Diaphragm, economical,robust, compact
metering pump.
● The mechanical diaphragm works
both giving the swept volume, acting
basically as plunger, and as separator
between casing and the pumped 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 stressproof
diapragm.
● High working safety:
- No external moving parts.
- Leak-free operations.
● Max suction lift 1,5 m.w.c. (see operating
manual).
● PTFE coated cast iron diaphragm
chamber ensures chemical compatibility
with any dosed liquid.
● Leak-free diaphragm pump head.
● Smooth and linear adjustment, either
stationary or running, via micrometer
knob.
● ± 2% accuracy within
10 to 100% of the nominal
flow rate.
