Internal Gear Pumps
Internal Gear Pump with Crescent is mainly developed for catering the need of fuel firing as well as for the liquids with poor lubricating properties under wide temperature range.
As the double-start screws meshes, a continuous axially moving voids/pockets generate, which traps the liquid inside it, and hence transfers the fluid, where it required.
These pumps permits an even axial flow without pulsation and silent pumping operation even at a high speed. Axial loads on the rotor are often compensated by an adequate design of the bearing and all the radial forces are self-compensated.
Further, size of a rotor kept small in the design, which enables these pumps to run at a higher speed with direct coupling to the prime mover. Self-compensated radial forces eliminate need of bearing High pressure capacity up to 40 Bar Self-Priming and reversible cartridge design simplifies maintenance problem and saves lead time.
