We are industry major name in manufacturing and supplying a qualitative assortment of Twin Screw Pump. Built in with external timing gears and bearings, these pumps are used for handling non-homogeneous fluid and abrasives like lime, acid, caustic soda and bitumen. Our Twin Screw Pump is designed and manufactured by our professionals as per the set industry norms using supreme grade materials. Be it in domestic market or international, our offered pumps are cherished and acknowledged over the global platform.
FEATURES:Positiveclearance between rotors ensures no metal to metal contact. This unique featureenables to run the pump even dry for some time without any damage & wearand tear is reduced to the minimum ensuring extremely long service life.

WORING PRINCIPLE: A pair of speciallyprofiled screw, machined integral from solid stock and well supported onantifriction bearings run in precision bored interchangeable casing liners.Each 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 turbulence,rotation, 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 safely,especially in stainless steel, without the fear of seizing. Thus a variety offluids can easily be handled by selecting the right materials of construction.
