每转一周排出的体积可近似等于外径为(mZ+2m)，内径为(mZ-2m)，厚度为B的圆环体积，即
q=π/4[(mZ+2m)2-(mZ-2m)2]B=2rm2ZB
由于齿谷的体积大于齿部，实际几何排量还要大一些，故以3.33代替上式中的π较接近实际情况。得q=6.66m2ZB即泵的实际流量为: Q=6.66m2ZBηpv'n
工作原理
液压泵是靠密封容腔容积的变化来工作的.原动机带动泵旋转时,通过一定机构使泵内的密封工作腔的容积发生变化,由配流装置使密封工作容积轮流和吸油口或压油口相通,从而使泵进行吸油和排油.
密封容积大→泵吸油 输入: 转矩和转速
密封容变小→泵压油 输出: 压力和流量
基于.上述工作原理的液压泵叫做容积式液压泵,液压传动中用到的都是容积式液压泵。
工作原理:
中当凸轮旋转时,柱塞在凸轮和弹簧4的作用下在缸体内往复运动。当柱塞右移时,密封工作腔的容积变大，产生真空，油箱中的油液在大气压力作用下通过单向阀吸入缸体内,实现泵吸油。当柱塞左移时,密封工作腔的容积变小，油液受到挤压便通过单向阀输送到系统中去，实现泵压油。如果偏心轮不断地旋转,泵就会不断地完成吸油和压油动作,因此就会连续不断地向液压系统供油
