Bonve rotary lobe pumps are designed based on the exploration of more than 3,000 fluids in various industries. They are particularly, effectively pumping for high viscosity, high solids and corrosive fluids. For more than a decade, Bonve rotary lobe pumps have been developed to the 4th generation. The extensive application of Bonve 4th generation pumps in various fields benefits from innovative structural design and large experience accumulation.
In response to the traditional pump problems in the paper industry, Bonve Pumps analyzed and studied various materials and process conditions in papermaking. Bonve successfully developed three series of special pumps for papermaking: Special pump for papermaking coating, special pump for papermaking surface sizing agent and special pump for papermaking chemicals, and it has been widely used in large paper mills such as Chenming Group, Xianhe Corp., Sun Holdings Group, Lee & Man Paper, Dongguan Jianhui Paper, Nine Dragons Paper Group, and Shanying Paper.
Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.
■Gap is kept between the rotor and the rotor, the rotor and the pump body. No friction, long service life.
■AII main parts are processed by CNC, which have high precision.
■Simple assembly and disassembly, easy maintenance and cleaning, and few wearing parts.
■Energy saving, low failure rate, reliable sealing and low noise.
■Pump flow can be adjusted at will with VFD controlled, and it can be used as a metering pump.
■Pump connection types can be flange, screw, clamp type, etc.
■The transportable medium viscosity is upto1 .5 million cp, and the slurry with a solid content upto 70%.
■It can transport three-phase mixture materials such as vapor, liquid and solid.
Rotor: The error of the rotors processed by CNC is extremely small. The unique rotor type perfectly seals the inlet and outlet of the pump. The vacuum degree of the pump is up to -0.095MPA. The rotor material and type can be selected according to the characteristics of the pumped product.
Shaft: The transmission shaft is processed by CNC machining center, which has the characteristics of high precision, high bending strength and strong wear resistance.
Pump cavity: The pump cavity is sealed by a pump cover that can be opened quickly, enabling quick maintenance of the pump. The pump body is processed by CNC machining center, and the pump body is processed in strict accordance with the US 3A standard to meet the requirements of CIP and SIP.
Gears: High-precision, high-standard synchronous gears have good meshing, smooth transmission, low noise, and excellent bearing capacity.
Mechanical seal: The seal material and type are selected according to the characteristics of the pumped product, to ensure zero leakage, no pollution, and more environmental protection.
Bearings: Six bearings arranged in a separate arrangement increase the concentricity of the pump operation, enhance the bearing capacity of the shaft and make the structure more stable, thereby increasing the service life of the shaft and the mechanical seal.
Gear box: The gear box is processed by CNC, with high precision, high concentricity and strong versatility.
