Metering Pump OBL MB31 is a 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.
Metering pump OBL MB31 has high quality and simple design of the diaphragm, these pumps are easy handling.
General Features :
- 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 (patended) mechanical diaphragm design ensures linearity between flow rate and percentage of stroke. The flow rates 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
- Maximum suction lift 1.5 m.w.c
