Tushaco Pumps
Tushaco has been manufacturing positive displacement pumps since 1968 and is considered to be one of the leading names in India and abroad. Tushaco is also credited with the introduction of several new designs of pumps for the first time in the country. Some of them being: Shuttle Block Pumps, Rotary Trocoidal Internal Gearing Principle RT series, Three Screw and twin Screw Pumps.Tushaco Three Spindle Screw Pump ( Series T3S )
Working Principle
TUSHACO Three Screw pumps employ just three screw elements - one power screw and two idler screws running in the three precision bores in the housing or liner. The screws are so profiled that they form a liquid tight seal between the thread. As the screws rotate, pockets/ cavities are formed where liquid gets trapped and conveyed from one end of the infinite stroke. This results in smooth, pulsation free flow with extremely low noise and vibration levels, almost impossible to be achieved by any other design of positive displacement or other types.

Tushaco Internal Gear Pumps
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 a small, but positive clearance to achieve perfect scaling between parts. As the gears come out of mesh, a partial vacuum is created, forcing the fluid to rush into the pump casing and fill in the voids between the teeth. Both gears rotating in the same direction of rotation gently transfer 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 and even pump casing simply by removing the front cover without disturbing drive parts, bearings etc., and in place. Block pump mounted integrally on hollow shaft gearbox automatically reduces 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. | ||||||||||||

Tushaco Progressing Cavity Pump
Design and Operation
Tushaco progressing cavity pump is a positive displacement rotary pump. The actual pumping elements of the pump are rotor and stator. The single helical rotor rolls eccentrically in a double threaded helix stator of twice the pitch length. A series of sealed cavities 180° apart are created that appear to progress from suction to discharge during one rotation of rotor.
