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, the reduced number of components.

Product Description

Mechanically actuated diaphragms which offer a chemically resistant seal-less option for low pressure applications. 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.
