INTERNAL GEAR PUMPS – IG Series

The Internal gear pump employs proven Internal gearing (Gear within gear) principle for pumping. As the gears come out of mesh, a partial vacuum is created, forcing the fluid to rush into the pump casing and fill in voids between teeth. Both gears rotating in the same direction of rotation gently transfer the fluid to the delivery port.

CONSTRUCTION:

Single shaft design well supported on outboard bearing enables to pump products even with poor lubricating value. 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.
