Product Description

Internal Gear pump

Product Features

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 sealing 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 product heating - thus making the design unique and versatile - ideally suited for process pumping.
