Products Details

Bonve Stainless steel industrial lobe pumps are popular in chemical industries because they offer high efficiency, reliability, corrosion resistance and easy maintenance characteristics. Lobe pumps can handle slurries, pastes, and a variety of liquids. If wetted, they offer self-priming performance. A gentle pumping action minimizes product degradation. They also offer continuous and intermittent reversible flows and can operate dry for brief periods of time. Flow is relatively independent of changes in process pressure, too, so output is relatively constant and continuous.

WORKING PRINCIPLES



Bonve Stainless steel industrial lobe pumps


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 TECHNICAL FEATURES

  • Displacement: positive displacement, Displacement is proportional to the speed. Max. Capacity is upto 300m3/h.
  • Discharge pressure: upto 1.2Mpa.
  • Suction capacity: Movable pumps can be used to pump canned medium, with intake vacuum of 0.08 Mpa.
  • Work efficiency: upto 90%
  • Special mediums to handle: high viscosity upto 1.5million cps, high solid mediums upto 60%, sensitive mediums.
  • Reversible running allowed: Forward suction, reversal flushing can be realized with pump's symmetric structure, reversible transportation direction.
  • Dry running: with Bonve's special design on mechanical seal, dry running can be realized.
  • Maintenance: Compact structure, little space occupation, no need to move pipe systems when maintain.
  • Wear-resisting: all the contact parts are made of stainless steel. Nearly no wearing parts.
  • Low shearing: Low working speed, gap is kept between the rotors and between the rotor and the pump body, no friction,long life.
  • Replacement: take replace of screw pumps, gear pumps, centrifugal pump,diaphragm pump etc.
  • Low cost: high working efficiency, low consumption, environmental friendly, low maintenance, long life.


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
 BONVE Lobe pumps
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.
