Chemical grade lobe pump for resins

Resin is very special product which has not high viscosity but very sticky. Normal pumps could not work well with it because of unsuitable seal structure. We Bonve overcome this problem and develop the seal type especially for resin. Resin has many applications, ranging from art to polymer production, and many consumers interact with products that contain it on a daily basis. Bonve pumps are highly acknowledged in these applications because of no wearing parts, low maintenance and long life. More and more customers are using Bonve pumps to replace their original gear pumps.

Products Details

Bonve industrial rotary lobe pumps are widely used in the fields of daily chemicals and fine chemicals. As a pioneer with 17 years of experience, we always keep updating our pumps and applied for a variety of patents, make sure higher compatibility for pump sealing, more stability when working under high pressure and so on. As an excellent manufacturer, our hard technical barriers have become a powerful help for our Bonve pump reform and innovation. So far, our pumps have developed to the fourth generation, which is long lasting, leak free, and proven in many harsh applications.

In the transportation of resin, we have a wealth of experience, considering that the resin is semi-solid at room temperature during transportation, so we will use a pump with a thermal insulation jacket, and we have six bearings in our pump, so that our pump has higher stability. The picture below is the application of our pumps in the resin industry.

How pump works?


Bonve industrial rotary 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.

Note:
1. Tested medium: water. Your liquid's density, viscosity and temperature are necessary to supply when choose the pump.
2. Speed, flow rate, electrical power and pressure will be varified according to different liquid properties.
3. Port size can be changed as needed.


What its advantages?


  • Displacement: positive displacement, Displacement is proportional to the speed. 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.
