ROTOMAC™ Rotary Lobe Pumps
ROTOMAC Rotary Lobe Pumps are positive displacement pumps specifically designed for hygienic processing. Two synchronised lobes rotate without touching each other or the pump casing, creating sealed fluid chambers that transport product gently from inlet to outlet — with no damage to shear-sensitive or particulate-containing products.
The sanitary construction makes these pumps the preferred choice for food production, dairy, beverage, cosmetics, and pharmaceutical manufacturing — wherever product integrity, hygiene, and cleanability are critical requirements.
Operating Principle
Two synchronised rotors (lobes) rotate against each other, building chambers towards the casing of the pump. At the suction side, the fluid enters the chambers and during rotation, the fluid is displaced in the direction of the volume flow into the discharge side — providing smooth, positive displacement transfer without pulsation.
The Rotary Lobe Working Principle
Three precise operating stages deliver smooth, hygienic positive-displacement flow every rotation cycle.
Lobe Unmesh — Suction
As the two synchronised rotors (lobes) rotate and unmesh at the suction port, they create expanding chambers. The resulting low pressure draws fluid into the pump from the suction side.
Sealed Chambers — Transport
The fluid is sealed within the chambers formed between the lobes and the pump casing. As the lobes rotate, the sealed fluid pockets are transported around the inside of the casing towards the discharge side — no product degradation, no shear.
Lobe Mesh — Discharge
At the discharge port, the lobes remesh, reducing the chamber volume and gently displacing the fluid out through the discharge connection — producing a smooth, non-pulsating, volumetrically consistent output.
