Bonve Rotary
Lobe Pumps for glycerin
Glycerol is also
called glycerine or glycerin. It is a colorless, odorless, viscous liquid
that is sweet-tasting and non-toxic. The glycerol backbone is found in
many lipids which
are known as glycerides. It is widely used in the food industry as a
sweetener and humectant in pharmaceutical. Glycerol has
three hudroxyl groups that are responsible for
its solubility in water and its hygroscopic nature.
How to choose pump?
Glycerol transfer pumps for food, cosmetics, and pharmaceutical,
must meet the hygiene requirements. Bonve offers its Sanitary Rotary Lobe Pumps for this
application. They are popular used because they offer superb sanitary
qualities, high efficiency, reliability, corrosion resistance and good
clean-in-place and steam-in-place (CIP/SIP) characteristics. 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.
How Bonve pump works?
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 main structure
Bonve Rotary lobe pumps are mainly composed of bare shaft pump, coupling, coupling guard, geared reducer with motor and base. The core parts are rotors, chamber, shaft, mechanical seal, gears, bearings and gear box, which are processed by CNC machine, which guarantees high precision and concentricity, results in a low maintenance and long life pump.
