Rotary Lobe Pumps

Superb sanitary qualities, high efficiency, reliability, corrosion resistance and good clean-in-place / sterilise-in-place (CIP/SIP) characteristics. Rotary lobe pumps are non-contacting and have large pumping chambers which allows for handling of solids such as cherries or olives without damage.

Rotary Pumps or Rotary Lobe Pumps use the principles of rotation to create a vacuum which draws fluid into the pump. The rotating lobes create expanding volumes on the inlet of the pump where the fluid flows into the cavity and is trapped and carried around by the lobes to the outlet of the pump. The pumped fluid travels between the pump casing and the lobes (rotors). The rotors re-mesh and force the fluid through the pump outlet under pressure. Pump output is constant and continuous.

When to use Rotary Pumps

Rotary Lobe Pumps are high hygiene pumps and offer excellent sanitary qualities. They are also highly efficient, reliable, corrosion resistant and can easily be cleaned in place (CIP).

Rotary pumps can handle solids, slurries, pastes and many liquids. If wetted, they offer self-priming performance. The pumps offer continuous and intermittent reversible flows and can run dry for limited time periods.

Rotary Lobe pumps are very good at handling solids without inflicting damage to the product. Particle sizes can be much larger than most other positive displacement pumps and the pumps are used in many industries including:
