Internal gear Varisco pump: How it works

The Varisco V and SAXMAG V series internal gear pumps are designed to work in demanding environments and are used to transport viscous liquids even if they contain abrasive powders, as long as they do not contain solid bodies.

V and SAXMAG V pumps: Working principle

V and SAXMAG V pumps are internal gear positive displacement rotary pumps. The flow is generated by two gears: the rotor and idler, one inside the other, separated by a crescent. As the gears rotate, liquid is drawn into the spaces created between the gears and the crescent. When the gears mesh, the liquid is forced out of the pump. The result is a smooth flow of liquid and high capacity combined with compact size.
