概述
BL系列单级单吸悬臂式直连离心泵，供输送清水及物理化学性质类似于水的液体。此型泵是在BA型泵基础上对结构进行改进，具有外形小，重量轻，结构简单和装卸方便等特点。其性能参数与BA泵相同。
本型泵（50Hz）扬程在9—62米时范围内，流量为4.5—120立方米/时范围内，液体的最高温度不超过85℃为填料密封；液体的最高温度不超过100℃为机械密封。我公司生产的BL型船用直连离心泵的叶轮用硅黄铜、泵轴用不锈钢制成，适用于船舶抽送舱底水、主辅机冷却水、消防等，介质为淡水或海水。
型号说明： 2BL 1-6A
2—吸入口径被25除的整数值（即该泵吸入水口径为50毫米）
BL—单级单吸悬臂式直连离心泵
1—电源为60Hz，50Hz时不带“1”
6—比转数被10除（即该泵的比转数为60）
A—表示叶轮直径车小后的一种规格
