WORKING PRINCIPLES



Bonve high pressure electric lobe pump


The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.

PUMP DRIVING


BONVE Lobe pumps can be supplied bare shaft (without drive) or mounted on a base plate with drive. For the drive, geared reducer with motor is commonly used since lobe pumps are generally operate at low to medium speeds i.e. 40 to 600 rev/min. The geared motor is direct coupled to the pump drive shaft via a flexible coupling. Pls refer to the structure. For pump working speed, it can be fixed or regulated as per your request
 
Fixed Speed
When exact flow is not critical a fixed speed drive is generally used.  

Variable Speed
To handle changing duty conditions or a number of different duties, it may be necessary to use a variable speed drive or frequency converter to obtain correct pump duty speeds. The frequency converter allows the operator to change the frequency of the electric motor, thereby changing pump speed and controlling flow.
