Metering Pump OBL MB11


Metering Pump OBL MB11 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.

Features Metering Pump OBL MB11 :

  • 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 )
