Products Details

Positive displacement rotary lobe pump features different driving type for your demands. The unique working principle of rotary lobe pump, combined with a powerful drive system, ensures that the pump can output a powerful drive torque at low speeds, ensuring continuous, no-retention transfer and ensuring that the transferred material is not damaged.


DRIVING TYPE


Step-less speed regulator +motor: The speed regulator changes the speed by manual adjustment, which is safe, reliable and infinitive flow adjustment. But the non-automatic adjustment is also troublesome. Speed regulating should be done in operation not in shut-off state.

Gear reducer + motor: the driving is easy with constant rotary speed of the rotor, which also leads to non adjustability of flow.

Frequency transformed motor + transducer: it realizes both automatic adjusting and infinitive adjustment of flow. It is highly automatic and has large torque in low speed.


WORKING PRINCIPLE FOR ROTARY LOBE PUMPS


Positive displacement rotary 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 STRUCTURE ADVANTAGES

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.
