特点： | GENERAL FEATURES |
■ 隔膜式、经济型结构紧凑的计量泵。
| ■ Diaphragm,economic,robust,compact metering pump. |
| ■ 机械隔膜工作时，既像柱塞一样的冲程排量 | ■ The mechanical diaphragm
works,both giving the swept volu-
me ,acting basically as plunger,
and as separator between crank
Gear and the handled fluid. |
■ 泵构件数量少，从而维修简单而且容易。
| ■ Easy and minimum maintenance
required,thanks to the reduced |
■ OBL独特的机械隔膜设计（已获专利），
确保了输送流量与冲程比例间的线性关系。
| ■ The OBL's unique (patented)
mechanical diaphragm design
ensures linearity between flow rate
and percentage of stroke. The
flow rate is virtually unaffected by
the working pressure variations. |
■ OBL的抗压隔膜使泵具有了无泄漏的特点。
| ■ Leak-free pump,due to OBL's stress-proof diapragm. |
■ 高度的安全工作性：
- 没有外部活动件；
- 无泄漏操作。
| ■ High working safety:
-No external moving parts
-Leak-free operations. |
| ■ 最大自吸高度：1.5m | ■ Max suction lift1,5 m.w.c.(seeoperating manual). |
