Lobe Pump

About Lobe Pump

Lobe Pump

We are one-step ahead of our competitors in manufacturing and wholesaling a wide range of Jaketed Stainless Steel Lobe Pumps. These find their wide application in various industries including food processing, beverages, dairy, pharmaceutical and many other allied industries. ergonomic design of these pumps reflect the hard labor and long research work of our experienced engineers. Besides, these pumps also ensure easy installation, corrosion resistance and long functional efficiency.

Specifications:

• As the rotors start to rotate, an expanding cavity is formed by rotation of the lobes which creates a vacuum at the inlet port, drawing liquid in pumping chamber.

• The product liquid is carried between the lobes and positively displaced, thereby sealing itself against the internal faces of the pump casing.

• The other lobe chamber is filed with the product liquid and about to commence it's discharge cycle.

• Finally the product liquid is forced or pressed out of discharge port of the pump in continuous smooth flow  and pressure generated by the meshing of the lobe rotors

MICROTECH ENGINERING  Lobe pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, Pharmaceutical, and biotechnology. They are popular in these Diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics.These pumps offer a variety of lobe options including single, biwing, tri-lobe (shown), and multi-lobe.Rotary lobe pumps are Non-contacting and have large pumping chambers, allowing them to handle solids such as cherries or olives without damage. They are also used to handle slurries, pastes, and a wide variety of other liquids. If wetted, they offer self- priming performance. A gentle pumping action minimizes product degradation. They also offer reversible flows and can operate dry for long periods of time. Flow is relatively independent of changes in process pressure, so output is constant and continuous.

How Lobe Pumps Work Liquid flows into the cavity and is trapped by the lobes as they rotate.

Lobe pumps are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the lobes do not make contact. Lobe contact is prevented by external timinggears located in the gearbox. Pump shaft support bearings are located in the gearbox, and since the bearings are out

of the pumped liquid, pressure is limited by bearing location and shaft deflection.

Advantages

  Pass medium solids

· No metal-to-metal contact

· Superior CIP/SIP capabilities

· Long term dry run (with lubrication to seals)

· Non-pulsating discharge

Disadvantages

· Requires timing gears

· Requires two seals

· Reduced lift with thin

Versatile Rotor Designs for Optimum Performance

Choose between bi-lobe, tri-lobe, or multi-lobe rotors to match the flow and viscosity requirements of your process. These rotor types ensure efficient, low-shear transfer of sensitive products and enhance pump adaptability across industrial and sanitary applications.


Superior Viscosity Handling and Hygienic Construction

Designed to handle fluids up to 1,000,000 cP, this pump meets strict hygienic standards with a smooth surface finish (RA 0.3 to 0.6 m) and robust SS304/SS316 or cast iron body. All wetted parts are engineered for gentle product handling, minimizing damage and contamination risk.


Explosion-Proof & Certified for Safe Operation

Optional flameproof motors and third-party certification ensure safe operation in hazardous environments, supporting compliance with ISO and GMP standards. The pumps are validated by recognized authorities, guaranteeing reliability and suitability for demanding industrial conditions.


Maintenance Made Easy: Quick Strip & Serviceability

With a base plate-mounted structure and quick-strip design, routine maintenance and cleaning can be carried out swiftly. The pumps Clean-In-Place (CIP) and Steam-In-Place (SIP) capabilities further streamline hygiene processes for uninterrupted production cycles.
