The OBL MB series are mechanical diaphragm pumps with spring return mechanism, eccentric shaft and thrust ring. They combine the working characteristics of a plunger pump with the sealing advantages of a diaphragm pump. Thanks to the quality and simple-design of the diaphragm, these pumps are easy-handling.
GENERAL FEATURES SMETALLIC SUPPORT PFTE NYLON NET RUBBER RUBBER SECTIONAL VIEW DIAPHRAGM SECTIONAL VIEW Flow rates: • 155 L/h Strokes: • 2 mm. 4 mm. • Diaphragm, economic,robust, compact metering pump. • The mechanical diaphragm works, both giving the swept volume, acting basically as plunger, and as separator between crank gear and the handled fluid. • Easy and minimum maintenance required, thanks to the reduced number of components. • The OBL’s unique (patented) mechanical diaphragm design ensures linearity between flow rate and percentage of stroke. The flow rate is virtually uneffected by the working pressure variations. • Leak-free pump, due to OBL’s stress-proof diaphragm. • High working safety:
- No external moving parts.
- Leak-free operations. • Max suction lift 1,5 m.w.c. (see operating manual).
