Mechanically, the AUS-V Series pumps are basically very similar to the ones of the jolly Series.
Their distinguishing feature is the special design of the casings-impeller assembly, which allows them to operate even without liquid. Moreover, the only maintenance required is the greasing of the bearings.
The result is a pump that can work under the severest conditions: in wells with poor access, where flow is intermittent, or where level controls or flow switches cannot be installed. In all such cases the pump is merely left running continuously and will handle liquid as it reaches the well. If the flow stops, the pump continues to run dry without damage, and when the liquid reaches again the well the pump primes itself automatically.
