    WORING PRINCIPLE A pair of speciallyprofiled screw machined integral from solid stock and well supported onantifriction bearings run in precision bored interchangeable casing linersEach screw set has one right hand and one left hand screw engaging with asimilar but opposite hand screw pair A pair of hardened and profile groundtiming gears synchronize the screws to maintain a small but positive clearancebetween the flanks thus ensuring no metal to metal contact The pumps cantherefore run dry for sometime without any damage This unique feature enablesto run the pump even dry and handle fluids that do not have enough lubricatingvalue and also very low or high viscous products Consequently since there isno metal to metal contact wear and tear is reduced to the minimum ensuringextremely long service life With two pairs of screws running in the samecasing the internal velocities are very small  consequently the NPSHR ispractically the lowest even when the pumps run at motor speeds and whilehandling viscous products Opposed screw pitches totally eliminate axialthrusts Relatively small diameters of screws enables the pump to operate athigh speeds directly coupled to prime movers  without the need for speedreducers even while handling high sealings always under suction pressure thusmaking use of simple inexpensive seals The axial flow without turbulencerotation churning chewing guarantees gentle handling of products Noise andvibration or levels are about the lowest Positive clearance between runningparts makes it easier to construct the pump in different materials safelyespecially in stainless steel without the fear of seizing Thus a variety offluids can easily be handled by selecting the right materials of construction
