ROTARY LOBE PUMP

Rotary lobe pumps are pumps that are part of a group of positive displacement pumps. Rotary lobe pumps are non-contacting and have large pumping chambers that allow them to handle substances that other pumps can’t handle. An example is cherries or olive that can be handled without damage, and slurries, pastes, and a wide variety of other liquids.

Because the rotary lobe pump has these attributes it is used in many industries, including pulp and paper, chemical food and beverage. Unibloc at Flowtech in Atlanta knows that nothing works without a pump that is built to fit the purpose. Our experts can advise you on the best pump to get optimum results. Rotary lobe pumps range from industrial designs to sanitary designs and the pump you require depends on the specific sanitary requirements.

Things you should look for in a rotary lobe pump depend on the sanitary qualities required, and the level of efficiency required. Reliability is essential and you need to check on corrosion resistance and good clean-in-place and sterilize-in-place characteristics.

You should also look for a company that has expert engineers at the end of a phone. There is nothing more frustrating than having a problem with your rotary lobe pump and calling the company only to find you have been put through to a call center. At Flowtech if you need a question answered, when you call our number you will speak directly with one of our expert engineers. And not only that, but to save you time we have built our website to give you much of the information you may need, without even having to make a call.

There are a number of options of Rotary lobe pumps, including single, bi-wing, tri-lobe and multilobe. Some rotary lobe pumps can offer reversible flows and can operate dry for long periods of time . Since lobe pumps can handle solids without damaging them, they are ideal for use in food applications and the size of the particles pumped can be larger than in other positive displacement pumps. However since the lobes do not make contact, and the clearances are not as close as in other positive displacement pumps, the rotary lobe pump‘s performance with low viscosity liquids is diminished. Also you must remember that this also means that suction performance is low and high viscosity liquids require speed to be reduced to achieve satisfactory performance.

So to summarize, the advantages of rotary lobe pumps are that they can pass medium solids, with no metal to metal contact; Rotary lobe pumps have superior CIP/SIP capabilities and do a long dry run, provided there is lubrication to seals. They also have a non pulsating discharge. The disadvantages of rotary lobe pumps are that they require timing gears, two seals and have reduced lift with thin liquids.
