Diaphragm Pump OBL MB50 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 Of Diaphragm Pump OBL MB50 :
- 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
