Lobe pump

At Alflow, we sell lobe pumps – also called lobe rotor pumps – for the pharmaceutical, process, chemical and food industries. The pumps are produced in durable materials that help ensure an efficient experience. See the selection of diaphragm pumps from leading manufacturers on this site, and transport the particular fluids in the best way.

What is a lobe pump?

Lobe pumps, which are positive displacement pumps, are an effective solution for complicated tasks involving the transport of viscous products, and they are also suitable for handling abrasive products.

Lobe pumps have a modular design that makes it quick and easy to change main parts such as the rotor. This results in good service, a long service life and easy and cheap maintenance.

Our lobe rotor pumps, which are volumetric lobe pumps manufactured in AISI 316 stainless steel and special alloys (Hastelloy, Monel, Titanium), meet most transfer applications to suit hygienic and chemical properties.

Find the right lobe pump for your process

A lobe pump can of course be used for several different purposes. We have mentioned below, some of the places where you can use a lobe pump:

  • Food production
  • Beverage production
  • Chemical production
  • Pharmaceutical manufacture
  • Cosmetic manufacture
  • Pulp and paper manufacturing
  • Biotechnology

Our lobe pumps have double conical bearings and a super strong gearbox, which together with the thick shafts, gives them extra strength and a longer lifespan. They also have the smallest axle overhang on the market, the greatest possible pumping power

The dual-wing rotor in anti-seizure results in smaller tolerances and higher efficiency, while the non-contact lobes provide maximum effect and product safety.

The lobe pump is also available in a monobloc design, which provides a smaller footprint.

The B-series pumps represent reliability in terms of performance, constructive solidity, easy maintenance and low operating costs.

The pumps in the C and CF series are designed to achieve the highest hygienic-sanitary standard. They are easy to clean in order to reduce consumption of hot water and the use of chemical products for washing.

The BF/F series has been redesigned from the B Series in order to maintain performance, solidity and reliability. Made with AISI 304 gearbox and a new design, which is easier to clean.

The pump in the BE series has a simple and robust construction and is distinctive for its monobloc design. Since the rear cover is equipped with an IEC flange, the motor is attached directly to the pump, making it more compact.

BB/AA is redesigned from the B Series to maintain performance, solidity and reliability. The BB/BA series stands out with a design in accordance with 3A Sanitary Standard.

Fluids for lobe pumps

The lobe pump is versatile and designed to handle viscous products. For example, it is compatible with:

  • Chocolate
  • Aggressive chemicals
  • Powder
  • Abrasive media
  • Shampoo
  • etc.

How to operate a lobe pump

Our lobe pumps in AISI 316 stainless steel are assembled on a cast-iron transmission gearbox that has a protective epoxy-paint coating. The chamber that separates the rotor case and the gearbox makes it possible to fit mechanical seals, with which the risk of contamination between the pumped liquid and the gearbox lubricant is avoided.

Designed for easy installation in both horizontal and vertical pipelines, the lobe pumps are modular so that the main parts such as the rotor and seals can be changed quickly and easily.

Quality and high precision work is achieved by having compact and rigid mechanical parts including double-tapered roller bearings, shafts and oversized gears running in an oil bath in the gearbox.

This results in smaller tolerances, as the rotors have no contact points. This ensures a good pump performance and high reliability.

In rotor lobe pumps, the rotors rotate in opposite directions without contact with each other. In this way, the metal parts do not wear out and contaminate the product, and there is no damage to the product either.

The transmission movement from the motor drive shaft to the driven shaft is carried out by high-precision double gears. The timing device is simple and accessible – one gear is fixed and the other gear is adjustable.
