Rotary Lobe Pump Technology
These pumps, also known as rotary lobe pumps, are a type of positive displacement pump well-suited for moving viscous fluids. Their efficiency increases with higher product viscosity. They are appreciated for flexibility, low pulsation, and the ability to handle both high- and low-viscosity media at variable speeds.
On this page, you’ll learn how the technology works, the operating principle, key applications, and the Packo range designed for demanding industries.
How do they work?
Operation is based on two lobes—similar to gears—rotating in opposite directions inside a casing. External timing gears keep them synchronized, maintaining a small clearance to avoid direct contact. This motion creates a vacuum that draws fluid in, traps it between the lobes and casing, and transfers it to the discharge side.
When the lobes mesh, the liquid is expelled from the pump. The following video demonstrates this process with a Packo HP/LH Hy~Line model.
Working Principle Explained
Two counter-rotating rotors draw product into the pump chamber, fill the cavities, and move it around the casing to the discharge port. Different rotor designs; single, double, tri-lobe, multi-lobe, piston circumferential, or helical—can be selected to match the material and application.
