How does a rotary lobe pump work?

Bonve rotary lobe pump, or lobe pump, is a type of positive displacement pump. It consists 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.

What is the structure of a bare shaft lobe pump?

BONVE bare shaft pump is mainly composed of rotor, chamber, shaft, mechanical seal, bearing, gear and gear box. All these core components are processed by CNC, which are high-precision fabrication.


What is the main feature of a lobe pump?

  • Gap is kept between the rotor and the rotor, the rotor and the pump body. No friction, long service life.

  • All main parts are processed by CNC, which have high precision.

  • Pump connection types can be flange, screw, clamp type, etc.

  • Pump can be equipped with fixed speed geared motor or adjustable speed geared motor. The pump flow and pressure can be adjusted at will with VFD controlled.

  • The transportable medium viscosity is upto1.5 million cp, and the slurry with a solid content upto 70%.

  • Pump can transport three-phase mixture materials such as vapor, liquid and solid.

  • Simple assembly and disassembly, easy maintenance and cleaning, and few wearing parts.

  • Energy saving, low failure rate, reliable sealing and low noise.

Bonve rotary lobe pumps are designed based on the exploration of more than 3,000 fluids in various industries. They are particularly, effectively pumping for high viscosity, high solids and corrosive fluids. For more than a decade, Bonve rotary lobe pumps have been developed to the 4th generation, which further extends the service life of the pump. From 2001 to 2020, we have worked with 4000+ customers and had 50000+ pumps running in the world. We are looking forward to work with your pump demands.

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
