PGIX2 是阿托斯双联内啮合定量齿轮泵，由两台PGI（铸铁）/PGIL（铝合金）内啮合泵组合而成，单根轴驱动、共用吸油口、两路独立压力出油口，多用于SSP伺服系统，可实现双回路独立压力流量控制，低脉动、低噪音、带径向+轴向间隙补偿。
压力规则：
双联均为PGI铸铁单元：最高连续压力跟随对应PGI单元（280330bar，峰值330350bar）
双联均为PGIL铝单元：连续250bar，峰值270bar
PGI+PGIL混合组合：整泵压力上限取较低的PGIL侧250bar 介质：矿物液压油ISO VG10~100 mm²/s；标准NBR密封，后缀PE=FKM氟胶密封 型号编码示例：PGIX2-2032/1011/1DPGIX2=双联内啮合泵｜2032=前泵单元（Size2，32cc）｜1011=后泵单元（Size1，11cc）｜1=平键轴｜D=顺时针转向；R=反向旋转

备注说明：
PGIX2：双PGI铸铁高压双联；PGIX2L：双PGIL铝合金轻量化双联；PGIX2M：PGI+PGIL混合双联；
两路出油相互独立，可分别用于主回路+控制/保压/润滑回路，是SSP伺服液压站非常常用方案；
双联泵不能两个单元都超最高转速，转速按排量更大单元的转速上限来选取。
