What is a rotary lobe pump?

Rotary Lobe Pumps are positive displacement pumps able to transferring liquids products,especially for high viscosity, high solidand arefeatured aslow shearing. Gentletransferringmakes them popularused in food, cosmetics and industrial chemicalproducers. No damage to the pumped products.


How rotary lobe pumps work?



Rotary lobe pump working principle is easy to understand. They basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed.


Parts of rotary lobe pumps

The main parts are including rotors, pump cavity, mechanical seal, shaft, bearings and gears. They are processed by CNC to ensure high precision fabrication.


Constructionmaterials of rotary lobe pumps, but are not limited to:

Product contact metal parts: stainless steel AISI 316, 316L, duplex, 904L

Mechanical Shaft Seals: Tungsten carbide, Silicon carbide

Sealing Materials of O-rings: Viton, EPDM, FFKM

Lobes types and why different need

According to the different product transfer, manufacturers have different lobes design to make sure an efficient feeding and no failure, such as single-wing, bi-wing, tri-lobe, four-impeller, eight or twelve-impeller lobes. See below diagram which shows each lobes type application.

How to troubleshoot when the homogenizer mixing pump fails - bonvepumps.com

图片
  High shear homogenizing mixer   will inevitably encounter some failures during use. At this time, it is necessary to find out the cause of the   high shear homogenizing mixer   failure through troubleshooting, and then find out the countermeasures based on the cause of the failure. The following are some of the faults that may occur in the  high shear homogenizing mixer . You can check according to the use of the  high shear homogenizing mixer . When the pump does not discharge or less capacity 1. Check whether the valve at inlet and outlet pipe open. 2. Whether the pipeline setting of the  high shear homogenizing mixer  is too complicated. 3. Whether the inlet and outlet pipelines of the pump are blocked. 4. The concentration and viscosity of the processed product will reduce the production efficiency of the  high shear homogenizing mixer  or not discharge the product. Solution: Add a feeding pump to the feed port of the mixer or dilute the product before entering the feed port of t
