The very first pump produced by TUSHACO in 1968 was an Internal Gear Pump Model R-1-G for low-pressure burner service - till this day it is in production with great success. Subsequently only TUSHACO had the foresight to introduce several other exotic designs, to take care of growing industrial demands, thus placing themselves on the forefront in the field of Rotary Positive Displacement Pumps. Experience gained over years in designing and building Rotary Pumps combined with knowledge in Application Engineering has resulted inthis development of New Stainless Steel Internal Gear Series specifically for food, chemical and pharmaceuticalindustry. Computer aided designs, CNC in-house machining facilities and sophisticated test beds, together with TUSHACO dedication made instant success of the New Internal Gear "IG" series from day one.

Innovation, simple construction has ensured very easy maintenance and totally reliable hassle free installation. A glance at the reference list of scores of pumps delivered for New Food Processing and Industrial projects within a short period is a silent testimony for TUSHACO performance.

Working Principle

TUSHACO IG series employs proven Internal Gearing (Gear within Gear) principle for pumping. The main gear is keyed to the drive shaft, and rotates concentric in the pump casing. Idler is located on an eccentric pin on the front cover to rotate freely and meshes with main gear when assembled. A crescent shaped partition precision machined on the front cover maintains asmall, but positive clearance to achieve perfect scaling between parts. As the gears come outof mesh, a partial vacuum is created, forcing the fluid to rush into the pump casing and fill inthe voids between the teeth. Both gears rotating in the same direction of rotation gentlytransfer the fluid to the delivery port. The resulting action is a smooth-steady flow; low in pulsation, noise and vibration.

Single shaft design well supported on outboard bearing (except for one inside sleeve bearing) enables to pump products even with poor lubricating value unlike in the external gear pumps. External bearing construction offers easy access the pump components i.e., rotor set andeven pump casing simply by removing the front cover without disturbing drive parts, bearingsetc., and in place. Block pump mounted integrally on hollow shaft gearbox automaticallyreduces the speed (in several ratios) and enables even the pump rotor to be pulled out without disturbing the drive! It is easily possible to jacket front and rear covers for products heating -thus making the design unique and versatile - ideally suited for process pumping.

These are more compact handy, portable, lighter in weight and hence are economically more viable for humble applications. Also these are best suited to OEM's for incorporating them in their industrial units and plants.

TUSHACO Twin Screw pumps employ a unique principle that makes it the only choice for certain applications. No other design of Positive Displacement Rotary pumps offer so much versatility in the operating parameters with guaranteed total reliability and maintenance-free service.

Working Principle

A pair of specially profiled screw, machined integral from solid stock and well supported on antifriction bearings run in precision bored interchangeable casing liners.Each screw set has one RH and one LH screw engaging with a similar but opposite hand screw pair.

A pair of hardened and profile ground timing gears synchronize the screws to maintain a small but positive clearance between the flanks thus ensuring no metal to metal contact. The pumps can therefore run dry for sometime without any damage. This unique feature enables to run the pump even dry and handle fluids that do not have enough lubricating value and also very low or high viscous products. Consequently, since there is no metal to metal contact; wear and tear is reduced to the minimum, ensuring extremely long service life. With two pairs of screws running in the same casing, the internal velocities are very small - consequently the NPSHR is practically the lowest even when the pumps run at motor speeds and while handling viscous products. Opposed screw pitches totally eliminate axial thrusts. Relatively small diameters of screws enables the pump to operate at high speeds directly coupled to prime movers - without the need for speed reducers even while handling high sealings always under suction pressure, thus making use of simple, inexpensive seals. The axial flow without turbulence, rotation, churning, chewing guarantees gentle handling of products. Noise and vibration or ---- levels are about the lowest. Positive clearance between running parts makes it easier to construct the pump in different materials safely, especially in stainless steel, without the fear of seizing. Thus a variety of fluids can easily be handled by selecting the right materials of construction.

TUSHACO PUMPS have earned a reputation of being the most reliable Positive Displacement Pumps for practically any given application since 1968 due to the widest choice of designs available and excellent knowledge of application engineering. Continuous Research and Development together with modernization with CNC machines and testing facilities has enabled us to accept challenging jobs. Thousands of TUSHACO pumps in operation to the total satisfaction of the users in core industries throughout the country and abroad are a silent testimony.

Applications Chemical analyzersPollution control equipmentsGas monitoringNitrogen generating setsOzone generatorsOperating clinicalMedical and scientific laboratory equipmentsSuction of desoldering wasteFitrationDentistries & spray printing

Unlike oil sealed ones, water - ring vacuum pumps are capable of creating vacuum up to 710mm Hg only which is far less than what can be achieved by the former . But still are preferred in chemical and pharmaceutical industries. These prove economical and require less maintenance. Water is used in place of costly oil and no hassle of frequent oil changing. Requires less energy to run and enjoys longer life. Even noise otherwise create no pollution , no fumes and produce every little nosie. Higher vacuum through them can also be achieved when made to work as backing pumps in systems. Suit all applications covered by oil sealed pumps.

Highly Compact in design and so simple at the same time. Most reliable and efficient performer. An indispensible equipment for Scientific Labs, R&D centres, Pilot Plants and host of industrial units where it is used for vacuum loading and lifting. Available in single as well as in double stage.

ApplicationsVacuum Creation, Filling, drying, Lifting, Forming, Filteration, Distillation, Annealing, Impregnation, Dehydration, Sublimation, Film Coating & many more.
